hints/hpux.sh: HP-UX mbrlen() and mbrtowc() don't work
In spite of there being man pages for these, the #include file doesn't
define the mbstate_t type which is required for a parameter to these
functions.
Perhaps the Configure probe could be enhanced so it doesn't return
defined unless these can be successfully compiled, but for now use the
hints file.

Avoid changing locale when finding radix char
On systems that have the POSIX 2008 operations, including
nl_langinfo_l(), this commit causes them to not have to actually change
the locale when determining what the decimal point character is.
The locale may have to change during the printing/reading of numbers,
but eventually we can use sprintf_l(), if available, to avoid that to.

Perl_sv_2pv_flags: Potentially avoid work
By using a macro that is private to the core, this code can avoid
thinking it has to deal with a non-dot radix character, as even if we
are using the locale radix, that is often a dot.

Latch LC_NUMERIC during critical sections
It is possible for operations on threaded perls which don't 'use locale'
to still change the locale. This happens when calling
POSIX::localeconv() and I18N::Langinfo(), and in earlier perls, it can
happen for other operations when perl has been initialized with the
environment causing the various locale categories to not have a uniform
locale.
This commit causes the areas where the locale for this category should
predictably be in one or the other state to be a critical section where
another thread can't interrupt and change it. This is a separate
mutex, so that only these particular operations will be held up.

locale.c: Do savepv() ASAP
When this code is called on a threaded perl, it's possible that another
thread could zap the setlocale return buffer, if it's not reentrant. I
suspect we would have seen this more often if that was the case, but
this commit improves things by doing the save immediately, reducing the
unsafe interval.

Add mutex for changing LC_NUMERIC
But don't use it yet.
Changing of LC_NUMERIC is done by the perl core, and is a potential race
condition on threaded perls. This adds a mutex that later commits will
use to create critical sections where the value of LC_NUMERIC matters.

POSIX::strftime: Add better fallback about UTF-8
If the function returns a valid string that isn't completely UTF-8
invariant, the function assumes it is UTF-8 if we are in a UTF-8 locale.
This works, but in the unlikely event that the system has no LC_TIME, we
can't tesll if it is in a UTF-8 locale. As a better fallback position,
this commit adds the check that there is just a single script of the
time string, adding a measure of reassurance that out call that it is
UTF-8 is correct.
This is unlikely to be used, but now that there is a function to call
that determines if this is a script run, it's easy to add, and unlikely
to actually get compiled.

other uses where the dot is not correct, so remove it.

locale.c: Revamp fallback detection of UTF-8 locales
This commit continues the process started in the previous few commits to
improve the detection of whether a locale is UTF-8 or not when the
platform doesn't have the more modern tools available.
What was done before was examine various texts, like the days of the
week, in a locale, and see if they are legal UTF-8 or not. If there
were any, and all were legal, it assumed that UTF-8 was needed. If
there weren't any (as in American English), it looked at the locale's
name. This presents false negatives and false positives.
Basically, it adds the constraint that all the texts need to be in the
same script when interpreted as UTF-8, which basically rules out any
false positives when the script isn't Latin. With Latin, it isn't so
clear cut, as the text can be intermixed with ASCII Latin letters and
UTF-8 variant sequences that could be some Latin locale, or UTF-8, and
they just coincidentally happen to be syntactically UTF-8. Because of
the structuredness of UTF-8, the odds of a coincidence go down with
increasing numbers of variants in a row. This also isn't likely to
happen with ISO 8859-1, as the bytes that could be legal continuations
in UTF-8 are almost entirely controls or punctuation. But in other
locales in the 8859 series, there are some legal continuations that
could be part of a month name, say.
As an example of the issues, in 8859-2, one could have \xC6 (C with
acute) followed by \xB1 (a with ogonek), which in UTF-8 would be
U+01B1: LATIN CAPITAL LETTER UPSILON. However, something like \xCD
(i acute) followed by \xB3 (l with stroke) yields U+0373: GREEK
SMALL LETTER ARCHAIC SAMPI, and the script check added by this commit
would catch that. In non-Latin texts, the only permissible ASCII
characters would be punctuation, and you aren't going to have many of
those in the LC_TIME strings, and certainly not in a row. Instead those
will consist of at least several variant characters in a row, and the
odds of those coincidentally being syntactically valid UTF-8 and
semantically in the same script are exceedingly low.
To catch Latin UTF-8 locales, this commit adds a list of the distinct
variants found so far. If there are even just several of these, the
odds of the syntax being coincidentally UTF-8 greatly diminish. The
number needed for this to conclude that the locale is UTF-8, is easily
tweakable at compile time.
The problem remains for English and other Latin script languages that
have rare accented characters. The name is still then examined for
containing "UTF-8". Note that previous commits have guaranteed that if
the locale has a non-ASCII currency symbol that is recognized by
Unicode, such as the Euro or Pound Sterling, that will correctly be
recognized.

locale.c: Improved fallback UTF-8 locale detection

Improve fallback UTF-8 locale detection
If the libc doesn't have modern enough routines, we use a fallback
mechanism to see if a locale is UTF-8 or not. One component of this is
to look at the byte sequence for the currency symbol. Obviously, if the
sequence isn't valid UTF-8, the locale isn't either. But if it is valid
UTF-8, and hence might be a UTF-8 locale, this commit changes the
detection mechanism to see if the sequence evaluates, when interpreted
as UTF-8 to be a known Unicode currency symbol. If so, the locale must
be UTF-8, as the odds of some other locale having a sequence that does
this are vanishingly small.
If the sequence doesn't evaluate to a currency symbol, that doesn't tell
us anything, as plenty of places have a string of letters be their
currency symbol. Nor if the symbol is a '$', as that is invariant under
UTF-8 vs not, so doesn't help us.
This pretty much guarantees that a UTF-8 locale for the European Union
or the UK that otherwise looks like plain English (Latin script) will be
properly determined to be UTF-8, as the symbols for their currencies
will pass this test.

locale.c: Revamp finding if locale is UTF-8
This changes how this functionality works for the LC_CTYPE locale. On
systems that have nl_langinfo() one can get a definitive answer from
just that. Otherwise (or if that doesn't return properly) one can use
mbtowc() to check if the UTF-8 byte sequence for the Unicode REPLACEMENT
CHARACTER actually is considered to be that code point. This is also
definitive. If the maximum byte string length for a character is too
short to handle all Unicode UTF-8, we know without further checking that
this isn't a UTF-8 locale, so can avoid the mbtowc check.

Cache locale UTF8-ness lookups
Some locales are UTF-8, some are not. Knowledge of this is needed in
various circumstances. This commit saves the results of the last
several lookups so they don't have to be recalculated each time.
The full generality of POSIX locales is such that you can have error
messages be displayed in one locale, say Spanish, while other things are
in French. To accommodate this generality, the program can loop through
all the locale categories finding the UTF8ness of the locale it points
to. However, in almost all instances, people are going to be in either
French or in Spanish, and not in some combination. Suppose it is a
French UTF-8 locale for all categories. This new cache will know that
the French locale is UTF-8, and the queries for all but the first
category can return that immediately.
This simple cache avoids the overhead of hashes.
This also fixes a bug I realized exists in threaded perls, but haven't
reproduced. We do not support locales in such perls, and the user must
not change the locale or 'use locale'. But perl itself could change the
locale behind the scenes, leading to segfaults or incorrect results.
One such instance is the determination of UTF8ness. But this only could
happen if the full generality of locales is used so that the categories
are not all in the same locale. This could only happen (if the user
doesn't change locales) if the environment is such that the perl program
is started up so that the categories are in such a state. This commit
fixes this potential bug by caching the UTF8ness of each category at
startup, before any threads are instantiated, and so checking for it
later just looks it up in the cache, without perl changing the locale.

point (radix) is a dot. For some (mostly) output purposes, it needs to
be swapped into the program's current underlying locale so that a
non-dot can be printed.
This commit changes things so that if the current underlying locale uses
a decimal point, the swap doesn't happen, as it's not needed.

locale.c: Refactor Ultrix code
Examination shows that this code does nothing unless LC_ALL is defined.
So explicitly test at compile time for that.
Also, two variables don't have to be declared so globally, and by
reducing their scope, by creating a new block we don't have to have
PERL_UNUSED_ARG()s for them

Teach perl about more locale categories
glibc has various other categories than the ones perl handles, for
example LC_PAPER. This commit adds knowledge of these to perl, so that
one can set them, interrogate them, and have libraries work on them,
even though perl itself does not.
This is in preparation for future commits, where it becomes more
important than currently for perl to know about all the locale
categories on the system.
I looked through various other systems to try to find other categories,
but did not see any. If a system does have such a category, it is
pretty easy to tell perl about it, and recompile. Use the changes in
this commit as a template, and send an email to [email protected], so
that the next Perl release will have it.

Add check that "$!" is correctly interpreted as UTF-8
We sometimes need to know if an error message is UTF-8 or not.
Previously we checked that it is syntactically valid UTF-8, and that the
LC_MESSAGES locale is UTF-8. But some systems, notably Windows, do not
have LC_MESSAGES. For those, this commit adds a different, semantic,
check that the text of the message when interpreted as UTF-8 is all in
the same Unicode script. This is not foolproof, unlike the LC_MESSAGES
check, but it's better than what we have now for such systems. It
likely is foolproof for non-Latin locales, as any message will have a
bunch of characters in that locale, and no ASCII Latin ones. For a
Latin locale, these ASCII letters could be intermixed with the UTF-8
ones, causing potential ambiguity.

isSCRIPT_RUN: Can short cut if not in UTF-8
All characters representable by single bytes are either Common or Latin,
so must be a script run. If we aren't asking for what the script is we
can return immediately. If we are, the run is Latin if any character in
it is Latin, otherwise is Common.

Fix bug in script runs that start with Common
This is a follow on to 8535a06fea02528fe726855a139fcbd360d1fc6e. That
fixed one case where the first character was in the Common script,
things did not work properly. It did not catch the case where a future
character in the string was non-Common from a script that has its own
set of digits, and this commit fixes that.
This just entails a block of code to slightly earlier.

my_atof(): Lock dot radix
This commit shows some redundant checks. It examines the text and if it
finds a dot in the middle of the number, and the locale is expecting
something else, it toggles LC_NUMERIC to be the C locale so that the dot
is understood. However, during further parsing, grok_numeric_radix()
gets called and sees that the locale shouldn't be C, and toggles it
back. That ordinarily would cause the dot to not be recognized, but
this function always recognizes a dot no matter what the locale. So
none of our tests fails. I'm not sure if this is always the case, and I
don't understand this area of the code all that well, but there is a
simple way to cause grok_numeric_radix to not change the locale back,
and that is to call the macro LOCK_LC_NUMERIC_STANDARD() when changing
it the first time in my_atof(). The purpose of this macro is precisely
this situation, so that recursed calls don't try to override the
decisions of the outer calls
