Remove relics of regex swash use
This removes the most obvious and easy things that are no longer needed
since regexes no longer use swashes at all.
tr/// continues, for the time being, to use swashes, so not all swash
handling is removable now. But tr/// doesn't use inversion lists, and
so a bunch of code is ripped out here. Other code could have been, but
I did only the relatively easy stuff. The rest can be ripped out all at
once when tr/// is stops using swashes.

regcomp.c: Arrays no longer need PL_sv_undef placeholders

regcomp.c: Simplify args passing for ANYOF nodes
A swash is no longer used, so we can remove some elements from the array
of data that gets stored with the compiled pattern for use in runtime
matching. This is the first step in more simplifications.
Since a swash isn't used, this change also requires regexec.c to change
to use a straight inversion list lookup. This has the salutary effect
of eliminating a conversion between code point and UTF-8.

t/re/regexp_unicode_prop.t: Make sure sub called only once
User-defined properties are supposed to be called just once for /i and
once for non-/i. This adds tests for that.
It turns out that this was broken in blead.

regcomp.c: Add some potential code that's #ifdef'd out
This is in case we ever need it. This checks for portability in the
code points specified in user-defined properties. Previously there was
a check, but I couldn't get a warning to trigger unless there was also
overflow. So that means the pattern compile failed due to the overflow,
and the portability warning was superfluous. But, one can have
non-portable code points without overflow; just the old method didn't
properly detect them. If we do ever need to detect and report on them,
the code is mostly written and in this commit.

XXX perldelta; more msg Move \p{user-defined} to core from utf8_heavy.pl
This large commit moves the handling of user-defined properties to C
code. This should speed it up, but the main reason to do this is to
stop using swashes in this case, leaving only tr/// using them. Once
that too is converted, all swash handling can be ripped out of perl.
Doing this in perl has caused some nasty interactions that will now be
fixed automatically.
The change is not entirely transparent, however (besides speed and the
possibility of removing these interactions). The known changes are:
1) A few error messages have minor wording changes. This is
essentially because the new way is integrated into the regex error
handling mechanism that marks the position in the input that the
error occurred at. That was not possible previously.
2) A user-defined property is implemented as a perl subroutine with
certain highly constrained naming conventions. It was documented
previously that the sub would be in the current package if the
package was unspecified. This turned out not to be true in all
cases, and this commit fixes it so that it is always true.
3) All recursive calls are treated as infinite recursion. Previously
they would cause the interpreter to panic. Now, they cause the
regex pattern to fail to compile.
4) Similarly, any other error likely would lead to a panic; now to just
the pattern failing to compile.
5) The old mechanism did not detect illegal ranges in the definition of
the property. Now, the range max must not be smaller than the range
min. Otherwise, the pattern fails to compile.
6) The intention was to have each sub called only once during the
lifetime of the program, so that a property's definition is
immutable. This was relaxed so that it could be called once for all
/i compilations, and potentially a second time for non-/i (the sub
is passed a parameter indicating which). However, in practice there
were instances when this was broken, and multiple calls were
possible. Those have been fixed. Now (besides the /i,non-/i cases)
the only way a sub can be called multiple times is if some component
of it has not been defined yet. For example, suppose we have sub
IsA() whose definition is known at compile time, and it in turn
calls isB() whose definition is not yet known. isA() will be called
each time a pattern it appears in is compiled. If isA() also calls
isC() and that definition is known, isC() will be called just once.

Add global hash to handle \p{user-defined}
A global hash has to be specially handled. The keys can't be shared,
and all the SVs stored into it must be in its thread. This commit adds
the hash, and initialization, and macros for context change, but doesn't
use them. The code to deal with this is entirely confined to regcomp.c.
