Log Message:
-----------
regen/regcomp.pl - create typedefs for all regnode types
Currently we hard code the struct used by the different regop types.
This makes it awkward to change the structure used by a specific regop
as the struct it uses might be used in many contexts, and each cases
of a regop using that structure must be reviewed to see if it needs
to be changed.
This patch adds a typedef for each regnode. The typedefs are named
'tregnode_OP', for instance 'tregnode_TRIE' is typedefed to 'struct
charclass' (at the time of this commit). This allows the code to do
things like 'sizeof(tregnode_TRIE)' and should the exact struct used
for TRIE regops change in the future then no code need be reviewed
or changed.

regen/regcomp.pl - rename regarglen to PL_regarglen for regexec.c
In a follow up patch we will use this data from regexec.c which
currently cannot see the variable.
This changes a comment in regen/mk_invlists.pl which necessitated
rebuilding several files related to unicode. Only the hashes associated
with mk_invlists.pl were changed.

Log Message:
-----------
regcomp.c - fixup comment, orig_emit is a node offset
This comment was a bit misleading, as orig_emit is an offset
into the program, not a pointer, it needs the REGNODE_p() macro
to convert from offset to pointer.

regcomp.c - add reg_nextoper and check_reg_nextoper
reg_nextoper implements dynamically finding the NEXTOPER(node)
based on the actualy regop that node points at.
check_reg_nextoper implements *checking* that what NEXTOPER(node)
would return is the same as what reg_nextoper would produce.

Simplify the logic of the loop so that we do not have to deal with things like
"While that was not END last time...", use a constant var for op, and remove
unnecessary (U8) casts that just clutter up the code.

regcomp.c - in Perl_regprop show the capture buffer data we just added
BRANCH, BRANCHJ, and TRIE and TRIEC nodes now store the how many capture
buffers OPEN opcodes (and logical equivalents) were defined BEFORE them.
This adds diagnostic output to Perl_regprop() so this data can be seen
in the dump.
Current notation is "(buf: %d)", this might change in the future.

regcomp.c - debug output changes to be less cluttered
The output of use 're' debug was getting very difficult to
understand. This patches declutters the output by removing
most redundant data about the next regop that would be processed
following a given regop. Only when the "next" regop data would
*differ* from the "following regnode" is it shown. When it /is/
shown it is not shown in parenthesis but with an arrow notation.
Previous to this patch we might get output like this:
Compiling REx "foo(?:[Bb]ar|fop)*baz"
Final program:
1: EXACT <foo> (3)
3: CURLYM[0]{0,INFTY} (16)
5: BRANCH (buf:0) (10)
6: ANYOFM[Bb] (8)
8: EXACT <ar> (14)
10: BRANCH (buf:0) (FAIL)
11: EXACT <fop> (14)
13: TAIL (14)
14: SUCCEED (0)
15: NOTHING (16)
16: EXACT <baz> (18)
18: END (0)
After this patch we get more readable (IMO) output like this:
Compiling REx "foo(?:[Bb]ar|fop)*baz"
Final program:
1: EXACT <foo>
3: CURLYM[0]{0,INFTY} -> 18
5: BRANCH (buf:0) -> 11
7: ANYOFM[Bb]
9: EXACT <ar> -> 16
11: BRANCH (buf:0) -> FAIL
13: EXACT <fop> -> 16
15: TAIL
16: SUCCEED.
17: NOTHING
18: EXACT <baz>
20: END.
Transitions to 0, which really mean that the regop is an "END" type
regop are indicated by a full stop. Non linear transitions or
transitions to a regop that is not the physical successor to the
"current" regnode are shown as -> %d, or -> FAIL for fail case branches.
Notice the difference between
5: BRANCH (buf:0) (10)
5: BRANCH (buf:0) -> 11
