When the regex parser failed, the Chars objects created/used in rules
charset and cset_chars would not be cleaned up properly and would
leak.

With the exception of the documentation fixes, these should all be

MR: https://gitlab.com/apparmor/apparmor/-/merge_requests/687
This patch adjusts the bison grammer in libapparmor and the parser
to use the %define api.pure directive instead of the deprecated
%pure_parser and %pure-parser keywords. Bison had been warning about
the former:
libraries/libapparmor/src/grammar.y:71.1-12: warning: deprecated directive, use ‘%pure-parser’ [-Wdeprecated]
%pure_parser

Also for characters that are not recognized as a valid escape seq
make sure that the character is emitted.
previously
\$ resulted in \
where it should have been \$ if $ wasn't recognized

Fix the octal escape sequence that was broken, so that short escapes \0,
\00 \xa, didn't work and actually resulted in some encoding bugs.
Also we were missing support for the decimal # conversion \d123
Incorporate and update Steve Beattie's unit tests of escape sequences
patch
v2
- unify escape sequence processing, creating lib fns.
- address Steve Beattie's feedback
- incorporate Steve Beattie's feedback
v3
- address Seth's feedback
- add missing strn_escseq tests
- expand strn_escseq to take a 3rd parameter to allow specifying chars to
convert straight across. . eg "+" will cause it to convert \+ as +
- fix libapparmor/parse.y failed escape pass through to match processunqoted

The pcre parser in the dfa backend is not correctly converting escaped
hex string like
\0x0d
This is the minimal patch to fix, and we should investigate just using
the C/C++ conversion routines here.
I also I nominated for the 2.7 series.

Start of splitting regexp.y into logical components instead of the mess
it is today. Split out the expr-tree and parsing components from regexp.y
int expr-tree.x and parse.y and since regexp.y no longer does parsing
rename it to hfa.cc
Some code cleanups snuck their way into this patch and since I am to
lazy to redo it, I have left them in.
