John Johansen 94632cdca5 Unify escape sequence processing into a set of library fns.
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
