While some of these allocations will go away as we convert to C++,
some of these need to stay C as the are going to be moved into a
library to support loading cache from init daemons etc.
For the bits that will eventually be C++ this helps clean things up,
in the interim.
TODO: apply to libapparmor as well

Trunk commit 2456 broke the builds on i386 with the following compiler
error:
g++ -g -O2 -pipe -Wall -Wsign-compare -Wmissing-field-initializers -Wformat-security -Wunused-parameter -std=gnu++0x -D_GNU_SOURCE -DPACKAGE=\"apparmor-parser\" -DLOCALEDIR=\"/usr/share/locale\" -DSUBDOMAIN_CONFDIR=\"/etc/apparmor\" -I../libraries/libapparmor//include -c -o lib.o lib.c
lib.c: In function 'int strn_escseq(const char**, const char*, size_t)':
lib.c:236:47: error: no matching function for call to 'min(long unsigned int, size_t&)'
tmp = strntol(*pos, &end, 8, 255, min(3ul, n));
^
This is due to size_t differing in size on i386 and amd64. The
following patch addresses the issue by casting the constant values
to size_t (and removing the ul suffix since the constant values are
getting cast anyway), satisfying C++'s types (and the patch removes
the unnecessary min macro).

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 apparmor_parser has 3 different directory walking routines. Abstract
them out and use a single common routine.
