This patch adds the creation of an implicit set variable
@{profile_name} for use within policy. It expands to:
- a given profile name if specified; e.g. for
'profile flappy_bird /some/pattern/match* { [...] }'
@{profile_name} would expand to 'flappy_bird'
- if no given name, the match pattern; e.g. for
'/usr/bin/doge_bird { [...] }'
@{profile_name} would expand to '/usr/bin/doge_bird'
- hats and child profiles will include the fully qualified name; e.g.
the 'doge' hat in the /usr/bin/flappy_bird profile would cause
@{profile_name} to expand to '/usr/bin/flappy_bird//doge' within the
'doge' hat, and '/usr/bin/flappy_bird' outside of it in the profile.
There are some parsing tests added, but more tests are needed to verify
that expansion occurs properly (I've verified manually using parser
dumps of the added tests, but automated checks are needed).
The @{profile_name} variable is expected to be most useful in the
context of signal and ptrace rules (e.g. for specifying that an app
can send itself signals).

This patch adds the newer rules class entries (e.g. ptrace, signals)
when dumping profiles (invoking the parser with the -dd argument).

This cleans things up a bit and fixes a bug where not all rules are
getting properly counted so that the addition of policy_mediation
rules fails to generate the policy dfa in some cases.
Because the policy dfa is being generated correctly now we need to
fix some tests to use the new -M flag to specify the expected features
set of the test.

This will simplify add new features as most of the code can reside in
its own class. There are still things to improve but its a start.

When compiling the parser, g++ currently emits warnings like so:
profile.h: In constructor ‘Profile::Profile()’:
profile.h:177:11: warning: missing initializer for member ‘aa_rlimits::limits’ [-Wmissing-field-initializers]
rlimits = { 0 };
^
This patch fixes the issue.

Convert the codomain to a class, and the policy lists that store
codomains to stl containers instead of glibc twalk.
