Our simple language tests did not include any file deny rule tests. This
patch adds a few simple ones.

let allow be used as a prefix in place of deny. Allow is the default
and is implicit so it is not needed but some user keep tripping over
it, and it makes the language more symmetric
eg.
/foo rw,
allow /foo rw,
deny /foo rw,
Patch history:
v1: - initial revision
v2: - rename yacc target rule from opt_deny to opt_perm_mode to
reflect
that it can be either an allow or deny modifier
- break apart tests into more digestible chunks and to clarify
their purpose
- fix some tests to exercise 'audit allow'
- add negative tests for 'allow' and 'deny' in the same rule
- add support for 'allow' keyword to apparmor.vim
- fix a bug in apparmor.vim to let it recognize multiple
capability entries in a single line.
v3: - add support for optional keywords on capability rules in
regression tests, as well as the bare capability keyword (via
'cap:ALL')
- add allow, deny, and conflicting capability behavioral
regression tests
- fix vim syntax modeline to refer to apparmor in parser tests
- adjust FILE regex in vim syntax file creator script

Add the optional 'file' keyword to the language/grammer. The main reason
for doing this is to support false token injection. Which is needed
to move towards the parser being broken out into an api that can be
used to parse individual rule types, separate from parsing the whole file.
Since we are adding the token to the grammar expose it to userspace with
the 'file' keyword. While not needed it helps bring consistency, as all
the other rule types start with a keyword (capability, network, rlimit, ...).
Also allow the bare keyword to be used to represent allowing all file
operations, just as with network and capability. Domain transitions are
defaulted to ix. Thus
file,
is equivalent to
/** rwlkmix,
