[apparmor] [PATCH 0/6] parser: Fix mount option parsing bugs

[Tyler Hicks]

This patch set fixes a handful of bugs surrounding mount rule parsing.
Primarily, the bugs are around the parsing of mount options.

The last patch adds a bunch of parser tests to make sure that valid
options are accepted and invalid options are rejected.

With all 6 patches applied, the parser's make check target passes as
well as the regression tests.
