There's still a problem with this patch (even with the other fixes I
made to it), it's not loading profiles with multiple hats properly:

  $ cat /tmp/example_profile
  /tests/regression/apparmor/changehat {

    ^sub {
      /proc/*/attr/current w,
      /tmp/sdtest.1713-15650-z0Mlub/file2 rw,
    }

    ^sub2 {
      /proc/*/attr/current w,
      /tmp/sdtest.1713-15650-z0Mlub/file2 rw,
    }

    ^sub3 {
      /proc/*/attr/current w,
      /tmp/sdtest.1713-15650-z0Mlub/file2 rw,
    }
  }

  $ sudo ./apparmor_parser /tmp/example_profile

  $ sudo grep changehat /sys/kernel/security/apparmor/profiles
  /tests/regression/apparmor/changehat (enforce)
  /tests/regression/apparmor/changehat//sub (enforce)

Rebuilding the parser with debugging enabled for just parser_interface.c
(via 'make clean all && rm parser_interface.o && make parser_interface.o && make')
gives the following output when loading the profile:

  $ sudo ./apparmor_parser /tmp/example_profile
  parser: Serializing policy for /tests/regression/apparmor/changehat.
  parser: Writing name 'version'
  parser: Writing name 'profile'
  parser: Writing name '(null)'
  parser: Writing name 'flags'
  parser: Writing name 'caps64'
  parser: Writing name 'aadfa'
  parser: Serializing policy for sub.
  parser: Writing name 'version'
  parser: Writing name 'profile'
  parser: Writing name '(null)'
  parser: Writing name 'flags'
  parser: Writing name 'caps64'
  parser: Writing name 'aadfa'

I'm not sure why it's only picking out the first of the hats.
