[RFC PATCH 0/5] Cleanup code in and around audit_expand()

The recent audit match overflow patches caused me to take a closer look
at audit_expand() and how it is used, which unsurprisingly revealed a
number of things that we could do a bit better.  This patchset is the
result of that and aims to cleanup some of the ugliness while also
making the code a bit more robust.

Currently a RFC pending some closer self-review, but the patchset
compiles, boots, and passes the audit-testsuite and selinux-testsuite
cleanly.

      audit: only call audit_expand() once in audit_log_vformat()
      audit: convert audit_expand() to operate in multiples of
         AUDIT_BUFSIZ
      audit: move from a size_t buffer length to an int buffer length
      audit: add a missing function definition when !CONFIG_AUDIT
      audit: drop BUG_ON() from audit_log_XXX()
