[RFC PATCH] audit: generic compat system call support

[AKASHI Takahiro]

Arm64 supports 32-bit mode(AArch32) and 64-bit mode(AArch64).
To enable audit support, we want to avoid duplicating lib/audit.c
as other arch's do, and instead to use lib/audit.c and extend/re-work it 
in order to support compat system calls as well.

Changes are nothing fancy, just copying lib/audit.c and adding hooks
for compat system calls as done in other arch's.

Once this patch is accepted, my aarch64 patch will be rebased on top
of this.
(If you want, I can submit it immediately because it is already working.)
