[PATCH] auxiliary vector cleanups

Browse Source 
The size of auxiliary vector is fixed at 42 in linux/sched.h.  But it isn't
very obvious when looking at linux/elf.h.  This patch adds AT_VECTOR_SIZE
so that we can change it if necessary when a new vector is added.

Because of include file ordering problems, doing this necessitated the
extraction of the AT_* symbols into a standalone header file.
