Adds a stub for a function that will return the AUDIT_ARCH_* value
appropriate to the supplied task based on the system call convention.
For audit's use, the value can generally be hard-coded at the
audit-site. However, for other functionality not inlined into syscall
entry/exit, this makes that information available. seccomp_filter is
the first planned consumer and, as such, the comment indicates a tie to
CONFIG_HAVE_ARCH_SECCOMP_FILTER.

Only 32 bits of system call number are meaningful, so make the
specification for syscall_get_nr() be to return int, not long.

This adds asm-generic/syscall.h, which documents what a real
asm-ARCH/syscall.h file should define. This is not used yet, but will
provide all the machine-dependent details of examining a user system call
about to begin, in progress, or just ended.
Each arch should add an asm-ARCH/syscall.h that defines all the entry
points documented in asm-generic/syscall.h, as short inlines if possible.
This lets us write new tracing code that understands user system call
registers, without any new arch-specific work.
