This patch does the final consolidation of asm-*/resource.h file, without
changing any of the rlimit definitions on any architecture.  Primarily it
removes the __ARCH_RLIMIT_ORDER method and replaces it with a more compact
and isolated one that allows architectures to define only the offending
rlimits.

This method has the positive effect that adding a new rlimit can now be
purely done via changing asm-generic/resource.h alone.  Previously one
would have to patch 4 other (sparc, sparc64, alpha and mips) resource.h
files.

The patch also does style unification, whitespace cleanups and
simplification of resource.h files and cleans up the asm-generic/resource.h
file as well.  I've added more comments too.

This patch should have no effect on any code on any architecture.  (i.e.
it's a pure identity patch.)

Tested on x86 and carefully reviewed to make sure that Sparc, Sparc64,
MIPS and Alpha rlimits are still the same as required by the ABI.
