Rearrange the ARM backend

- Subject: Rearrange the ARM backend
This patch inlines elf32-arm.h into elfarm-oabi.c and elfarm-nabi.c,
and renames the latter to elf32-arm.c for consistency with other
targets. The only other changes are to the build system (to use the
new name) and to the copyright dates at the tops of the files (updated
to include the list from elf32-arm.h).
Tested using arm-elf and arm-oabi; both build, but the tests for
arm-oabi can't be run before or after. This is mostly because GAS
defaults to new abi unless -moabi is explicitly specified, so it can't
assemble anything. There's a similar problem in binutils/. I'm
confident this problem was already there before, and gas does appear to
work with -moabi (but I didn't check to see what state the results were
in).
I didn't try any of the possible cleanups; the biggest one would be to
remove all checks of OLD_ARM_ABI in elf32-arm.c. USE_REL could go away
too (although, CodeSourcery has a port that uses RELA for historical
reasons, so... but at least it's not oabi!).
OK? Any different preferences on how the inlining should be done?
