Make all the ELF relocation constants available.

BSD thinks you should only get the relocation constants for your target
architecture, but it's often useful to have them all available at once.
Rearrange the headers to enable that.

Also update the (modified) NetBSD files to CVS HEAD.

Also remove the unused BSDism R_TYPE.

libc: fix typo in __RENAME macro

Apparently __strncpy_real redirects to strcpy instead of strncpy for GCC
builds. This is bad, and it confused a project compiled by GCC that uses
strcpy.

I audited all of the FORTIFY-related __RENAMEs both manually and with a
script I hacked together; they all look correct aside from this one.

FWIW, with the cleaned up clang FORTIFY, lots of the `void foo()
__RENAME(foo)` will just become `void foo()` if this last thing I'm
working on gets through review.
