Gianluca Guida b6cbf7203b Import unmodified NetBSD libc in trunk
This patch imports the unmodified current version of NetBSD libc.
The NetBSD includes are in /nbsd_include, while the libc code itself is 
split between lib/nbsd_libc and common/lib/libc.

# Note: The atomic operations here in these assembly files are atomic
# only with respect to regular memory on uniprocessor systems. Since
# we don't support any MP m68k systems, this is just fine. If we ever
# do, then these routines will probably need to be replaced with CAS-
# based routines (CAS generates an atomic bus cycle, whereas these
# others are merely single-instruction).
