Linus Torvalds cef661fc79 Add support for alternate SHA1 library implementations.
This one includes the Mozilla SHA1 implementation sent in by Edgar Toernig.
It's dual-licenced under MPL-1.1 or GPL, so in the context of git, we
obviously use the GPL version. 

Side note: the Mozilla SHA1 implementation is about twice as fast as the
default openssl one on my G5, but the default openssl one has optimized
x86 assembly language on x86. So choose wisely.

# -DCOLLISION_CHECK if you believe that SHA1's
# 1461501637330902918203684832716283019655932542976 hashes do not give you
# enough guarantees about no collisions between objects ever hapenning.
#
# -DNSEC if you want git to care about sub-second file mtimes and ctimes.
# Note that you need some new glibc (at least >2.2.4) for this, and it will
# BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely randomly
# break unless your underlying filesystem supports those sub-second times
# (my ext3 doesn't).
