updated dates on files that have actually changed this year. This makes
the diff across versions readable again.

but might as well keep it up to date. And it's easier to do it once with
a 'perl -pi' command than to update each file over time.
Apologies to anyone looking at diffs.

Where loadstor.h was needed but only implicitly included via bit_ops.h,
include it directly
Add endian reversal functions to bit_ops.h
Remove some unneeded includes in big_ops2.cpp and a few other files.

into
account endian differences.
The current code does not take advantage of the knowledge of which endianness
we are running on; an optimization suggested by Yves Jerschow is to use (unsafe)
casts to speed up the load/store operations. This turns out to provide large
performance increases (30% or more) in some cases.
Even without the unsafe casts, this version seems to average a few percent
faster, probably because the longer loading loops have been partially or
fully unrolled.
This also makes the code implementing low-level algorithms like ciphers and
hashes a bit more succint.

caller. The resulting code is longer and somewhat harder to read, but it's
giving 25-30% performance increases on my Core2, and something a bit
lower but still measurable on the P4.
