23f6784297 Use unsigned comparisons. Prior to this commit, SHA1_Update and
RIPEMD160_Update were broken when all of the following conditions
applied:
(1) The platform is i386.
(2) The program calling *_Update is statically linked to libmd.
(3) The buffer provided to *_Update is aligned modulo 4 bytes.
(4) The buffer extends beyond 2GB.

Due to the design of this code, SHA1_Update and RIPEMD160_Update will
still be broken if conditions (1)-(3) apply AND the buffer extends
beyond 4GB (i.e., there is an integer overflow in computing "data + len").
Since this remaining bug simply replaces SIGSEGV with a bogus hash (and
non-broken programs should never provide such operands) I don't consider
it to be a serious problem.

5c3a55dea7 Backed out rev.1.6 and subsequent copying of it (bogus addition of
-static to CFLAGS).  It just turned rev.1.5 into an obfuscated no-op.
As explained in the log for rev.1.5, testing should be done in the
host environment but there is a problem in cross-compilation environments.
As not explained in the log for rev.1.6, there was apparently a practical
problem with cross-compiling (makeworld should have set -static in
LDFLAGS but apparently didn't).  Cross-compilation was especially
complicated because the relevant programs are test programs that were
run at beforeinstall time -- dynamic libraries might or might not exist
depending on the build options.  The complications became moot in
rev.1.8 when beforeinstall was renamed "test".

41d8423f71 Stage 3 of dynamic root support. Make all the libraries needed to run
binaries in /bin and /sbin installed in /lib. Only the versioned files
reside in /lib, the .so symlink continues to live /usr/lib so the
toolchain doesn't need to be modified.

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

af03a3cbd6 Improve the handling of Encode and Decode operations in MD5.
Use memcpy for all little-endian architectures, sys/kern/md5c.c indicates
this should be safe for all currently supported LE archs.

Change the Encode and Decode functions for other archs to use le32toh()
and htole32() functions instead of explicit byte shuffling.

On sparc64 this gives md5(1) about 8% speed increase.

is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.
