Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.
This makes /lib being populated again.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

Introduce further adjustments to the renaming of libmd
symbols: make sure that we do not generate dangling weak
aliases, as this causes build failures on MIPS.

(Makefile.inc1): add dependency of xinstall on libmd to
avoid failure of parallel bootstrap.
(lib/libmd/*.h): do not redefine symbols if already
defined as macros (libcrypt uses the same sources internally,
redefining symbols with a prefix of its own).
Fixes build failures caused by previous change to libmd.

Add a prefix to all symbols in libmd to avoid incompatibilites
with same-named, but not binary compatible, symbols from libcrypto.
Also introduce Weak aliases to avoid the need to rebuild dependent
binaries and a major version bump.

my tests, it is faster ~20%, even on an old IXP425 533MHz it is ~45%
faster... This is partly due to loop unrolling, so the code size does
significantly increase... I do plan on committing a version that
rolls up the loops again for smaller code size for embedded systems
where size is more important than absolute performance (it'll save ~6k
code)...
The kernel implementation is now shared w/ userland's libcrypt and

We drop support for sha256 from sha2.c, so now sha2.c only contains

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.

-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".

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()

On sparc64 this gives md5(1) about 8% speed increase.
Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also

Things like md5(1) where speed is critical should still link with libmd.a,

not worth the hassle.
