'RELENG_4_2_0_RELEASE'.

This commit was manufactured to restore the state of the 4.2-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Zap SHA1 password support. This will be re-implemented at a later date.

Big code cleanup. (Inspired by Brandon Gillespie). Also move as

much as possible away from secure/ to make extending easier.

The new crypt code broke "make world". Back it out.

Rewrite of crypt library to be more modular, and addition of the

Secure Hashing Algorithm - 1 (SHA-1), along with the further
refinement of what $x$salt$hash means.  With this new crypt the
following are all acceptable:

    $1$
    $MD5$
    $SHA1$

Note: $2$ is used by OpenBSD's Blowfish, which I considered adding
as $BF$, but there is no actual need for it with SHA-1.  However,
somebody wishing to add OpenBSD password support could easilly add
it in now.

There is also a malloc_crypt() available in the library now, which
behaves exactly the same as crypt(), but it uses a malloced buffer
instead of a static buffer.  However, this is not standard so will
likely not be used much (at all).

Also, for those interested I did a brief speed test Pentium 166/MMX,
which shows the DES crypt to do approximately 2640 crypts a CPU second,
MD5 to do about 62 crypts a CPU second and SHA1 to do about 18 crypts
a CPU second.
