mix patches for OpenBSD (was Re: [Remops] Re: FC: Anonymous remailer op offline)

[Nomen Nescio]

Are one or both of these still necessary?

----- CUT HERE ------------

Mixmaster 2.9b23 still searches for opensslv.h in a nonexistent
/usr/include/ssl/openssl directory on OpenBSD 2.6 and 2.7.  The patch to
the Install routine below hopefully fixes the hardcoded directory in a
manner that does not break on other OSes.

Also, OpenBSD's OpenSSL installation lacks the patented IDEA routines. 
Copy OpenSSL's i_cbc.c, i_cfb64.c, i_skey.c, idea.h, and idea_lcl.h to
Src.  The patch to the Makefile.in below adds them to the build.

OpenSSL versions are actually hexadecimal numbers, though in the past we
have been OK using them as decimals for comparison, at least in release
versions.

Now, we are using them as hexadecimal numbers to encode beta vs final
status.  This breaks Mixmaster 2.9's Install script.

The patch below fixes the version comparison so it should work with
future OpenSSL versions as well.

/* Numeric release version identifier:
 * MMNNFFPPS: major minor fix patch status
 * The status nibble has one of the values 0 for development, 1 to e for betas
 * 1 to 14, and f for release.  The patch level is exactly that.
 * For example:
 * 0.9.3-dev      0x00903000
 * 0.9.3-beta1    0x00903001
 * 0.9.3-beta2-dev 0x00903002
 * 0.9.3-beta2    0x00903002 (same as ...beta2-dev)
 * 0.9.3          0x0090300f
 * 0.9.3a         0x0090301f
 * 0.9.4          0x0090400f
 * 1.2.3z         0x102031af
 *
 * For continuity reasons (because 0.9.5 is already out, and is coded
 * 0x00905100), between 0.9.5 and 0.9.6 the coding of the patch level
 * part is slightly different, by setting the highest bit.  This means
 * that 0.9.5a looks like this: 0x0090581f.  At 0.9.6, we can start
 * with 0x0090600S...
 *
 * (Prior to 0.9.3-dev a different scheme was used: 0.9.2b is 0x0922.)
 * (Prior to 0.9.5a beta1, a different scheme was used: MMNNFFRBB for
 *  major minor fix final patch/beta)
