Checked in.

That also means we don't have to add a bunch of configure-script gunk to
check for the library, and don't have to require people to install the
library in question to get the decryption.

So does the UNIX Makefile. :-)  I checked in changes to Makefile.am and
Makefile.nmake, in addition to the patch and the new crypt-XXX.[ch]
files; take a look at those changes to see what's necessary on UNIX and
Win32.  (Note that you need to mention the header files on UNIX;
otherwise, "make dist" won't put them into the source tarball for a
release.)
