[CryptoAPI-devel] docs updated, findpatch.pl added

[David B. <db...@du...>]

Committed my first patches/findpatch.pl addition to the make
patch-kernel/unpatch-kernel stuff.  The script looks at the kernel
version of the kernel to be patched, then attempts to locate the patch
of the closest version, it's not very smart right now.
For example if you have kernel version 2.4.17, and there are patches for
2.4.16 and 2.4.18 it will always choose the higher patch.  I'll most
likely change this to find the patch with the least distance numerically
from the kernel version.
  Anyway, also updated the Makefile to include this at the end of the
patch-kernel and unpatch-kernel instructions.
./kernel/Documentation/cryptoapi/cryptoloop.txt has also been updated to
explain a bit about how loopback fs encryption works, and there is a
section on how to use cryptoapi if you are migrating from loop-AES.
  also, it turns out apache is lame and doesn't list README files, even
if you appent .txt to them.  So those of you that looked at my docs
earlier please go back and check again, since the readme's i modified
are now up.  Figure out what we still need put in there so that it's
informative enough.
all for now!
