1f338f7078 nwztools/upgtools: add support for windows
In order to avoid the crypto++ mess, the code uses the Windows Cryptography API,
which is standard. There is also some makefile magic to cross-compile:
  make PREFIX=i686-w64-mingw32- EXE_EXT=.exe
I selected the option so that it should statically link supports libraries used
by gcc (slsj and libwinpthread).

37f95f67fe nwztools/upgtools: rewrite keysig brute force search
The new search has two new features:
- it takes advantage of the fact that DES keys are only 56-bit long (and not 64)
- it is now multithreaded
As a proof of concept, I ran it on the A10 series firmware upgrade and was able
to find the key in a few seconds using 4 threads. The search is still limited
to ascii hex passwords (seems to work on all devices I have tried thus far).

cf82f208e3 nwztools: cleanup the code
There was a lot of copy and paste, and the code was just crap. This commit tries
to clarify the code and also document the encryption procedure. Hopefully I didn't
break anything.
