Garbling library based on JustGarble.

This code is still in alpha and the API is not yet fully stable (as in, future commits may change it). However, I'd love to hear feedback from anyone who uses it, to help improve the library.

Run the following:

autoreconf -i
./configure
make
sudo make install

This installs two libraries: libgarble for actually garbling and evaluating a circuit, and libgarblec for writing circuits.

To test, run the following:

cd test
make aes
./aes

This will garble and evaluate an AES circuit, and present timings in cycles/gate.
