From: Taahir Ahmed <ahmed.taahir@xxxxxxxxx>
utils/key2pub.py can now be run under either python 2.7 or python 3.x.
This required some minor syntactical changes as well as switching from
M2Crypto to pycrypto, since M2Crypto doesn't support python 3.x.
In addition, some errors in the generated source file keys-ssl.h are
fixed:
* The correct OpenSSL header for BN_ULONG is included.
* The generated constants are given the 'ull' suffix to prevent
warnings about constants that are too large.
