First cut at RSA decryption/signature using the Chinese Remainder
Theorem. Not yet tested, and given the number of moving parts I would
be astonished if this version actually worked, but it does compile.
Added some timing code to tests/test-rsa.c so we can see whether this
is doing anything useful once it does work.
