Added double for points in Jacobian coordinates.

scalar_mult based on Jacobian representation
...
This version of scalar_mult should be faster and much better
against side-channel attacks. Except bn_inverse and bn_mod
all functions are constant time. bn_inverse is only used
in the last step and its input is randomized. The function
bn_mod is only taking extra time in 2^32/2^256 cases, so
in practise it should not occur at all. The input to bn_mod
is also depending on the random value.
There is secret dependent array access in scalar_multiply,
so cache may be an issue.

Make scalar_multiply timing attack safe.
...
This should make side-channel attacks much more difficult. However,
1. Timing of bn_inverse, which is used in point_add depends on input.
2. Timing of reading secp256k1_cp may depend on input due to cache.
3. The conditions in point_add are not timing attack safe.
However point_add is always a straight addition, never double or some
other special case.
In the long run, I would like to use a specialized point_add using Jacobian
representation plus a randomization when converting the first point to
Jacobian representation. The Jacobian representation would also make
the procedure a bit faster.
