Manuel Pégourié-Gonnard c9e387ca9e Optimize ecp_modp() 
Makes it 22% faster, for a 5% gain on ecp_mul()

Manuel Pégourié-Gonnard d1e7a45fdd Rework ecp_mod_p192() 
On x86_64, this makes it 5x faster, and ecp_mul() 17% faster for this curve.
The code is shorter too.

From kernel objects at msdn:
    Kernel object handles are process specific. That is, a process must either create the object or open an existing object to obtain a kernel object handle. The per-process limit on kernel handles is 2^24.

Windows Internals by Russinovich and Solomon as well says that the high bits are zero.
