ffccfd2 x86_64 assembly optimization for scalar_4x64 (Pieter Wuille)

Gregory Maxwell 34b898dc84 Additional comments for the testing PRNG and a seeding fix. 
Rw has additional short-cycle inputs because 2^32/0x464fffff >= 2.

Gregory Maxwell 4be8d6fc42 Centralize the definition of uint128_t and use it uniformly. 
This needs to be renamed along with the other _t types, because _t
 is reserved.  But that will be done later.

Gregory Maxwell 25b35c7ecb Convert field code to strict C89 (+ long long, +__int128) 
This makes the software more portable to embedded systems
 and static analysis tools.

Sadly, it can't result in identical binaries because C99 mixed
 declarations seem to make GCC emit superfluous stack-pointer
 updates. The compiler is also somewhat dependent on the
 declaration order.

Gregory Maxwell 70ae0d2851 Use secp256k1_fe_equal_var in secp256k1_fe_sqrt_var. 
In theory this should be faster, since secp256k1_fe_equal_var is able to
 shortcut the normalization.  On x86_64 the improvement appears to be in
 the noise for me.  At least it makes the code cleaner.
