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.

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.

Require that r and b are different for field multiplication.
...
Suggested by Peter Dettman, this prepares for slightly faster muitiplication
which writes results immediately to r before finishing reading b.

This should be whitespace/comment only changes and should produce the same

secp256k1_fe_sqrt checks for success
...
- secp256k1_fe_sqrt now checks that the value it calculated is actually a square root.
- Add return values to secp256k1_fe_sqrt and secp256k1_ge_set_xo.
- Callers of secp256k1_ge_set_xo can use return value instead of explicit validity checks
- Add random value tests for secp256k1_fe_sqrt
