...
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.

Add a reference consistency test to ge_tests.

This adds all points used in the test together in random order, which
should result in infinity.
