This reverts commit 62c5901f0a5061a8825e19c77f88c91fea235078.

Reverting commit due the macros are meant to be local and not following the
naming convention.

23bdeca64d Add core constant time comparison 
Unfortunately reusing the new function from the signed constant time
comparison is not trivial.

One option would be to do temporary conditional swaps which would prevent
qualifying input to const. Another way would be to add an additional
flag for the sign and make it an integral part of the computation, which
would defeat the purpose of having an unsigned core comparison.

Going with two separate function for now and the signed version can be
retired/compiled out with the legacy API eventually.

The new function in theory could be placed into either
`library/constant_time.c` or `library/bignum_new.c`. Going with the
first as the other functions in the second are not constant time yet and
this distinction seems more valuable for new (as opposed to belonging to
the `_core` functions.

91dc67d31c Allow (NULL, 0) as a representation of 0 
- We don't check for NULL pointers this deep in the library
- Accessing a NULL pointer when the limb number is 0 as a mistake is the
  very similar to any other out of bounds access
- We could potentially mandate at least 1 limb representation for 0 but
  we either would need to enforce it or the implementation would be less
  robust.
- Allowing zero limb representation - (NULL, 0) in particular - for zero
  is present in the legacy interface, if we disallow it, the
  compatibility code will need to deal with this (more code size and
  opportunities for mistakes)

In summary, interpreting (NULL, 0) as the number zero in the core
interface is the least of the two evils.

f1d617deb8 Add tests for big endian core I/O 
The test case where there were extra limbs in the MPI failed and this
commit contains the corresponding fix as well. (We used to use the
minimum required limbs instead of the actual limbs present.)
