Bignum Mod: remove endianness from modulus

The external representation before included more than just endianness
(like reading in Mongtomery curve scalars or converting hashes to
numbers in a standard compliant way).
These are higher level concepts and are out of scope for Bignum and for
the modulus structure.

(like reading in Mongtomery curve scalars or converting hashes to

These are higher level concepts and are out of scope for Bignum and for

Add merge slots to Bignum files
...
Legacy Bignum is excluded as it doesn't get regular extensions like new
ones.
Each slot uses comments of their respective filetype. Since .data files
don't have a syntax for comments, dummy test cases are used. (These test
cases will never be executed and no noise will be added to tests.)

Bignum: Apply naming conventions
...
Numbers:
- A, B for mbedtls_mpi_uint* operands
- a, b for mbedtls_mpi_uint operands
- X or x for result
- HAC references where applicable
Lengths:
- Reserve size or length for length/size in bytes or byte buffers.
- For length of mbedtls_mpi_uint* buffers use limbs
- Length parameters are qualified if possible (eg. input_length or
a_limbs)
Setup functions:
- The parameters match the corresponding structure member's name
- The structure to set up is a standard lower case name even if in other
functions different naming conventions would apply
Scope of changes/conventions:
- bignum_core
- bignum_mod
- bignum_mod_raw
