Some math deprecations
Mostly things that shouldn't be used (like almost Montgomery inverse,
which isn't even constant time) or are very much just for internals
(like the word-wise Montgomery inverse computation used for reduction).
Make variable time division explicit; leaves plain divide as a call
but it forwards to ct_divide now. All callers within the library are
now explicitly consttime or vartime.
Add a shortcut for modulus by one word - this hits quite often
especially in the ECC code
