Log message:
Rewrite and simplify BN_MONT_CTX_set()
OpenSSL commit 4d524040bc8 changed BN_MONT_CTX_set() so that it computed
a 64 bit N^-1 on both BN_BITS2 == 32 and BN_BITS2 == 64 platforms. However,
the way in which this was done was to duplicate half the code and wrap it
in #ifdef.
Rewrite this code to use a single code path on all platforms, with #ifdef
being limited to setting an additional word in the temporary N and storing
the result on BN_BITS2 == 32 platforms. Also remove stack based BIGNUM in
favour of using the already present BN_CTX.
