These can be used to invert values in ECDSA. Unlike their BIGNUM
counterparts, the caller is responsible for taking values in and out of
Montgomery domain. This will save some work later on in the ECDSA
computation.

This was primarily for my own understanding, but this should hopefully
also be clearer and more amenable to using unsigned indices later.

It always returns one, so just void it.

This is an OpenSSL thing to support platforms where BN_ULONG is not
actually the size it claims to be. We define BN_ULONG to uint32_t and
uint64_t which are guaranteed by C to implement arithemetic modulo 2^32
and 2^64, respectively. Thus there is no need for any of this.

crypto/{asn1,x509,x509v3,pem} were skipped as they are still OpenSSL
style.

This isn't all of our pointer games by far, but for any code which
doesn't run on armv6, memcpy and pointer cast compile to the same code.
For code with does care about armv6 (do we care?), it'll need a bit more
work. armv6 makes memcpy into a function call.
Ironically, the one platform where C needs its alignment rules is the
one platform that makes it hard to honor C's alignment rules.
