Closes#12129
As described in https://github.com/openssl/openssl/issues/12129 the
readability of the internal functions providing the two alternative
implementations for `BN_mod_inverse()` is a bit lacking.
Both these functions are now completely internal, so we have the
flexibility needed to slightly improve readability and remove
unnecessary NULL checks.
The main changes here are:
- rename `BN_mod_inverse_no_branch()` as `bn_mod_inverse_no_branch()`:
this function is `static` so it is not even visible within the rest of
libcrypto. By convention upcase prefixes are reserved for public
functions.
- remove `if (pnoinv == NULL)` checks in `int_bn_mod_inverse()`: this
function is internal to the BN module and we can guarantee that all
callers pass non-NULL arguments.
- `bn_mod_inverse_no_branch()` takes an extra `int *pnoinv` argument, so
that it can signal if no inverse exists for the given inputs: in this
way the caller is in charge of raising `BN_R_NO_INVERSE` as it is the
case for the non-consttime implementation of `int_bn_mod_inverse()`.
- `BN_mod_inverse()` is a public function and must guarantee that the
internal functions providing the actual implementation receive valid
arguments. If the caller passes a NULL `BN_CTX` we create a temporary
one for internal use.
- reorder function definitions in `crypto/bn/bn_gcd.c` to avoid forward
declaration of `static` functions (in preparation for inlining).
- inline `bn_mod_inverse_no_branch()`.

BSD-generic32 already uses this for building shared libraries on other
32-bit BSD platforms. Commit b7efa56 collapsed various *BSD targets
down to the BSD-generic ones and BSD-x86. At the time only
OpenBSD/i386 used `bsd-shared` while both FreeBSD and NetBSD used
`bsd-gcc-shared`. In practice, all of the BSDs are using either a
GCC/ld.bfd toolchain or a clang/lld toolchain both of which are
compatible with 'bsd-gcc-shared'.
Retire 'bsd-shared' since this removes the last user.
Fixes#12050.

why it is no longer working.

Before 3.0 is released, the names are mutable and this prevents more

Just the renaming and a little reformatting.

The newer RSA sp800-56b algorithm is being used for the normal case of a non multiprime key of at least length 2048.
Insecure key lengths and mutltiprime RSA will use the old method.
Bad public exponents are no longer allowed (i.e values less than 65537 or even). Values such as 2 that would cause a infinite loop now result in an error. The value of 3 has been marked as deprecated but is still allowed for legacy purposes.
