https://boringssl-review.googlesource.com/31085 wasn't right. We already forbid
creating BN_MONT_CTX on negative numbers, which means almost all moduli already
don't work with BN_mod_exp_mont. Only -1 happened to not get rejected, but it
computed the wrong value. Reject it instead.
Update-Note: BN_mod_exp* will no longer work for negative moduli. It already
didn't work for all negative odd moduli other than -1, so rejecting -1 and
negative evens is unlikely to be noticed.

This often causes confusion since, for various silly reasons (intrinsic
ref-counting, FOO_METHOD, and RSA's cached Montgomery bits), the thread
safety of some functions don't match the usual const/non-const
distinction. Fix const-ness where easy and document it otherwise.

Historically, OpenSSL's modular exponentiation functions tolerated negative
moduli by ignoring the sign bit. The special case for a modulus of 1 should do
the same. That said, this is ridiculous and the only reason I'm importing this
is BN_abs_is_word(1) is marginally more efficient than BN_is_one() and we
haven't gotten around to enforcing positive moduli yet.
Thanks to Guido Vranken and OSSFuzz for finding this issue and reporting to
OpenSSL.

This fixes uninitialized memory read reported by Nick Mathewson in
https://github.com/openssl/openssl/issues/6347.
It imports the memset from upstream's 2c739f72e5236a8e0c351c00047c77083dcdb77f,
but I believe that fix is incorrect and instead RC4 shouldn't be allowed in
this context. See
https://github.com/openssl/openssl/pull/6603#issuecomment-413066462 for
details.
Update-Note: Decoding a password-protected PEM block with RC4 will, rather than
derive garbage from uninitialized memory, simply fail. Trying to encode a
password-protect PEM block with an unsupported cipher will also fail, rather
than output garbage (e.g. tag-less AES-GCM).

Chromium actually passes -flto=thin, which seems to avoid the error, testing

EVP_MD_CTX_init (and EVP_MD_CTX_cleanup) are those buried in
bssl::ScopedEVP_MD_CTX. However, not all calls are problematic, only the one in

if the input file contains a '\' then the Go code thinks that it counts
