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

the out-of-bounds read when 8192 bytes are copied from the string.
