Fix backward incompatibility revolving around OSSL_HTTP_REQ_CTX_sendreq_d2i()
The OSSL_HTTP_REQ_CTX API has a few changes compared to the older
OCSP_REQ_CTX API which are not quite obvious at first sight.
The old OCSP_REQ_CTX_nbio_d2i() took three arguments, of which one is
an output argument, and return an int, while the newer
OSSL_HTTP_REQ_CTX_sendreq_d2i() returns the value directly and thereby
takes one less argument.

Fix the RSA_SSLV23_PADDING padding type
This also fixes the public function RSA_padding_check_SSLv23.
Commit 6555a89 changed the padding check logic in RSA_padding_check_SSLv23
so that padding is rejected if the nul delimiter byte is not immediately
preceded by at least 8 bytes containing 0x03. Prior to that commit the
padding is rejected if it *is* preceded by at least 8 bytes containing 0x03.
Presumably this change was made to be consistent with what it says in
appendix E.3 of RFC 5246. Unfortunately that RFC is in error, and the
original behaviour was correct. This is fixed in later errata issued for
that RFC.
This has no impact on libssl for modern versions of OpenSSL because
there is no protocol support for SSLv2 in these versions. However
applications that call RSA_paddin_check_SSLv23 directly, or use the
RSA_SSLV23_PADDING mode may still be impacted. The effect of the original
error is that an RSA message encrypted by an SSLv2 only client will fail to
be decrypted properly by a TLS capable server, or a message encrypted by a
TLS capable client will fail to decrypt on an SSLv2 only server. Most
significantly an RSA message encrypted by a TLS capable client will be
successfully decrypted by a TLS capable server. This last case should fail
due to a rollback being detected.

this issue.

Fix Null pointer deref in X509_issuer_and_serial_hash()
The OpenSSL public API function X509_issuer_and_serial_hash() attempts
to create a unique hash value based on the issuer and serial number data
contained within an X509 certificate. However it fails to correctly
handle any errors that may occur while parsing the issuer field (which
might occur if the issuer field is maliciously constructed). This may
subsequently result in a NULL pointer deref and a crash leading to a
potential denial of service attack.
The function X509_issuer_and_serial_hash() is never directly called by
OpenSSL itself so applications are only vulnerable if they use this
function directly and they use it on certificates that may have been
obtained from untrusted sources.

.md extension was a natural step, switching to mixed cases was not
a change to the better, it gives them a ragged appearance:
Moreover, the NOTES-Windows.txt file is the only file which has been
converted to markdown but has received a .txt file extension.
This doesn't make sense, because the OpenSSL users on Windows will
need to read the other markdown documents as well. Since they are
developers, we can trust them to be able to associate their favorite
editor with the .md extension.
In fact, having a comment at the beginning of the file saying that it
is in markdown format but we didn't dare to add the correct extension
in order not to overwhelm our Windows users can be interpreted either
as unintentionally funny or disrespectful ;-)
