The old custom extensions API was not TLSv1.3 aware. Extensions are used
extensively in TLSv1.3 and they can appear in many different types of
messages. Therefore we need a new API to be able to cope with that.

This move prepares for the later addition of the new custom extensions
API. The context codes have an additional "SSL_" added to their name to
ensure we don't have name clashes with other applications.

Under UEFI build environment, we may encounter the OSSL_SSIZE macro
re-definition error in e_os2.h if any module call OpenSSL API directly
by including "openssl/xxxx.h" (caused by the predefined _WIN32/_WIN64
macro, which should have been un-defined under OPENSSL_SYS_UEFI).
Though it's not one recommended usage, this patch could still eliminate
the possible build issue by refining the OSSL_SSIZE definition under
OPENSSL_SYS_UEFI.

is replaced in the transcript with a special synthetic message_hash message
that just contains a hash of ClientHello1 as its message body.

conf has the ability to expand variables in config files. Repeatedly doing
this can lead to an exponential increase in the amount of memory required.
This places a limit on the length of a value that can result from an
expansion.

In TLSv1.3 the above messages signal a key change. The spec requires that
the end of these messages must align with a record boundary. We can detect
this by checking for decrypted but as yet unread record data sitting in
OpenSSL buffers at the point where we process the messages.
