Fix some undefined behaviour in the Curve448 code

We can't add NULL data into a hash

Remove a spurious TLSProxy byte in TLSv1.3

When the proxy re-encrypted a TLSv1.3 record it was adding a spurious
byte onto the end. This commit removes that.

The "extra" byte was intended to be the inner content type of the record.
However, TLSProxy was actually adding the original encrypted data into the
record (which already has the inner content type in it) and then adding
the spurious additional content type byte on the end (and adjusting the
record length accordingly).

It is interesting to look at why this didn't cause a failure:

The receiving peer first attempts to decrypt the data. Because this is
TLSProxy we always use a GCM based ciphersuite with a 16 byte tag. When
we decrypt this it actually gets diverted to the ossltest engine. All this
does is go through the motions of encrypting/decrypting but just passes
back the original data. Crucially it will never fail because of a bad tag!
The receiving party thinks the spurious additional byte is part of the
tag and the ossltest engine ignores it.

This means the data that gets passed back to the record layer still has
an additional spurious byte on it - but because the 16 byte tag has been
removed, this is actually the first byte of the original tag. Again
because we are using ossltest engine we aren't actually creating "real"
tags - we only ever emit 16, 0 bytes for the tag. So the spurious
additional byte always has the value 0. The TLSv1.3 spec says that records
can have additional 0 bytes on the end of them - this is "padding". So the
record layer interprets this 0 byte as padding and strips it off to end up
with the originally transmitted record data - which it can now process
successfully.

AIX: make sure that the arflags value includes the command letter (r)

In previous OpenSSL versions, this letter was part of the make
variable AR.  However, following the usual convention (read: GNU),
this letter is supposed to be part of ARFLAGS.

If s->ctx is NULL then this is an internal error

Coverity was complaining because we checked if s->ctx is NULL and then
later on in the function deref s->ctx anyway. In reality if s->ctx is
NULL then this is an internal error.

DRBG: make locking api truly private

In PR #5295 it was decided that the locking api should remain private
and used only inside libcrypto. However, the locking functions were added
back to `libcrypto.num` by `mkdef.pl`, because the function prototypes
were still listed in `internal/rand.h`. (This header contains functions
which are internal, but shared between libcrypto and libssl.)

This commit moves the prototypes to `rand_lcl.h` and changes the names
to lowercase, following the convention therein. It also corrects an
outdated documenting comment.
