14c45338e9 EVP_MD_size() updates
For SHAKE algorithms we now return 0 from EVP_MD_size().
So all the places that check for < 0 needed to change to <= 0
(Otherwise the behaviour will be to digest nothing in most cases).

6f22bcd631 Add appropriate NULL checks in EVP_CIPHER api
The EVP_CIPHER api currently assumes that calls made into several APIs
have already initalized the cipher in a given context via a call to
EVP_CipherInit[_ex[2]].  If that hasnt been done, instead of an error,
the result is typically a SIGSEGV.

Correct that by adding missing NULL checks in the apropriate apis prior
to using ctx->cipher

4bf610bdce Remove enc_write_state
This field was used to track whether a cipher ctx was valid for writing
or not, and also whether we should write out plaintext alerts. With the new
record layer design we no longer need to track whether a cipher ctx is valid
since the whole record layer will be aborted if it is not. Also we have a
different mechanism for tracking whether we should write out plaintext
alerts. Therefore this field is removed from the SSL object.

e077455e9e Stop raising ERR_R_MALLOC_FAILURE in most places
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called.  Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

With the removal of SSLv2, the s3 structure is always allocated, so
there is little point in having it be an allocated pointer. Collapse
the ssl3_state_st structure into ssl_st and fixup any references.

This should be faster than going through an indirection and due to
fewer allocations, but I'm not seeing any significant performance
improvement; it seems to be within the margin of error in timing.
