The protocol selection code is now consolidated in a few consecutive
short functions in a single file and is table driven. Protocol-specific
constraints that influence negotiation are moved into the flags
field of the method structure. The same protocol version constraints
are now applied in all code paths. It is now much easier to add
new protocol versions without reworking the protocol selection
logic.
In the presence of "holes" in the list of enabled client protocols
we no longer select client protocols below the hole based on a
subset of the constraints and then fail shortly after when it is
found that these don't meet the remaining constraints (suiteb, FIPS,
security level, ...). Ideally, with the new min/max controls users
will be less likely to create "holes" in the first place.

Looking over names, it seems like we usually use names ending with
_new and _free as object constructors and destructors. Also, since
EVP_MD_CTX_init is now used to reset a EVP_MD_CTX, it might as well be
named accordingly.
Reviewed-by: Rich Salz <rsalz@openssl.org>
The idea is that with EVP_MD_CTX_create() and EVP_MD_CTX_destroy(),
EVP_MD_CTX_cleanup and EVP_MD_CTX_init is not used the same as before.
Instead, we need a single function that can be used to reinitialise an
existing EVP_MD_CTX that's been created with EVP_MD_CTX_create()
previously. Combining EVP_MD_CTX_cleanup and EVP_MD_CTX_init into
that one function is the answer.

This change required some special treatment, as HMAC is intertwined
with EVP_MD. For now, all local HMAC_CTX variables MUST be
initialised with HMAC_CTX_EMPTY, or whatever happens to be on the

change as soon as HMAC_CTX becomes opaque.
Also, since HMAC_CTX_init() can fail now, its return type changes from
void to int, and it will return 0 on failure, 1 on success.
