As part of this, move release creation to a script to be called from
.travis.yml.  That makes it much easier to test outside of travis.

Add new flag TLS1_FLAGS_RECEIVED_EXTMS which is set when the peer sends
the extended master secret extension.

Server now sends extms if and only if the client sent extms.

Check consistency of extms extension when resuming sessions following (where
practical) RFC7627.

It seems like some tar versions don't like the name:id form for
--owner and --group.  The closest known anonymous user being 0 (root),
that seems to be the most appropriate user/group to assign ownership
to.  It matters very little when unpacking either way.

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.

This follows the same idea as the combination of EVP_MD_CTX_cleanup
and EVP_MD_CTX_init into one function.

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 moves the definition to crypto/include/internal/evp_int.h and

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
stack will be mistaken for actual pointers to EVP_MD_CTX.  This will
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.
