The previous commit removed version negotiation on an HRR. However we should
still sanity check the contents of the version field.

Previously if a client received an HRR then we would do version negotiation
immediately - because we know we are going to get TLSv1.3. However this
causes a problem when we emit the 2nd ClientHello because we start changing
a whole load of stuff to ommit things that aren't relevant for < TLSv1.3.
The spec requires that the 2nd ClientHello is the same except for changes
required from the HRR. Therefore the simplest thing to do is to defer the
version negotiation until we receive the ServerHello.
Fixes#4292

Add functions to return DH parameters using NID and to return the

RFC7919 parameters but could be expanded in future.

If BN_FLG_STATIC_DATA is set don't cleanse a->d as it will reside
in read only memory. If BN_FLG_MALLOCED is not set don't modify the
BIGNUM at all.
This change applies to BN_clear_free() and BN_free(). Now the BIGNUM
structure is opaque applications cannot create a BIGNUM structure
without BN_FLG_MALLOCED being set so they are unaffected.
Update internal DH routines so they only copy pointers for read only
parameters.

Add an ENGINE to EVP_PKEY structure which can be used for cryptographic

RSA_setup_blinding() calls BN_BLINDING_create_param() which later calls
BN_mod_exp() as follows:
BN_mod_exp(ret->A, ret->A, ret->e, ret->mod, ctx)
ret->mod will have BN_FLG_CONSTTIME set, but ret->e does not. In
BN_mod_exp() we only test the third param for the existence of this flag.
We should test all the inputs.
Thanks to Samuel Weiser (samuel.weiser@iaik.tugraz.at) for reporting this
issue.
This typically only happens once at key load, so this is unlikely to be
exploitable in any real scenario.

Now that we are moving to support named FFDH groups, these fields are not
ec-specific, so we need them to always be available.
This fixes the no-ec --strict-warnings build, since gcc
5.4.0-6ubuntu1~16.04.4 appears to always try to compile the static inline
functions from ssl_locl.h, even when they are not used in the current
compilation unit.
