Markus Triska d19d8ea770 crypto_data_hkdf/4: do not crash for length > usize::max_value() 
For now, we fail silently in such cases.

Markus Triska a423eb5323 stronger validation of input lists for cryptographic routines 
Example:

    ?- crypto_data_hkdf(Var, 32, Bs, []).
    caught: error(instantiation_error,must_be/2)

Reported by @notoria in #527. Many thanks!

Markus Triska fd732550d8 crypto_data_hkdf/4: Fail if the length is too long. 
Due to the way the counter is constructed in the HKDF specification,
the requested output length can be at most 255 times the size of the
digest algorithm's output.

Reported by @notoria in #527. Many thanks!

Markus Triska 23034dd4f5 raise instantiation errors for variable encoding 
Reported by notoria in #527.

Note that from a declarative perspective, it would indeed be valid to
give answers for both available encodings.

Markus Triska 50776748a7 ADDED: HMAC-based key derivation (HKDF) via crypto_data_hkdf/4 
This is useful to generate keys and initialization vectors
from suitable input keying material, so that future predicates
for symmetric encryption can be used with appropriate parameters.

Markus Triska 4084005ee7 ADDED: Reasoning about elliptic curves in library(crypto). 
This is useful to establish shared secrets, using ECDH key exchange.

Note that CLP(ℤ) goal expansion is currently disabled due to #445,
and this slows down the computations considerably for the time being.

This is used for example for Bitcoin address generation.

The ring crate is used since it will be needed also for future
predicates in library(crypto).
