Janos Follath 5d96a3dcde Clarify the use of ECDSA API
In the ecdsa.c sample application we don't use hashing, we use ecdsa
directly on a buffer containing plain text. Although the text explains
that it should be the message hash it still can be confusing.

Any misunderstandings here are potentially very dangerous, because ECDSA
truncates the message hash if necessary and this can lead to trivial
signature forgeries if the API is misused and the message is passed
directly to the function without hashing.

This commit adds a hash computation step to the ecdsa.c sample
application and clarification to the doxygen documentation of the
ECDSA functions involved.

Manuel Pégourié-Gonnard 161ef968db Cache pre-computed points for ecp_mul()
Up to 1.25 speedup on ECDSA sign for small curves, but mainly useful as a
preparation for fixed-point mult (a few prototypes changed in constness).

Manuel Pégourié-Gonnard f499993cb2 Add ecdsa_from_keypair()
Also fix bug/limitation in mpi_copy: would segfault if src just initialised
and not set to a value yet. (This case occurs when copying a context which
contains only the public part of the key, eg.)
