Remove redundant checks, save a few muls
...
ecp_mul() already checks for this, and this check is not going away, so no
need to do it twice (didn't even result in better error reporting)

Avoid unnecessary xxx_copy() calls
...
The call would anyway check for pointer equality and return early, but it
doesn't hurt to save a function call, and also this follows more uniformly the
pattern that those two lines go together:
#if defined(MBEDTLS_ECP_RESTARTBLE)
if( rs_ctx != NULL && ...

Keep PK layer context in the PK layer
...
Previously we kept the ecdsa context created by the PK layer for ECDSA
operations on ECKEY in the ecdsa_restart_ctx structure, which was wrong, and
caused by the fact that we didn't have a proper handling of restart
sub-contexts in the PK layer.

Use ecp_gen_privkey() in ECDSA sign
...
Two different changes:
- the first one will allow us to store k in the restart context while
restarting the following ecp_mul() operation
- the second one is an simplification, unrelated to restartability, made
possible by the fact that ecp_gen_privkey() is now public

Improve sign/key_tries handling
...
(Unrelated to restartable work, just noticed while staring at the code.)
Checking at the end is inefficient as we might give up when we just generated
a valid signature or key.
