fe6877034d 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.

50b63ba2f5 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

675439620d 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.

32aa4375cc Declare ecdsa_read_signature_restartable() 
Not making ecdsa_verify_restartable() public, as it isn't called from any
other module.

411079fc34 Rm obsolete comment 
Refers to ecp_mul() while we're now calling ecp_muladd().

Wrap long lines while at it.

ca878dbaa5 Make md_info_t an opaque structure 
- more freedom for us to change it in the future
- enforces hygiene
- performance impact of making accessors no longer inline should really be
  negligible
