Accumulated changes in several submodules.

Specific reason for this build was to test removal of a couple of
TerASIC-specific files.

Other accumulated changes include:

* A bunch of work on the AES core;

* A bunch of minor performance enhancements in the C code, mostly
  related to RSA signature time (which is still a problem, but this
  set of fixes removed a bunch of dumb stuff which was masking what we
  now think is the root cause of the performance issue);

* A bunch of minor fixes and cleanups in the C code (eg, assertions
  now log something to the console rather than just locking up).
