Hashsig cleanup.

- Move hashsig.h contents into hal.h.

- Uppercase lmots and lms algorithm types, because we have a convention
  that enum values are uppercase.

- Change all I to hal_uuid_t, because that how we're using them, and it
  seems silly to have two different 16-byte array types.

- Change all "memcpy(&this, &that, sizeof(this))" to "this = that",
  because it's more succinct, more type-safe, and harder to get wrong.

- Slightly tighten up lmots_generate, lmots_sign, and
  lmots_public_key_candidate.

- Remove verbatim draft text, now that I'm pretty sure I implemented it
  correctly.
