Poly1305: Use |size_t|; assert |poly1305_state| is large enough.

Clarify that there are no truncation issues on targets where the range
of |unsigned| is smaller than the range of |size_t|.

Ensure that |poly1305_state| is (still) large enough. This is a good
idea independently of this change, but is especially important because
switching the fields to |size_t| might have enlarged the structures.
