Switch constant-time functions to using |crypto_word_t|.

Using |size_t| was correct, except for NaCl, which is a 64-bit build
with 32-bit pointers. In that configuration, |size_t| is smaller than
the native word size.

This change adds |crypto_word_t|, an unsigned type with native size and
switches constant-time functions to using it.
