Remove the "ghash-neon" crypto_shash algorithm. Move the corresponding assembly code into lib/crypto/, and wire it up to the GHASH library. This makes the GHASH library be optimized on arm (though only with NEON, not PMULL; for now the goal is just parity with crypto_shash). It greatly reduces the amount of arm-specific glue code that is needed, and it fixes the issue where this optimization was disabled by default. To integrate the assembly code correctly with the library, make the following tweaks: - Change the type of 'blocks' from int to size_t. - Change the types of 'dg' and 'h' to polyval_elem. Note that this simply reflects the format that the code was already using, at least on little endian CPUs. For big endian CPUs, add byte-swaps. - Remove the 'head' argument, which is no longer needed.
