Move all BigInt stuff into bigint/. Currently all asm modules are disabled;

configure.pl doesn't understand how to handle this yet (replace logic only
understands stuff in src, not how one module can replace another modules
src, or anything about prioritizing).

Move some hex and base64 stuff out of charset.cpp and into their
codec directories.
