No need to keep CXX around.
test_endian: fix uint64 check
test_regex: skip test that glibc fails
makefile: asm and size tagets
find_modules: work with subdirs
Move crypto files

There will be more, so give them subdirectory.
crypto: reorder arguments in _final()

The old one was final(dst, ctx) which is some sort of historical
accident.  Lets get rid of it.  Then all operations on hash context
take context as first argument.
crypto/digest: common framework for digests

The digests will be easier to use (and test) if they share
common wrapper API.
crypto: SHA2 digests

Separate module for both SHA-256 and SHA-512.
crypto: Add Keccak (SHA3) algorithm

It is based on Keccak reference implementation, but cleaned
up for SHA3-only usage.
find_module: avoid big regex
Move simple hashes under separate subdirectory.

There may be more of them.
usual/hashing/siphash: SipHash-2-4

New secure hash.
usual/wchar: wide-char utilities.
usual/fnmatch: fnmatch compat
