youtube: adding downloader for youtube.com.
concurrency.combinators: adding parallel-assoc-map.
checksums.fletcher: adding Fletcher's checksum in 16/32/64-bits.
checksums.murmur: implementation of MurmurHash.
checksums.murmur: should be unsigned int32.
combinators: fix docs for dispatch since it isn't in kernel.private.
checksums.superfast: implementation of SuperFastHash.
checksums.murmur: make checksum on byte-arrays much faster.
checksums.superfast: make checksum on byte-arrays much faster.
pcre: handle long values in pcre-config and throw errors.
checksums.superfast: reuse code and make a bit faster.
io.binary: faster le> and signed-be>.
checksums.superfast: reuse more code, slightly faster for non-byte-arrays.
io.binary.fast: write generic be> and le> words.
checksums.murmur: use bits word.
checksums.superfast: use bits word.
msgpack: use byte-array instead of strings, faster.
math.bitwise: speed up >signed.
io.binary: speed up signed>.
math.bitwise: removing bit-clear? since it is just "bit? not".
