cleanup src/linux and src/misc trees, etc.
previously, it was pretty much random which one of these trees a given function appeared in. they have now been organized into: src/linux: non-POSIX linux syscalls (possibly shard with other nixen) src/legacy: various obsolete/legacy functions, mostly wrappers src/misc: still mostly uncategorized; some misc POSIX, some nonstd src/crypt: crypt hash functions further cleanup will be done later.
