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.

-/*
- * This version has been further modified by Rich Felker, primary author
- * and maintainer of musl libc, to remove table generation code and
- * replaced all runtime-generated constant tables with static-initialized
- * tables in the binary, in the interest of minimizing non-shareable
- * memory usage and stack size requirements.
- */
-/*
- * This version is derived from the original implementation of FreeSec
- * (release 1.1) by David Burren. I've made it reentrant, reduced its memory
- * usage from about 70 KB to about 7 KB (with only minimal performance impact
- * and keeping code size about the same), made the handling of invalid salts
- * mostly UFC-crypt compatible, added a quick runtime self-test (which also
- * serves to zeroize the stack from sensitive data), and added optional tests.
