Huge incompatible changes.

- Obsolete skalibs/environ.h and skalibs/getpeereid.h removed.
- rc4 and md5 removed.
- All *_t types renamed to avoid treading on POSIX namespace.
- subgetopt() renamed to lgetopt().
- signal functions reworked; skasigaction removed; sig_stack removed
- Various functions removed: skaoffsetof(), selfpipe_untrap()
- New posixplz function: munmap_void.
