Implement proper wait/waitpid. This is a pretty big commit, so let's run through it in parts: - All of the userspace changes are to switch away from syscall_wait Mostly, this is to waitpid; some things were tweaked to do things "properly" instead of waiting for particular processes. Init has been fixed to do a proper spin wait. - syscall_wait is gone - as are its uses. newlib bindings have been using just waitpid for a while now. - waitpid now performs like a Unix waitpid - process reaping is no longer a "do this on next change thing": it happens when a process is waited on, like it should (That means we can have real zombies: terminated processes that have not yet been waited on) - Reparenting of children to init has been implemented, so you can fork-daemonize! Overall, this is pretty big... So I hope it doesn't break everything. 2014-04-27 12:37:33 +04:00			`#include <sys/wait.h>`
