So we don't accidentally interrupt a read or something.

4d8335ad75 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.

e3ffd36083 Fix critical exec issue with not freeing old dir 
We weren't freeing old page directories on exec, so regardless of the
actual size needed for the new process, we ended up with a huge address
space usage. Now, all of the memory from the other process is going to
be copied on the fork, and we can't do anything about that (beyond
writing a separate syscall that forks+replaces without the copy, or
implementing CoW, the latter being preferred) but that's at least a
well-know "problem".

e5aa49beda (hack) make /dev listings work 
This is a bit of a hack. /dev is presented as a new pseudo file type
until I finish the VFS overhaul. This fake file presents a directory
with entries for all of the VFS nodes that are children of it. The
future VFS will do this on its own, thus making this superfluous.
