a8890a5f2d Use PIT mode 2 instead of 3 
Works around what is believed to be a bug in VirtualBox where the PIT
*and* RTC were slowing down while playing quake to roughly half their
expected rates. I have no idea why this fixes the problem, but it does,
and with no expected ill effects elsewhere. With the future 64-bit
kernel, ToaruOS will no longer being using the PIT, so it doesn't really
matter anyway.

39da315a48 Build a dynamic userspace. 
- Builds (terrible, broken) shared versions of (most) third-party
  dependencies for the userspace.
- Fixes several incorrect dependency mappings in auto-dep.
- Makes auto-dep understand shared libraries (and that some things,
  like OSMesa, don't work with them).
- init must be built static because reasons
- some libraries were cleaned up to fix dependency calculation
- version bumped to 0.99.0 (saten) for eventual 1.0.0 release.
- CDs no longer drop teapot, select-wallpaper (space is available
  for them - we could even make the images smaller)

9a72bfc4cd Add half-assed support for IRQ chaining. 
We only support 4 total chain entries at the moment, but that can be
"easily expanded"... We don't really have a lite dynamic vector, just
the big fat dynamic lists, so improving on this needs some extra effort.

This commit also drags in a bunch of random network work by necessity.

- The kernel version has been bumped to 0.9.0
- The timer resolution in the kernel has been increased to millseconds.
- The preemptive scheduling interval has been descreased to one
  millisecond.
- Relative sleep continues to use 10 millsecond intervals for legacy
  reasons.
- `gettimeofday` now uses the internal tick counter to calculate the
  current time. Drift is calculated from the CMOS every 5 seconds and
  applies only to `gettimeofday` and other places that use it.
- The resolution of timing information provided by debug functions has
  been increased to three digits (milliseconds).
- The resolution of timing information provided by the procfs uptime
  virtual file has been increased to three digits (milliseconds).
- Functions have been added to the debug shell to read the TSC. The TSC
  is not used in timing functions at this time.

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".
