Major changes to timing interfaces
...
- 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.

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.

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".
