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.

7344a50fe0 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.

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".

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.

Kevin Lange
cc4391d783 Initial work on modules 
There's a lot here, so let's through it:
- Lots of work to include a symbol table in the kernel. We can't rely on
  our bootloader to give us our own ELF information, so we do this
  separately. This probably should be changed to output a C source
  rather than assembly, but that's a TODO.
- Makefile can now generate modules. It works basically the same way any
  other kernel object works, expect with a slightly different linking
  scheme.
- Commands have been added to the debug shell to load modules, but they
  don't work yet - still need to get through relocation and linking.
- Commands have been added to the debug shell to print the symbol list,
  as well as print symbol values (but note that printing symbol values
  is kinda dangerous if you don't know what they are, so don't just go
  printing things willy-nilly).

10f4cc6811 Tasklets; fix dead sleep; kernel serial console 
- Tasklets are essentially kernel threads. Still working on passing
  arguments to them, but they essentially just run functions and have
  special names like [[kttydebug]]. Eventually, I want disk scheduling
  and various (non-interrupt-driven) drivers running on these, but I'm
  still not sure how stable they are.
- Fix the scheduler so it supports not having anything to run. This took
  some tracking of what's running, and then inserting some liberal
  sleeps. Doesn't appear to break anything. Makes the system work when
  you try to sleep with only one process "running", so that's good.
- Start working on reimplementing the old kernel shell, but this time as
  a tasklet running in the background over serial. Probably going to try
  to add all the same features as before (tab completion, history, rich
  editing), but it may take some time to get it all in there. This
  console is mostly focused on helping with debugging EXT2 and other
  future stuff.

8dfd4ff20a Make serial devices more useful
