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 
They now use interrupts and thus can be blocked on without sitting in a
busy loop. Not sure if they still work perfectly, need to debug. Works
fine with the console "serial" stuff in qemu.

Todo: Investigate further.

7c8d34d1b6 Disable EXT2 writes; add experimental tmpfs 
This is still a work in progress. ext2 writes are quite broken, so they
have been completely disabled, but there's a new tmpfs mounted to /tmp
that you can try to poke at. I'm still fixing up quirks in the VFS that
make it incompatible with a bunch of stuff, but I did manage to write
some files with vim, and swap files appear to be working at least
somewhat. It's all still broken as fuck.

Adds a byte to the process struct, but avoids GCC-specific extensions of

anywhere, but will make ./analyze happier.
