A lot of hacking:
...
- More work on funneling console output through Console.
- init() now breaks off into a separate task ASAP.
- ..this leaves the "colonel" task as a simple hlt idle loop.
- Mask all IRQs on startup (except IRQ2 for slave passthru)
- Fix underallocation bug in Task::allocateRegion().
- Remember how many times each Task has been scheduled.
The panel and scheduling banner are disabled until I get things
working nicely in the (brave) new Console world.

More paging stuff.
...
The test userspace process now runs at linear address 0x300000 which is
mapped to a dynamically allocated page from the MemoryManager. Cool!

A userspace process can now GPF and the OS goes on!
...
This is really rickety, but it kinda sorta works for my test GPF!

These changes were lying around uncommitted in the old repo.
...
I'm just gonna commit them without too much thinking and then take
it from there.

Import the "gerbert" kernel I worked on earlier this year.
...
It's a lot crappier than I remembered it. It's gonna need a lot of work.
