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.

ac17214207 Added ability to check if an IRQ is already occupied.
A proper solution would probably be to introduce shared IRQs at some
point in time.

0f344f2900 Rewrite fork/clone.
This is still a bit ugly, needs cleanup.
Fixes that weird GCC issue.

339b82e10c [massive commit] Userspace terminal.
Completely removes:
* The kernel terminal (both VGA and graphical)
* The kernel ANSI parser (obviously)
* kgets() function
* Dozens of other functions that were made useless

Adds:
* Userspace terminal that should work (relatively) well
* Keyboard device driver (implemented with a "pipe" object)
* Stabalized interrupt interface
* `clear` uses the c library
* All panic screens and kprintf() output goes to the serial line ONLY
* The kernel boots directly into /bin/terminal (no arguments, unless you
  want to add them (such as -f))

0b6cc503af [isrs] Increment the IRQ semaphore before...
... handling any interrupt service routines.

This was causing crashes while running /userspace/ apps without any
syscalls being triggered, presumably due to switching at awkward times.

021585e9ef [misc] Massive improvements to process handling
- Free process resources when a process exits (reaped in next process
  cycle; should probably reap after a wait() or something)
- Free process struct after wait()
- Fix page allocation
- Fix fork() return value for child process (attempted to write to an
  invalid point in kernel-stack memory)

We shouldn't be triple faulting randomly anymore!

Continue investigating the fork() return value, as there was a bugged
return at some point during executon of a test run of thrash-process.
