Add TIOCGWINSZ ioctl so userland can determine terminal geometry.
...
(Don't) use this to implement short-form output in ls.
I'm too tired to make a nice column formatting algorithm.
I just wanted something concise when I type "ls".

Finally hook up the mkdir code to a syscall.
...
Added a /bin/mkdir that makes directories. How very neat :^)
There are various limitations because of missing functionality.

Some improvements to signals.
...
- Add sigprocmask() and sigpending().
- Forked children inherit signal dispositions and masks.
- Exec clears signal dispositions and masks.

Add some basic signal support.
...
It only works for sending a signal to a process that's in userspace code.
We implement reception by synthesizing a PUSHA+PUSHF in the receiving process
(operating on values in the TSS.)
The TSS CS:EIP is then rerouted to the signal handler and a tiny return
trampoline is constructed in a dedicated region in the receiving process.
Also hacked up /bin/kill to be able to send arbitrary signals (kill -N PID)

More work towards getting bash to build.
...
Implemented some syscalls: dup(), dup2(), getdtablesize().
FileHandle is now a retainable, since that's needed for dup()'ed fd's.
I didn't really test any of this beyond a basic smoke check.

We're quite far from bash building, but we'll get there eventually!
