LibC: Add some things needed to build GNU bc.
...
This patch adds vprintf(), sig_atomic_t, random() and strdup().
bc doesn't build yet, but it will.

A bunch of compat work (mostly stubs but some real implementations, too.)
...
Another pass at getting bash-1.14.7 to build. Not that many symbols remain.

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 random compat hacking towards getting bash to build.
...
I'm now at the build stage where it complains about a bajillion missing
symbols. This is a good place to be!

Lots of minor compat stuff while seeing if bash would build.
...
We're quite far from bash building, but we'll get there eventually!

A bunch of LibC boilerplate stuff added while trying to get figlet to build.

Implement basic sys$kill() and add a /bin/kill
...
All it can do right now is send SIGKILL which just murders the target task.
