LibC: The standard C library needs to be able to build as pure C.
...
Looks like we can't use those comfy C++ attributes in this code then.

Use modern C++ attributes instead of __attribute__ voodoo.
...
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.

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)

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

Add getpwent() family of functions to LibC.

Also add a little /etc/passwd database. There's just me in there.
