3a0a8848fb Make syscall invocations look pleasant.
Old: Syscall::invoke(Syscall::SC_foo, (dword)arg1, (dword)arg2)
New: syscall(SC_foo, arg1, arg2)

fdbd9f1e27 Start working on memory-mapped files.
First of all, change sys$mmap to take a struct SC_mmap_params since our
sycsall calling convention can't handle more than 3 arguments.

This exposed a bug in Syscall::invoke() needing to use clobber lists.
It was a bit confusing to debug. :^)

1d5afbdffc Add sys$set_mmap_name and use it from LibC's malloc.
It's nice to be able to identify mmap's in /proc/PID/vm.

260b14e505 Implement errno in LibC.
This also meant I had to implement BSS (SHT_NOBITS) sections in ELFLoader.
I also added an strerror() so we can print out what the errors are.
