LibC: Add mmap_with_name() that names the allocation immediately.
...
This allows us to skip the separate call to set_mmap_name() in code that
we control, e.g malloc() and GraphicsBitmap.

Kernel+LibC: Add stubs for POSIX shared memory API.
...
Specifically shm_open() and shm_unlink(). This patch just adds stubs.

LibC: mmap() should not interpret high addresses as errors, oops!

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

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. :^)

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.

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.
