9a71c7759a Implement loading of linked ELF executables. 
This took me a couple hours. :^)

The ELF loading code now allocates a single region for the entire
file and creates virtual memory mappings for the sections as needed.

Very nice!

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.

56ed448424 Move ELFLoader debug output behind flags. 
The logging spam was out of control.

97e0d75bcb ELFLoader works inside the kernel! 
We load /_hello.o which just prints out a simple message.
It executes inside the kernel itself, so no fancy userspace process
or anything, but this is still so cool!
