Kernel: Allow setting thread names

Browse source 
The main thread of each kernel/user process will take the name of
the process. Extra threads will get a fancy new name
"ProcessName[<tid>]".

Thread backtraces now list the thread name in addtion to tid.

Add the thread name to /proc/all (should it get its own proc
file?).

Add two new syscalls, set_thread_name and get_thread_name.
