Kernel: Fix deadlock caused by multithreading
...
This allows multiple threads to concurrently call the most common
blocking syscalls:
- read
- write
- accept
- connect
- sendto
- recv
- pselect
This prevents a dead lock when for example process is waiting on a pipe,
but unable to write to it since process is locked.
This is the beginning of starting to remove processes own lock from
syscall and locking only necessary parts.

Kernel: Implement MemoryRegion pinning

This allows process to pin a MemoryRegion into users memory space for
syscall duration without allowing user to munmap the region.

Kernel: Fix E1000{,E} driver for older qemu versions

This patch adds clearing of *Interrupt Cause Registers*, which allows
older qemu versions to send new interrupts. Apparently this is not
needed on newer releases.

LibC: Implement basic pthread mutexes

This implementation is just calling sched_yield if it could not get
mutex. This is not optimal as it does not allow the CPU to idle, but it
works for now :)
Also I did not test this code at all, but it feels correct :D
