Fix PIT Interrupt Not Context Switching [irq]
...
PIT interrupt should context switch or else all of redox crashes.
This will fix programs like the Snake game crashing all of Redox.
A global AtomicUSize counter was added, and a line to switch contexts
on every 10 PIT interrupts in irq.rs.

Avoid multiplication in memcpy family functions
...
Instead of multiplying everything by 8[/4], now addition is used. That
way code is prettier.

A faster implementation of the memcpy family
...
The default implementation of the memcpy, memmove, memset and memcmp
functions in the kernel file `extern.rs` uses a naive implementation
by copying, assigning or comparing bytes ony by one. This can be slow.
This commit proposes a reimplementation of those functions by copying,
assigning or comparing in group of 8 bytes by using the u64 type and
its respective pointers instead of u8. Alternative version for 32-bit
architectures are also supplied for future compatibility with x86.
Both version first copy whatever they can with wide word types. The
tail, i.e. the final few bytes that do not fit in a dword or qword
are then copied byte by byte.
Here is a comparison of copying 64kiB (65536 bytes) on stack:
x86_64-unknown-linux-gnu: (64-bit)
| naive (ns) | fast (ns) | speedup (x)
-------|------------|-----------|------------
memcpy | 204430 | 32994 | ~6.20
memmove| 202540 | 33186 | ~6.10
memset | 163391 | 23884 | ~6.84
memcmp | 205663 | 34385 | ~5.98
i686-unknown-linux-gnu: (32-bit)
| naive (ns) | fast (ns) | speedup (x)
-------|------------|-----------|------------
memcpy | 206297 | 66858 | ~3.09
memmove| 204576 | 70326 | ~2.91
memset | 165599 | 50227 | ~3.30
memcmp | 204262 | 70572 | ~2.89
Copying on the heap behaves simmilarly.
All tests performed on Intel i5 6600K (4x4.2GHz),
ArchLinux Kernel 4.8.12-3 x86_64.
