Kernel: Store memory region size as uint64_t
...
On 32 bit target, we were storing 32 bit physical region sizes which
would truncate regions > 4 GiB

LibC: Fix pthread cancellation

Define pthread_testcancel as a macro so it gets inlined inside
cancellation points

LibGUI: Optimize invalidate and set alpha channel
...
If the window does not have an alpha channel, we now set every pixel's
alpha to 0xFF. This is needed by the WindowServer when it does alpha
blending, there used to be some weird stuff happening on overlapping
windows.
Also when we are invalidating a region with width of the whole window,
we can do a single memcpy instead of a memcpy for each row separately.

WindowServer: Optimize rendering
...
We now use SSE2 to do alpha blending on 4 pixels at a time where
possible and use memcpy instead of manual loops for non blended regions.

Kernel: Be more clever with physical memory
...
Initially allocate all physical memory except kernel memory and boot
modules. Before we just skipped all memory before kernel boot modules.
Also release memory used by boot modules after the kernel is up and
running. Once the boot modules are loaded, there is no need to keep them
in memory.

Kernel: Clean up signal handling
...
We now appreciate sa_mask and SA_NODEFER and change the signal mask for
the duration of signal handler. This is done by making a sigprocmask
syscall at the end of the signal handler. Back-to-back signals will
still grow stack as original registers are popped AFTER the block mask
is updated. I guess this is why linux has sigreturn(?).

Kernel: If userspace sets fs or gs, dont overwrite it
...
Current cpu index is stored at either segment. If userspace sets that
segment, kernel will not overwrite it on every reschedule. This is fine
as long as user program does not use anything that relies on it :)
