LibDEFLATE: Allow decompression from multiple byte spans

WindowServer: Rewrite damaged region tracking
...
Instead of immediately doing rerender of client data and syncing 60 Hz,
we now only keep track of the damaged regions and also do the rerender
step 60 Hz.

LibC: Use IP instead of si_addr for faulting instruction
...
si_addr only means faulting instruction for SIGILL. For SIGSEGV it is
the faulting memory address.

LibGUI/WindowServer: Rework packet serialization
...
Instead of sending while serializing (what even was that), we serialize
the whole packet into a buffer which can be sent in one go. First of all
this reduces the number of sends by a lot. This also fixes WindowServer
ending up sending partial packets when client is not responsive.
Previously we would just try sending once, if any send failed the send
was aborted while partial packet was already transmitted. This lead to
packet stream being out of sync leading to the client killing itself.
Now we allow 64 KiB outgoing buffer per client. If this buffer ever fills
up, we will not send partial packets.

Kernel/LibC: Rework userspace syscall interface
...
Kernel syscall API no longer zeros all unused argument registers and
libc now uses inlined syscall macro internally. This significantly
cleans up generated code for basic syscall wrapper functions.

LibC: Fix pthread cancellation

Install SIGCANCEL handler for all threads.
Remove unneeded atomic stores and loads. States are only changed within
the thread itself.
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.
