Bananymous a4ba1da65a 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.

Bananymous 2f9b8b6fc9 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.

Bananymous 2a4a688c2d 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.

Bananymous e7d644b874 AudioServer: Fix rounding the number of samples when resampling 
If client tried to play a single sample at lower frequency as the

this
