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.
This patch adds support for client side resizing, so clients can request
the server to resize their windows. WindowServer will respond with
resize event when and if the resizing is complete.
Windows can now change whether they have title bar, rounded corners,
alpha channel and whether they are movable. Also windows can also change
their own position
userspace programs are now in userspace/programs
userspace tests are now in userspace/tests
This makes listing userspace projects much cleaner. Libraries were
already separated to their own directory, so other programs should also.
