This patch removes the IPC endpoint numbers that needed to be specified
in the IPC files. Since the string hash is a (hopefully) collision free
number that depends on the name of the endpoint, we now use that
instead. :^)
Additionally, endpoint magic is now treated as a u32, because endpoint
numbers were never negative anyway.
For cases where the endpoint number does have to be hardcoded (a current
case is LookupServer because the endpoint number must be known in LibC),
the syntax has been made more explicit to avoid confusing those
unfamiliar. To hardcode the endpoint magic, the following syntax is now
used:
endpoint EndpointName [magic=1234]

The PIDs were used for sharing shbufs between processes, but now that
we have migrated to file descriptor passing, we no longer need to know
the PID of the other side.
The ImageDecoder service now returns a list of image frames, each with
a duration value.
The code for in-process image decoding is removed from LibWeb, an all
image decode requests are sent out-of-process to ImageDecoder. :^)
This won't scale super well to very long and/or large animations, but
we can work on improving that separately. The main goal here is simply
to stop doing any image decoding inside LibWeb.
Fixes#5165.
