a) trade a little bit of code size for speed
(depending on exact caller, compiler might also optimize a lot)
b) reduce the need for exported, but non-public symbol

Since xtrans is now in-tree and already have been trimmed down
for only things needed by the Xserver, the split between xstrans.c
and transport.c isn't needed anymore.

add some macros for making request handlers and byte swapping easier:
* X_REQUEST_HEAD_STRUCT(type) and X_REQUEST_HEAD_AT_LEAST(type)
declare header struct pointers and check size
* X_REQUEST_FIELD_CARD16(field)
swaps a CARD16 (word) header field (if neccessary)
* X_REQUEST_FIELD_CARD32(field)
swaps a CARD32 (dword) header field (if neccessary)
* X_REQUEST_REST_CARD16()
swaps remaining CARD16 array payload (if necessary)
* X_REQUEST_REST_CARD32()
swaps remaining CARD32 array payload (if necessary)
* X_REQUEST_REST_COUNT_CARD16(count)
check swaps `count` CARD16 payload fields and checks size
* X_REQUEST_REST_COUNT_CARD32(count)
check swaps `count` CARD32 payload fields and checks size
How to use them:
1. put X_REQUEST_HEAD_STRUCT() or X_REQUEST_HEAD_AT_LEAST() ontop of each Proc*()
2. add X_REQUEST_FIELD_*() et al below, for all fields to be swapped and
drop the corresponding SProc*()'s
3. let the dispatchers call Proc*() instead of SProc*()
Notes:
* the length field is already swapped before request handlers called

Current code walks along all screens and initializes screen resources,
then gc's, stipples, root windows for each of them, hence after
the first screen registering new private keys is no more possible.
This crashes modesetting driver if it is not initialized before others.
This patch makes screen resources for all screen initialize first, hence
all necessary private keys (including of the type PRIVATE_WINDOW) are
initialized before root windows are created.

The space needed to store these extra values is at worst a few dozen bytes.
In exchange for these, larger cursors glyphs can use a more optimal cursor size.

Make the code a bit easier to read by using initialization of the reply
structs, at the point of declaration. Most of them aren't written to later,
just passed into WriteReplyToClient(). Also dropping some useless zero
assignments (struct initializers automatically zero-out unmentioned fields).

After the dmabuf fd exported by another screen is imported to a pixmap,
the pixmap holds a reference for the buffer, thus the FD itself finished
its job and needs to be closed to prevent a stale reference to the
buffer.

Added a workflow to check the commit messages of a PR to make sure each is

Xvmc isn't using SHM for over 20 years now. There's still a code path for it
that could be enabled explicitly by manually setting HAS_XVMCSHM, but no
indication whatsoever that this ever has been done.
Considering that Xvmc in general already is obsolete for very long time now,
we can safely assume this code path is really dead and can be removed.
