b160dc0f31 Xnest: add helper for retrieving GC XID on upstream connection 
Upcoming patches will need to retieve GC's XIDs on the upstream connection.
Moving this out into separate .c file, in order to not creating more
dependencies on Xlib headers, which we wanna get rid of.

For now, looking at the Xlib GC structure, attached to our DDX GCs.
When all users of the Xlib GC have gone (ie. moved all consumers to xcb),
we'll create the GC via xcb directly, thus replacing the Xlib GC struct
by XID - the interface of this helper will remain the same.

Fetching the setup data from xcb instead of Xlib, storing in our own struct,
holding all information needed for one particular upstream connection.
For now, there's only one, but future multi-upstream implementation will
change this to an array (and storing pointers to particular upstream in
various places).

cab3856903 xfree86: os-support: fix FTBS when no recent enough libdrm found 
On Linux, the only supported platform bus backend (*1) is via DRM/DRI.
Trying to build it w/o (recent enough) libdrm fails as it tries to
compile the drm-based implementation, w/o having drm.h available. (*2)

In order to fix this, we need to compile noop-implementation instead.

*1) platform specific code for detecting video devices

628e94b164 os: let vpnprintf() accept %X 
Several pieces of the code, as well as drivers are using %X, which
we don't support, so leading to error messages like this:

In the longer run, we'll have to decide whether we actually want to
implement the upper-case directive or change all callers to lower-case.

But for now it's better to just accept %X and interpret it as lower-case,
in order to fix those error messages. Whether it's printed as upper or
lower case is more or less an aesthetic matter.

53876f1ef1 randr: fix RRGetCrtcTransform reply length, part 2 
Mixed up reply vs request. Obviously, the size substracted from reply
struct's one has to be the one of the generic reply, not generic requst :o

Background: the meaning of the length field isn't entirely intuitive.

a) the size is in 4-byte units, instead of bytes (therefore passing through
   bytes_to_int32() call)
b) it's not the total packet size, but only the *extra* payload size, ergo:
   how much is the packet longer than a xGenericReply = 8 units = 32 bytes.
   (min. packet size is 32 bytes -> length = 0)

In order to prevent those kind of coding errors ever happening again, it might
be a good idea putting that into a generic macro.
