Lyude Paul 186a21c4ba glamor: Unbreak glamor_fd_from_pixmap()
When support for allocating GBM BOs with modifiers was added,
glamor_fd_from_pixmap() was changed so that it would return an error if
it got a bo with modifiers set from glamor_fds_from_pixmap(). The
problem is that on systems that support BOs with modifiers,
glamor_fds_from_pixmap() will always return BOs with modifiers.

This means that glamor_fd_from_pixmap() was broken entirely, which broke
a number of other things including glamor_shareable_fd_from_pixmap(),
which meant that modesetting using multiple GPUs with the modesetting
DDX was also broken. Easy reproducer:

- Find a laptop with DRI prime that has outputs connected to the
  dedicated GPU and integrated GPU
- Try to enable one display on each using the modesetting DDX
- Fail

Since there isn't a way to ask for no modifiers from
glamor_fds_from_pixmap, we create a shared _glamor_fds_from_pixmap()
function used by both glamor_fds_from_pixmap() and
glamor_fd_from_pixmap() that calls down to the appropriate
glamor_egl_fd*_from_pixmap() function.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
