Neither opening a screen nor querying its modifiers confers the right to
attach the buffer for any particular pixmap. GetAttr seems more correct.

We were mixing stdint and CARD* types, causing compiler warnings on

to be using long term, anyway.

Checking for dri3_screen_info_rec.version >= 2 is insufficient,
as some shipping drivers, e.g., intel-ddx, nouveau-ddx, set the
version to DRI3_SCREEN_INFO_VERSION, ie. to whatever version the
installed servers headers define. On server 1.20 that would
be version 2, but the drivers still don't support the v1.2
hooks. Make sure all hooks are defined before reporting v1.2.
Also make clamping of reported version to minimum of client
or server robust against possible future clients with possible
majorVersion >= 2.0.

The old info->fd_from_pixmap() driver hook, which is
preferentially used in dri3_fd_from_pixmap(), can return
error codes other than -1, e.g., -EINVAL (-22) on nouveau-ddx.
Not handling the error causes a broken/corrupted X-Connection
resulting from a failed request.
This fixes failure of sddm-greeter to start up under nouveau-ddx
with DRI3 enabled and DRI3 protocol version properly clamped
to 1.0 by the server (see followup patch).

Both xf86-video-intel and xf86-video-nouveau cause OpenGL clients to
fail when used with DRI3 on server 1.20 with Mesa 18.1.
Reason is that the servers DRI3 version is now unconditionally reported
as DRI3 1.2 to 1.2 capable clients. This causes clients using Mesa 18.1
to use the new DRI 3.2 requests DRI3GetSupportedModifiers,
DRI3PixmapFromBuffers, etc. Drivers other than modesetting-ddx do not
support the needed hooks like info->pixmap_from_fds or
info->get_formats, info->get_modifiers. Unfortunately we can't simply
report the servers DRI3 version as 1.0 in this case, as the reported
version can not be specific to a X-Screen, and different screens may
have drivers with different capabilities.
Luckily the server has fallbacks to ->pixmap_from_fd, ->fd_from_pixmap,
and simply reporting an empty set of supported modifiers for the
DRI3GetSupportedModifiers request if the ddx doesn't support DRI 3.2.
Clients like Mesa 18.1's dri3 loader respond to the empty set of
reported modifiers by falling back to a dri driver selected buffer
format (image->createImageWithModifiers responds to a NULL modifier_list
by acting like ->createImage()). This works, but Mesa 18.1 will still
try to use the DRI3PixmapFromBuffers request to create the corresponding
pixmap, just passing in a modifier that corresponds to whatever tiling
the dri driver selected by default. To prevent this request - and
thereby the client - from failing with a BadImplementation error, remove
the check for modifier == DRM_MOD_FORMAT_INVALID in the pixmap_from_fd
fallback path of dri3_pixmap_from_fds() and trust that if we hit the
fallback path then the client will have passed a buffer with some driver
specific default tiling that can be handled by pixmap_from_fd.
Another approach would be for Mesa's dri3 loader to keep track how a
buffer was created (with explicit modifiers or not), and then call
DRI3PixmapFromBuffers or DRI3PixmapFromBuffer, but then any future DRI3
client implementation would need to be fixed, so the server side is
probably the better place for this.
Tested on Intel Ivybridge and NVidia Pascal.

Currently if the function fails, we'll fall into two false assumptions:
- the the count is zero
- that the storage pointer is safe for free()
I've just fixed the former (in glamor + xwayland) and have no
plans on adding yet another workaround for the latter.
Simply zero both variables. Regardless if the implementation is missing
the callback or it foobars with output variables (normally a bad idea).
Bonus points - this fixes a bug where we feed garbage to free() further
down ;-)

When importing client buffers into Pixmaps, we can use the fds_to_pixmap
hook for both single-FD and multi-FD client requests without any harm.
For the other direction of exporting Pixmap buffers to client FDs,
create a new helper which calls the old pixmap_to_fd hook if available.
This allows the implementation to ensure that the Pixmap storage is
accessible to clients not aware of multiple planes or modifiers, e.g. by
reallocating and copying.
This makes it possible to run a compositing manager on an old GLX/EGL
stack on top of an X server which allocates internal buffer storage
using exotic modifiers from modifier-aware GBM/EGL/KMS.

This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far. The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet. The unit tests are also not done.
The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools. meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.
v2: Fix indentation nits, move version declaration to project(), use
existing meson_options for version-config.h's vendor name/web.

There's no reason to advertise this extension unless one of the
hardware drivers actually supports it. Not listing it means it's
slightly easier for users to tell what's going on.
On the other hand, not listing it means we may have applications that
only check for the extension and not for appropriate per-screen
support. I don't think that's a real risk as DRI3 is only useful for
systems with deep knowledge of the hardware.
