When Brian in 02c3dad0f3 restricted
the shm permissions it means we hit the fallback paths in some
scenarios we hadn't before.
When you use Xephyr to xdmcp from one user to another the new perms
stop the X server (running as user a) attaching to the SHM segments
from gnome-shell (running as user b).
In this case however only the GLX side of the code had insight into this,
and the dri could was meant of fall back, and it worked for put image
fine but the get image path was broken, since there was no indication
in the broken case of the need to fallback.
This adds a return type to a new interface member that lets the
caller know it has to fallback.
Fixes: 02c3dad0f3 ("Call shmget() with permission 0600 instead of 0777")

This adds a new interface to the swrast interface to fix an shm put image bug.
The current code adds the x,y src offsets into the offset parameters,
however if the x offset is > 0, and the put image copies up to the height
of the image, this can trigger an X server validation check to fail and
the renderering to get BadMatch.
This patch fixes it to pass the x offset coord in as a src x.
We cannot pass the Y coordinate due to the horrible code mangling the

Jump through the layers of abstraction between egl and dri in order to
feed the context priority attribute through to the backend. This
requires us to read the value from the base _egl_context, convert it to
a DRI attribute, parse it again in the generic context creator before
passing it to the driver as a function parameter.
In order to not require us to pass back the actual value of the context
priority after creation, we impose that drivers should report the
available set of priorities during screen setup (and then they may chose
to fail if given an invalid value as that should have been checked at
the user boundary.)

"This extension allows an EGLContext to be created with a priority
hint. It is possible that an implementation will not honour the
hint, especially if there are constraints on the number of high
priority contexts available in the system, or system policy limits
access to high priority contexts to appropriate system privilege
level. A query is provided to find the real priority level assigned
to the context after creation."
The extension adds a new eglCreateContext attribute for choosing a
priority hint. This stub parses the attribute and copies into the base
struct _egl_context, and hooks up the query similarly.
Since the attribute is purely a hint, I have no qualms about the lack of
implementation before reporting back the value the user gave!
v2: Remember to set the default ContextPriority value to medium.
v3: Use the driRendererQuery interface to probe the backend for
supported priority values and use those to mask the EGL interface.
v4: Treat the priority attrib as a hint and gracefully mask any requests
not supported by the driver, the EGLContext will remain at medium
priority.

DRI-drivers could call Xlib functions, for example to allocate a new back
buffer.
When glthread is enabled, the driver runs mostly on a separate thread.
Therefore we need to guarantee the thread safety between libX11 calls
from the applications (not aware of the extra thread) and the ones from
the driver.
See discussion thread:
https://lists.freedesktop.org/archives/mesa-dev/2017-April/152547.html
Fortunately, Xlib allows to lock display to ensure thread safety but
XInitThreads must be called first by the application to initialize the lock
function pointer. This patch will allow to check XInitThreads was called
to allow glthread on GLX or EGL platform.
Note: a tentative was done to port libX11 code to XCB but it didn't solve fully
thread safety.
See discussion thread:
https://lists.freedesktop.org/archives/mesa-dev/2017-April/153137.html
Note: Nvidia forces the driver to call XInitThreads. Quoting their manpage:
"The NVIDIA OpenGL driver will automatically attempt to enable Xlib
thread-safe mode if needed. However, it might not be possible in some
situations, such as when the NVIDIA OpenGL driver library is dynamically
loaded after Xlib has been loaded and initialized. If that is the case,
threaded optimizations will stay disabled unless the application is
modified to call XInitThreads() before initializing Xlib or to link
directly against the NVIDIA OpenGL driver library. Alternatively, using
the LD_PRELOAD environment variable to include the NVIDIA OpenGL driver
library should also achieve the desired result."
