Emil Velikov 9365ff4b88 egl: move eglCreateDRMImageMESA's malloc later
Don't bother allocating any memory until we're finished parsing and
sanitising all the attributes.

As a nice side effect we now consistently set eglError when any of
the attrib/values are not correct.

Strangely enough the spec does not mention _anything_ about what error
should be set where, even if the implementation already sets the odd
one.

Tomasz Figa 0ede0f9dff egl: android: Fix potential use of unitialized variable
If dri2_setup_extensions() fails, the "err" variable would not be assigned
causing the error path to access an unitialized variable. Fix it by
assigning an error message.

Ben Crocker 162c42f8ed egl_dri2: swrastGetDrawableInfo: set *x, *y [v2]
In swrastGetDrawableInfo, set *x and *y, not just *w and *h;
this fixes a crash later in drisw_update_tex_buffer when the
(formerly) uninitialized x and y values are used to construct
an address in a call to llvmpipe_transfer_map.

Fixes crash in Piglit test
"spec@egl 1.4@eglcreatepbuffersurface and then glclear"
(<piglit dir>/bin/egl-create-pbuffer-surface -auto)
that occurred intermittently, e.g. when the uninitialized x and y in
drisw_update_tex_buffer just happened to contain absurd non-zero values.

v2: Initialize in case if function succeeds or fails, just like *w/*h.

Chad Versace 5e884353e6 egl/android: Change order of EGLConfig generation (v2)
Many Android apps (such as Google's official NDK GLES2 example app), and
even portions the core framework code (such as SystemServiceManager in
Nougat), incorrectly choose their EGLConfig.  They neglect to match the
EGLConfig's EGL_NATIVE_VISUAL_ID against the window's native format, and
instead choose the first EGLConfig whose channel sizes match those of
the native window format while ignoring the channel *ordering*.

We can detect such buggy clients in logcat when they call
eglCreateSurface, by detecting the mismatch between the EGLConfig's
format and the window's format.

As a workaround, this patch changes the order of EGLConfig generation
such that all EGLConfigs for HAL pixel format i precede those for HAL
pixel format i+1. In my (chadversary) testing on Android Nougat, this
was good enough to pacify the buggy clients.

v2: Rebase to make patch cherry-pickable to stable.

Emil Velikov 2c341f2bda egl: refactor dri2_create_screen() into three separate functions
Split the create_screen into:
 - create screen
 - setup/bind extensions
 - setup screen

This will allow us to reuse the latter two on egl/drm. Said platform
does create its own screen and attempts to reinvent the later two
functions itself.

Since the GBM ones tend to get out of sync quite often, and there is no
distinct reason why it does so we'll drop them with latter commits.

v2: disp -> dpy for the Android platform.
v3: use correct goto label (Rob)
