bb42deee36 egl/android: HAVE_DRM_GRALLOC path fixes (v2)
Fixes the following building errors:

external/mesa/src/egl/drivers/dri2/platform_android.c:1001:9: error: use of undeclared identifier 'dri2_img'
                                           dri2_img);
                                           ^
external/mesa/src/egl/drivers/dri2/platform_android.c:1059:17: error: incompatible pointer types assigning to '__DRIimage *' (aka 'struct __DRIimageRec *') from '_EGLImage *' (aka 'struct _egl_image *') [-Werror,-Wincompatible-pointer-types]
      dri_image = droid_create_image_from_name(disp, buf);
                ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2 errors generated.

(v2) Changelog:
- Pass NULL instead of dri_image as argument of createImageFromName()
- Delete the unused dri_image variable

42420730d1 egl/x11: Free memory allocated for reply structures on error
This patch fixes memory leaks when reply is allocated and is not freed
on error execution path.

Found by enabling address sanitizer on simple EGL app.

```c

int main()
{
    EGLDisplay display = eglGetDisplay(EGL_DEFAULT_DISPLAY);
    EGLint major;
    EGLint minor;

    if (!eglInitialize(display, &major, &minor))
    {
        return 1;
    }
    eglTerminate(display);
    return 0;
}
```

Compiled with: `gcc testme.c -o testme -fsanitize=address -lasan -lEGL`

Execution environment:
- Windows 10, VMWare Player 15.5.2 build-15785246 without 3D accelaration
- Guest OS: OpenSUSE Leap 15.2
- Mesa 19.3.4

Program output:

```sh
ASAN_OPTIONS=fast_unwind_on_malloc=0 ./testme

f88b9eb9c5 egl/android: Add support for CrOS buffer info perform op
This uses a new gralloc perform op that returns the buffer info we
need.  No need to guess at formats, hard code offsets and recalculate
strides.  This also gives us the format modifier as well as aux planes
for compressed RGBA buffers.

b67695d597 egl/haiku: drop overwritten preset of EGL version
`init_haiku()` is called by `eglInitialize()`, which then calls
`_eglComputeVersion()` (without even anything in between). The latter
sets the EGL version based on the extensions supported, and since Haiku
doesn't support any it will end up overwriting the same `1.4` value.

d0e32e5f81 egl/dri2: only take a dri2_dpy reference when binding a new context/surfaces
This effectively reverts part of 2907faee, which changed dri2_make_current() to
always take a dri2_dpy reference regardless of whether or not a new context or
surface(s) were being bound. This led to a reference count imbalance as there
was no corresponding code added to drop a reference on the dri2_dpy. As a
consequence, any application that called eglInitialize() on a default/native
display after having called eglTerminate() would always get back the old
dri2_dpy, inheriting its previous state.

As the reference count is there to prevent the dri2_dpy from being destroyed
between eglTerminate() and eglInitialize() calls when a context is still bound,
a reference should only be taken when a successful call to
dri2_dpy->core->bindContext() has been made. Fix the issue by restoring the old
reference counting behaviour.

2907faee7a egl/dri2: try to bind old context if bindContext failed
This change mostly touches error handling code paths, where a
bug was found when the DRI driver failed to bind a new DRI
context. Specifically, the reason for it to fail was the window
system unable (for whatever reason) to provide the DRI drawable
with a buffer. In this instance, Mesa un-does the EGL bindings,
but doesn't restore the old DRI context, hence remaining in a
funny state. It's worth mentioning that despite trying, there
is no guarantee that the old DRI context can be restored,
depending on the runtime.

Before this change, if bindContext() failed then
dri2_make_current() would rebind the old EGL context and
surfaces and return EGL_BAD_MATCH. However, it wouldn't rebind
the DRI context and surfaces, thus leaving it in an
inconsistent and unrecoverable state.

After this change, dri2_make_current() tries to bind the old
DRI context and surfaces when bindContext() failed. If unable
to do so, it leaves EGL and the DRI driver in a consistent
state, it reports an error and returns EGL_BAD_MATCH.
