When a pixmap is created with a backing FBO, the FBO should be cleared
to avoid rendering uninitialized memory. This could happen when the
pixmap is rendered without being filled in its entirety.
One example is when a top-level window without a background is
resized. The pixmap would be reallocated to prepare for more pixels,
but uninitialized memory would be rendered in the resize offset until
the client sends a frame that fills these additional pixels.
Another example is when a new top-level window is created without a
background. Uninitialized memory would be rendered after the pixmap is
allocated and before the client sends its first frame.
This issue is only apparent in OpenGL implementations that don't zero
the VRAM of allocated buffers by default, such as RadeonSI.

We had various helper functions trying to come up with the
internalformat/format/type/render formats for pixmaps, and it's much
nicer to just detect what those should be once at startup. This gives
us a chance to do the right thing for GLES.
It also, notably, fixes our format/type for depth 15 and 16 setup for
desktop GL, so that we actually allocate 16bpp (GL_RGB/565) on most
drivers instead of 32bpp (GL_RGB/UBYTE).
GLES still has regressions over desktop (2 regressions in llvmpipe
XTS, many in rendercheck), but I think this is a good baseline.

Keep track of whether or not we fed modifiers into GBM when we allocated
a BO. We'll use this later inside Glamor, to reallocate buffer storage
if we allocate buffer storage using modifiers, and a non-modifier-aware
client requests an export of that pixmap.
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.

It is a modest performance improvement (2.7% on Intel), with the
significant downside that it keeps extra pixmap contents laying around
for 1000 BlockHandlers without the ability for the system to purge
them when under memory pressure, and tiled renderers don't know that
we could avoid reading their current contents when beginning to render
again. We could use the FB invalidate functions, but they aren't
always available, aren't hooked up well in Mesa, and would eat into
the performance gains of having the cache.

A1 and A8 pixmaps are usually stored in the Red channel to conform
with more recent GL versions. When using these pixmaps as mask values,
that works great. When using these pixmaps as source values, then the
value we want depends on what the destination looks like.
For RGBA or RGB destinations, then we want to use the Red channel
for A values and leave RGB all set to zero.
For A destinations, then we want to leave the R values in the Red
channel so that they end up in the Red channel of the output.
This patch adds a helper function, glamor_bind_texture, which performs
the glBindTexture call along with setting the swizzle parameter
correctly for the Red channel. The swizzle parameter for the Alpha
channel doesn't depend on the destination as it's safe to leave it
always swizzled from the Red channel.

For pictures without alpha, and for most other formats for GLES2, we
would make a temporary FBO, make another temporary texture, upload our
GLAMOR_MEMORY pixmap to the texture, then run the "finish access" shader
across it to swizzle its values around into the temporary FBO (which we
would use for a single Render operation and then throw away).
We can simplify everything by using GL_ARB_texture_swizzle (or its
GLES3 counterpart). It's just not worth the complexity to try to
improve the performance of this already low-performance path (SHM
pixmaps + Render) on GLES2.

This avoids a lot of screwing around to attach our privates later. It
means that non-glamor pixmaps now gain 120 bytes of glamor privates on
64-bit (which has quite a bit of fixable bloat), and glamor pixmaps
take one less pointer of storage (not counting malloc overhead).
Note that privates start out zero-filled, which matches the callocs we
were doing when making our own privates, and in the case of an fb
pixmap that has a priv where it didn't before, the type ends up being
GLAMOR_MEMORY as we would want.
