Xv currently calls glamor_xv_free_port_data at the end of every putImage.
This leads to shader recompilation for every frame, which is a huge performance loss.
This commit changes behaviour of glamor_xv_free_port_data, and its now is called only
if width, height or format is changed for xv port.
Shader management also done in a port now, because if shaders will be
stored in core glamor and try to be reused, this can lead to a bug if we
try to play 2 videos with different formats simultaneously.

If texture can be uploaded to GL using glTexImage2D normally, but
cannot be read back using glReadPixels, we still can accelerate it,
but we cannot create pixmap with FBO using this texture type. So,
add a flag to avoid such creations.
This allow us to accelerate 8-bit glyph masks on GL ES 2.0, because those
masks are used only as textures, and in next stages are rendered on RGBA
surfaces normally, so, we do not need to call glReadPixels on them.
This is needed for correctly working fonts on GL ES 2.0, due to inability
to use GL_RED and texture swizzle. We should use GL_ALPHA there, and
with this format we cannot have a complete framebuffer. But completed
framebuffer, according to testing, is not required for fonts anyway.
Also it fixes all 8-bit formats for GLES2.

Some hardware (preferably mobile) working on GLES3 way faster than
on desktop GL and supports more features. This commit will allow using
GLES3 if glamor is running over GL ES, and version 3 is supported.
Changes are the following:
1. Add compatibility layer for 120/GLES2 shaders with defines in and out
2. Switch attribute and varying to in and out in almost all shaders
(aside gradient)
3. Add newGL-only frag_color variable, which defines as gl_FragColor on
old pipelines
4. Switch all shaders to use frag_color.
5. Previous commit is reverted, because now we have more than one GL ES
version, previous commit used to set version 100 for all ES shaders, which
is not true for ES 3

`glamor_make_current` is always called before any calls to GL.
Apply some dirty-tracking to whenever we call `glamor_make_current` so
that we can avoid a decent amount of redundant GL work on each
Dispatch cycle.
Gamescope previously was waking up an empty Xwayland server with an
XQueryPointer and I noticed a significant amount of churn doing
redundant GL work.
This has been addressed on the Gamescope side as well, but avoiding any
useless GL context switches and flushes when glamor is doing nothing
is still beneficial for CPU and power usage on portable devices.

Since 8702c938b3 the pixmap formats are
handled in a single place. In the process of conversion the difference
between pixmap formats that can be uploaded and those that can be
rendered on GL side has been lost. This affects only 1-bit pixmaps: as
they aren't supported on GL, but can be converted to a R8 or A8 format
for rendering (see glamor_get_tex_format_type_from_pictformat()).
To work around this we add a separate flag that specifies whether the
format actually supports rendering in GL, convert all checks to use this
flag and then add 1-bit pixmap formats that don't support rendering in
GL.

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.
