Fixes subtle breakage which could sometimes trigger after a server reset
with multiple screens using glamor:
Screen A enters glamor_close_screen last and calls various cleanup
functions, which at some point call glamor_make_current to make sure
screen A's GL context is current. This sets lastGLContext to screen A's
&glamor_priv->ctx. Finally, glamor_close_screen calls
glamor_release_screen_priv, which calls free(glamor_priv).
Later, screen B enters glamor_init, which allocates a new glamor_priv.
With bad luck, this can return the same pointer which was previously
used for screen A's glamor_priv. So when screen B's glamor_init calls
glamor_make_current, lastGLContext == &glamor_priv->ctx, so MakeCurrent
isn't called for screen B's GL context, and the following OpenGL API
calls triggered by glamor_init mess up screen A's GL context.
The observed end result of this was a crash in glamor_get_vbo_space
because glamor_priv->vbo didn't match the GL context, though there might
be other possible outcomes.
Assigning the actual GL context pointer to lastGLContext prevents this
by preventing the false negative test in glamor_make_current.

As a result, the FBO is NULL and glamor segfaults when trying to access

This happens with glamor-xv which uses 8-bit pixmaps, meaning that on

Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.
Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.
These changes ensure that the following modules update the screen in
the correct order:
animated cursors (uses RegisterBlockAndWakeupHandlers dynamically)
composite (dynamic wrapping)
misprite (dynamic wrapping)
shadow (static wrapping)

It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix

the GL rendering is done before we copy it to the front buffer.

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.

We can simplify everything by using GL_ARB_texture_swizzle (or its
