configure: remove non-functional --with-opencl-libdir

The parameter used to control where the gallium pipe-drivers
were installed, but was broken since

    targets/pipe-loader: Convert to automake

Considering that nowadays the pipe-drivers can be used by
more than just the opencl target, even fixing this up will
not be the best idea.

configure: drop --with-egl-driver-dir switch

The location of the egl driver(s) is matter that we should have
never exposed to the user. Currently the dri2 driver is built
into the libEGL loader, with the gallium based one soon to follow.

v2: Fold EGL_DRIVER_INSTALL_DIR within the makefiles. Suggested by Matt.

configure: ask vdpau.pc for the default location of the vdpau drivers

Rather than using hardcoded values honor the value set at libvdpau
build time - i.e. the moduledir variable from vdpau.pc

Update the omx description to match reality while we're here.

configure: use explicit enabled/disabled in config switch description

Rather than having double negatives -> disable-opencl, default=no
simply use enabled/disabled. It makes things a bit easier for the
reader and consistent throughout the file.

since the define cannot always be found in config.h depending

freedreno: we have more than 0 viewports!

4155d1c7 'st/mesa: drop dependence on API profile in st_init_extensions'
broke freedreno because somehow 'PIPE_CAP_MAX_VIEWPORTS' fell through
the cracks.  Resulting that we reported zero viewports.  So the state

i965/fs: Walk instructions in reverse in saturate propagation.

When we find a mov.sat, we search backwards. We might as well search
everything else backwards as well and potentially look at fewer
instructions.

This change enables the next patch.

i965/fs: Ignore mov.sat instructions in interference check in sat prop.

When an instruction's result was consumed by multiple mov.sat
instructions, we would decide that we couldn't move the saturate
modifier because something else was using the result, even though it was
just another mov.sat!
