  options_table: Add aliases for color properties
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>

The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.

(cherry picked from commit 2124711b)

If no string argument is supplied when av_hwdevice_ctx_create() is
called to create a VAAPI device, we currently only try the default
X11 display (that is, $DISPLAY) to find a device, and will therefore
fail in the absence of an X server to connect to.  Change the logic
to also look for a device via the first DRM render node (that is,
"/dev/dri/renderD128"), which is probably the right thing to use in
most simple configurations which only have one DRM device.

(cherry picked from commit 121f34d5)

(cherry picked from commit 582d4211)

No longer leaks memory when used with a driver with the "render does
not destroy param buffers" quirk (i.e. Intel i965).

(cherry picked from commit 221ffca6)
Fixes ticket #5871.

The driver being used is detected inside av_hwdevice_ctx_init() and
the quirks field then set from a table of known device.  If this
behaviour is unwanted, the user can also set the quirks field
manually.

Also adds the Intel i965 driver quirk (it does not destroy parameter
buffers used in a call to vaRenderPicture()) and detects that driver
to set it.

(cherry picked from commit 4926fa9a)

This prevents a division by zero in read_packet.

Set up the encoder with a hardware context which will match the one
the decoder will use when it starts later.

Fixes building for Windows x86 with MSVC using the link libraries distributed with the CUDA SDK.

check_lib2 is required here because it includes the header to get the full signature of the
function, including the stdcall calling convention and all of its arguments, which enables
the linker to determine the fully qualified object name and resolve it through the import
library, since the CUDA SDK libraries do not include un-qualified aliases.

AVFilterLink.frame_count is supposed to count the number of frames
that were passed on the link, but with min_samples, that number is
not always the same for the source and destination filters.
With the addition of a FIFO on the link, the difference will become
more significant.

Split the variable in two: frame_count_in counts the number of
frames that entered the link, frame_count_out counts the number
of frames that were sent to the destination filter.

The test is not supposed to cover audio.
Also, using -vframes along with an audio stream depends on
the exact order the frames are processed by filters, it is
too much constraint to guarantee.

This should fix build with Solaris CC.
