To match creation on a newly-derived device.  (This was missed earlier
because the mode is only used in some cases.)

Intended to replace existing opencl mode of the unsharp filter.
Supports many more pixel formats and works without immediate upload
and download of frame data.  The options are compatible with the
existing filter.

Input and output formats must be the same, the overlay format must be
the same as the input except possibly with an additional alpha component.

Using cl_arm_import_memory.  Unfortunately, despite this not being a
standard extension, the function clImportMemoryARM() is not accessible
via clGetExtensionFunctionAddressForPlatform().  This means that it has
to be linked directly to the ARM OpenCL binary, so making a portable
binary is not possible as it is with all other mapping extensions.

Using cl_khr_d3d11_sharing and cl_intel_d3d11_nv12_media_sharing.

Using cl_khr_dx9_media_sharing.

Uses the cl_intel_va_api_media_sharing extension, which supports only
NV12 surfaces and only mapping from QSV to OpenCL.

Supports all surface formats in common between the two.

Add two FAQs about running FFmpeg in the background.
The first explains the use of the -nostdin option in
a straightforward way. Text revised based on review.

The second FAQ starts from a confusing error message,
and leads to the solution, use of the -nostdin option.
The purpose of the second FAQ is to attract web searches
from people having the problem, and offer them a solution.

Add an anchor to the Main Options section of the ffmpeg
documentation, so that the FAQs can link directly there.

In the event of ff_mov_read_stsd_entries() failure, sc->stsd_count
is not updated, even if the function allocates extradata memory.
Instead update the sc->stsd_count as entries are parsed so that
mov_read_close() can do the right thing.
