While no decoder currently exports spherical information, this type
represents a frame property that has to be passed through from container
to frames.

Supporting the system was a nice joke for the 9 release, but it has
run its course. Nowadays Plan 9 receives no testing and has no
practical usefulness.
mythtv have problem with non-seekable dont write duration and filesize
and there have problem with some other server and player with 0 value
duation and filesize.
So add a flv flags to fix the ticket and make a choose for users.

Expands the parser to also accept the separator '-' in addition to
'+', and take the negative sign into consideration.
The optional sign for the first factor in the expression is already
covered by parsing for an integer.

If makeopts_fate is set, these makeopts are used for running the
tests instead of the normal makeopts. If it isn't set, the normal
makeopts variable is used as before.
This is useful if remote testing on a lesser machine where a large
number of parallel jobs might be undesireable, while wanting to speed
up the build with many parallel processes.

This patch moves the av_frame_make_writable() call from fill_yuv_image
to get_video_frame so that its argument can be the actual frame that
will be sent to the encoder.
This fixes data corruption issues in codecs that keep references on
one or several previous frames.

The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.
(cherry picked from commit 2124711b95)
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 4926fa9a4a)
Also contains the following changes to the library:
- add ff_ prefix to functions
- remove cplusplus defines.
- add FF_ prefix to contants and some structs
- remove true peak calculation feature, since it uses its own resampler, and
af_loudnorm does not need it.
- remove version info and some fprintf(stderr) functions
- convert to use av_malloc
- always use histogram mode for LRA calculation, otherwise LRA data is slowly
consuming memory making af_loudnorm unfit for 24/7 operation. It also uses a
BSD style linked list implementation which is probably not available on all
platforms. So let's just remove the classic mode which not uses histogram.
- add ff_thread_once for calculating static histogram tables
- convert some functions to void which cannot fail
- remove intrinsics and some unused headers
- add support for planar audio
- remove channel / sample rate changer function, in ffmpeg usually we simply
alloc a new context
- convert some static variables to defines
- declare static histogram variables as aligned
- convert some initalizations to mallocz
- add window size parameter to init function and remove window size setter
function
- convert return codes to AVERROR
- fix indentation

Add keyframe index metadata
Used to facilitate seeking; particularly for HTTP pseudo streaming.
1. read live streaming or file by sequence
2. if use add_keyframe_index option, add a mark flag at the position,
use to insert new context at the last step.
3. add the keyframes *offset* and *timestamp* into a list
4. if use add_keyframe_index option, shift the metadata data from
mark flag offset
5. insert the keyframes *offset* and *timestamp* from the list by
sequence
6. free the list
7. end.
Add FATE test case;
