If the user supplies a device or frames context then it is an error
not to use it; this is consistent with other hardware components.

Also factorise out the D3D11 initialisation and improve error
messages.

When using clang-cl it expects parameters passed in MSVC-style, so appropriate toolchain should be selected.
As soon as both clang and clang-cl report themselfs as "clang" with -v option the only chance to detect
clang-cl is passing -? option to both which is valid for clang-cl.exe and not for clang.exe.

If a frame starts very close to a packet boundary, the start code may
already have been added to the parsing buffer, indicated by a small
negative value of "i", while the header is still being tracked in the
"state" variable.

Reduce the remaining size accordingly, otherwise trying to find the next
frame could skip over the frame header and lump two frames together as
one.

If the parser returns full frames, then the output pointer retured by
av_parser_parse2() is guaranteed to point to data contained in the
input packet's buffer.

Create a new reference to said buffer in that case, to avoid
unnecessary data copy when queueing the packet later in the function.

In some cases, mainly working with multiprogram mpeg-ts containers as
input, it would be handy to select sub stream of a specific program by
their metadata.
This patch makes it possible to narrow the stream selection among
streams of the specified program by stream metadata.

Examples:
p:601:m:language:hun  will select all sub streams of program with id 601
where sub streams have metadata key named 'language' with value 'hun'.
p:602:m:guide  will select all sub streams of program with id 602 where
sub streams have metadata key named 'guide'.

Fixes trac ticket #7099.

For some odd reason, the Nvidia version macros puts the minor version in
the msb, so comparing against it is impossible.

When using hls_list_size with hls_flags delete_segments, currently
hls_list_size * 2 +- segments remain on disk. With this new option,
the amount of disk space used can be controlled by the user.
