Functions interrupted by url_interrupt_cb should not be restarted.
Therefore using AVERROR(EINTR) was wrong, as it did not allow to distinguish
when the underlying system call was interrupted and actually needed to be
restarted.
This fixes roundup issues 2657 and 2659 (ffplay not exiting for streamed
content).

This is different from AVERROR(EINTR) because calls that fail with EINTR
should usually be restarted.

This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done
before determining the rematrixing strategy. Also, the rematrixing strategy
calculation must use 64-bit math to prevent overflow due to the higher
precision coefficients.
In the event of overflow, the JV_PADDING state will avio_skip over
any overflow bytes (using JVFrame.total_size).

In fbdev_read_packet(): nanosleep returns -1 in case of errors,
the EINTR check has to be done on errno.

This makes existing pkg-config uses as well as the libsdl checks
use the new pkg-config helper functions, which should be more
robust against broken systems.

This adds helper functions for checking packages with pkg-config
and managing the associated flags.
Note that pkg-config use is still discouraged due to widespread
poor practices resulting in broken flags in many situations. A
few badly designed packages require flags only obtainable using
pkg-config, and these functions are intended for those cases.

This makes it possible to pass a space-separated list of functions
to check_func_headers and check_lib2. If any function is missing,
none are enabled as available, so this should only be used for
all-or-nothing sets, i.e. groups in which none will be used if any
one is missing.

In the main loop, stream_number is incremented after checking the stream type,
so the search usually will not find the wanted stream.
This patch eliminates the useless stream_number variable and introduces a new
one, called real_stream_index to store the real stream index of the current
stream, no matter if we are looping through all the streams or only the streams
of a program.

The Broadcom CrystalHD decoder chips provide hardware video
decoding for a number of video formats. It does so using a
memory:memory interface where a compressed bitstream is fed
in and decompressed pictures are copied out. As such, it works
independent of any graphics hardware in the system.
Features supported in this initial version:
* Support for Linux (using current drivers/library from git.wilsonet.com)
* Support for 70015 hardware
* Formats: MPEG2, MPEG4 Part 2, H.264, VC1 and DivX 3.11 (untested)
* Progressive content
* Non-H.264 Interlaced content
* H.264 MBAFF content
Features missing in this initial version:
* Support for OSX (might work - untested)
* Support for Windows
* Support for 70012 hardware
