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.

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
* H.264 PAFF content

Although not documented, clang does support the --sysroot flag, and it
does the right thing. Use this flag intead of -isysroot which only
applies to header file searches, not the linker.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
