Also fix the #endif comment in a few places and #include config.h to
avoid assuming it is #included implicitly.

The RGB32 pixel format is RGBA/BGRA depending on target
endianness - make sure to convert it to one specific format for
the framecrc tests.

This fixes the pngparser fate test on big endian.

Additional editing by Diego Biurrun

Since pc.state is populated by shifting in from the end of the
32 bit word, the content within pc.state is already in native endian
and should not be read with the AV_R{L,B} functions.

This was already done correctly for state64 above.

This fixes the fate-corepng test on big endian.

Tables are always allocated now with sufficient space for either progressive
or interlaced content. The alternative would be to detect a change
and reallocate.

This fixes decoding of a sample.

Useful for reading png images from a pipe.

It was deprecated over two years ago.

This is necessary to avoid GCC assuming MS style printf arguments.

Applications that have been linked against an older release of Libav and pick up
updated libraries experience segmentation faults because they pick up the new
libavfilter, which assumes AVFrames have been allocated by libavutil and thus
contain new reference-counting related fields. This will break for AVFrames that
have been allocated by old libavcodec.

All scheduled API changes are deferred to the next bump.

Commit 41578f70 changed the LLS API, which was
called from libavcodec. Thus using an old libavcodec with a new libavutil will
break.

This avoids a memory leak (or having to worry about freeing the
config string) if the colorspace isn't accepted.

Uniform the style and eliminate a warning on newer doxygen version..

Some pthreads symbols might be present in libc (as shown on various *BSD)
but not all of them, leading to false positives.

Check for the most common compiler flags before the plain symbol check
to avoid known pitfalls.

There are alternate implementations of those libraries that use pthreads.

This long-deprecated code should disappear at the next version bump.

This enables a more C99-compliant implementation of printf et al.

The MinGW32 project is deprecating its old version macros.

The flag is not unconditionally added to CFLAGS either and the
programs built on the host do not get habitually fed to a debugger.
