This is a port of virtual dub's histogram equalization filter by Donald
A. Graft. Based on the work by Jérémy Tran <tran.jeremy.av@gmail.com>,
done for SOCIS 2012.
This is a port of the kerndeint filter (libmpcodecs/vf_kerndeint) by
Donal A. Graft (original avisynth plugin author), and is based on the
work by Jérémy Tran <tran.jeremy.av@gmail.com> done for SOCIS 2012.
Also fixes linking in various configs with only individual parts enabled
because the RTP muxer chaining code depends on the general RTP code,
which is now accounted for.
Ported from MPlayer. Original author is A'rpi, with various
contributions from Michael Niedermayer. The original documentation was
mostly written by Diego Biurrun. See the MPlayer history for full
credits.
The filter is under GPL like the original filter, even if it differs
quite a lot. There is not much point in making it LGPL since pp is under
GPL.
Beginning with version 1.5.1 openjpeg defaults to install its headers to
/usr/include/openjpeg-${major}.${minor} instead of /usr/include without
providing a compatibility symlink making the old test fail.

Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

This fixes the automatic use of $foo_extralibs when feature foo
is enabled indirectly through a _select or _suggest.

This is consistent with usual ARM nomenclature as well as with the
VFPV3 and NEON symbols which both lack the ARM prefix.

This allows compiling optimised functions for features not enabled
in the core build and selecting these at runtime if the system has
the necessary support.

This tests instruction set support in both inline and external asm.
If both fail, the base config option is disabled.

The check_insn function tests an instruction in both inline asm and
standalone assembly, and sets _external/_inline config properties
accordingly.

These are properties of the targeted core and do not depend on
specific assembly support in the toolchain which if missing will
render the controlling options here disabled.

Probe for the toolchain default architecture version if no --cpu flag
is present or an unknown cpu is specified. Works with gcc, clang and
armcc.
This allows configuring based on the arch version even if it is not
explicitly specified to configure. It also causes an explicit -march
flag to be added to CFLAGS and ASFLAGS, which in turn lets us do
proper instruction set tests with the assembler.

This will allow arch-specific ways of determining the target
variant when none is specified on the command line.

The check_inline_asm function should check the actual C compiler,
not the one used for assembly files. Usually these are the same,
but they might be different, typically when using a compiler other
than gcc.
The check_as should, as its name suggests, test the type of input
the AS command is used with, i.e. a standalond assembly (.S) file.
Finally, check for gnu assembler using the modified check_as as
this reflects actual usage.

Check building a simple piece of code and disable thumb if it fails
This fixes a compile failure
If someone has a better idea, just replace this by it!

The def files are used for generating import libraries for
other toolchains (in particular, for generating import libraries
for MSVC for DLLs built with mingw).
The def files produced by mingw/gcc contains ordinals for each
exported function. When MSVC tools generate import libraries
from such a def file, MSVC links to the DLL by the ordinals
instead of linking by name.
Since the def files aren't maintained by hand, the ordinal
numbers are assigned (more or less) randomly and any caller
linking to the libs by ordinals will break as soon as the libraries
export more/fewer functions.
Therefore, strip out the ordinals from the generated def files,
to make users link to the libraries by name.
Callers linking to the DLLs using the gcc provided import library
link by name as they should.
