This variable is set to the same value for all directories.
Adding the -L flags directly to LDFLAGS is simpler and achieves
the same thing.

Declaring tools associated with each library in their respective
makefiles allows these tools to easily depend on the correct
prerequisites and link against the libs they need.

It should be replaced with proper per-codec defaults.

We operated on 31-bits, but with e.g. lanczos scaling, values can
add up to beyond 0x80000000, thus leading to output of zeroes. Drop
one bit of precision fixes this.

When using e.g. lanczos scaling, values can drop below 0, so they
should never be unsigned.

We would use the second half of the U plane buffer, rather than the
V plane buffer, to output the V plane pixels.

They were replaced by (de)muxer private options.

The copy regression test script is unused, bash-specific and did
not even work properly when it was originally committed.

AVStream is no place for it and it's unused outside of ffmpeg anyway.

This tests sizes from 16 to 4096, not only the default 512.

Change the test program to output text instead of binary files so
it can be compared easily in FATE.

This prevents random values from the stack being used as

Setting CMP=null uses stdout from the test as the diff record in
the report without further inspection.  This can be useful when
the exit status of the test itself determines success while the
output is informative.

Add al05_44, al06_44, al17_44.

For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

The targets are now part of FATE and can be run as individual FATE targets.

This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

This works through some non-obvious hacks in utils.c.

Setting SRC_PATH to "." when building in-tree removes the need
for a quoted version of the source path since out-of-tree builds
are not possible if the pathname contains spaces.

sets up redirections.  Using the outputs set there simplifies
