This is a new library for audio sample format, channel layout, and sample rate
conversion.

This allows simplifying the Makefiles; it is no longer necessary to register
arch subdirectory Makefiles, just putting them in place is enough.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

FFT code only appears in libavcodec, so there is no need to reset the variable
when the build templates are instantiated for other libraries.

Fixes make install.

It will be further developed with a few incompatible changes.

ffmpeg.c will stay as is for some time, so any scripts using it won't be
broken.

This ensures the linker picks the just built libraries even
if LDFLAGS for some reason contains -L flags pointing at
other directories containing libav libraries.

The libs are added to the all target elsewhere, no need to do it
again here.

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.

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

GNU make 3.81 apparently does not support order-only prerequisites
with pattern rules, and thus fails to create the tools directory
if it is missing.  Naming the objects explicitly in the rule makes
it work properly.

These commands have the same form, and using a common macro allows
it to be used elsewhere without further duplication.

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.

Use intermediate targets instead of variables for conditional
parts of "all" and "install" targets.
