Don't include the generated celt/arm/celt_pitch_xcorr_arm-gnu.S in the
dist tarball, but do include its celt_pitch_xcorr_arm.s source file.

Automake's dependency tracking seems to be confused by our asm
generation double-indirection. It's sufficient to have just
CLEANFILES = $(CELT_AM_SOURCES_ARM_ASM:.s.in=-gnu.S)
to fix the error about 'armopts-gnu.S' not being cleaned, but
celt_pitch_xcorr_arm-gnu.S is also not cleaned without raising
a warning. Therefore we explicitly clean both sets of ARM_ASM.

Code is still float, but at least tonality esitmation seems to work.
Speech/music analysis is still disabled.

Automake 1.13 complains that INCLUDES is obsoleted now.

Drop the test for getopt, it's not used anywhere anymore.

Switch the last uses of AC_TRY_COMPILE to AC_COMPILE_IFELSE now.
The former is marked as obsolete, and this will leave no confusion
about which to cut and paste if new tests are added.

Double quote all the parameters to AC_LANG_SOURCE and AC_LANG_PROGRAM.
This is actually required, even if you can get away with not doing it
sometimes, so again set a good example for future changes to follow,
to hopefully avoid people getting bitten harder than they need to be.

Don't bother checking for alloca if we're never going to use it
(ie. if we have C99 variable-size array support).
The test for this is a bit sketchy anyway ...  we separately test for
HAVE_ALLOCA_H and USE_ALLOCA, but the test for USE_ALLOCA depends upon
having alloca.h present, yet the use of these macros in stack_alloc.h
only tests for HAVE_ALLOCA_H inside of a test for USE_ALLOCA.
I'm not going to change this logic right now, since I don't know what
crazy system it was attempting to cater for, though I suspect it was
one that was not using the autoconf build system ... since with the
current test that combination should not be possible to obtain.

Use LT_LIB_M instead of the song and dance with testing for exp().
This should also work for BeOS which is what the exp test was added for.
It also means we don't unconditionally add -lm to everything via LIBS.

Use LIBM now instead of hardcoding -lm everywhere.

Use AS_HELP_STRING to format all option descriptions.

Don't bother to test for doxygen if using it is --disable'd.

Drop the SYMBOL_VISIBILITY export, it isn't used anywhere (we add the
compiler flag to CFLAGS).

It can be disable at compile time with --disable-rtcd option.

Add RTCD support for ARM architecture.

Needed by commit 972a34ec.

Use autoreconf in autogen.sh instead of the handwritten version,
it's simpler, and also updates things that we weren't handling.

Drop the hand-written INSTALL file.  Its information content was
~zero, and autotools wants to overwrite it with its own version,
so don't fight that, just .gitignore it.

There's currently at least one way that people can legitimately get a
tarball that doesn't include it, via the gitweb snapshots, so create
it rather than considering that an error to be manually fixed.

This one meets or exceeds the following requirements:

 - Version is checked/updated for every build action when in the git repo.
   Does not require the user to re- ./configure to get the correct version.

 - Version is not updated automatically when using exported tarball source.
   Avoids accidentally getting a wrong version from some other git repo in
   a parent directory of the source, and allows setting the correct version
   for distro package exports.

 - Automatic updating can be manually suppressed.
   For developers doing lots of change/rebuild cycles they don't plan to
   release, when they don't want a full rebuild triggered for every commit,
   and again for every change made immediately after a commit.
   The version will still always be updated if they do a `make dist`.

 - Does not require any manual updating of versions in the mainline git
   repo for each release aside from normal tagging.  The version is
   recorded in one file only, that is automatical...

This is a heavily modified version of the demonstration program

the current commit, but fail with the tree from two commits ago.

Fixes a regression in the recursive builds introduced in 5467ce7b
that causes `make check-opus` to fail horribly.

Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>

Instead use cd inside the makefiles.
This fixes 'make check', etc. with some non-gnu makes. (HPUX, for example)

Previously we defined the release version string in configure.ac,
and overrode that with 'git describe --tags' if possible. This
made it difficult for non-autoconf builds to set their version
string correctly.

Instead we create, and check into version control, a file called
version.mk which defines OPUS_VERSION. The configure script reads
that file and uses it as a fallback if the git revision isn't available.

The expectation is that version.mk will be manually updated for
releases, just as the previous configure.ac version was. However,
since this is a simpler format, it is easier for alternate build
systems to use, reducing the number of places which must be updated.

Also removes the OPUS_MINOR_VERSION, etc. defines from config.h.

And explicitly specify what we want included in EXTRA_DIST of doc/Makefile.am,
otherwise make dist picks up whatever random junk you might have laying around
in that dir at the time you run it.

Tweak the top level delegation targets, because this means distclean will be
run in the doc dir by default now without our help.

Both are still built and installed by default though.

Remove automake color-tests and parallel-tests because they break solaris and require much newer autotools.

This reverts commit a69368e1.

The opus_headers.txt, etc. files are makefile
fragments defining variables with a list of
required header files for the build. As such
they should use the .mk filename extension,
just like opus_sources.mk, etc.

On my system this speeds up 'make -j8 check' by about
50%. The drawback is that we don't get to see Greg's
nice output from the test programmes. It's hidden in
a log file, even on failure or 'make V=1'. Probably
this is better for most people; developers can run
the tests manually.

Build tests in the tests/ directory instead of top, cleanup, rename,
and eliminate recursive make for the celt/ unit tests.

Renames test_opus to opus_demo and adds the test_opus_api, test_opus_encode, test_opus_decode test programs.

Doxygen is a tool for generating programming documentation
based on comments in header and source files. This commit
adds the necessary configuration file and associated support
in the autotools build.

Right now it doesn't generate much documentation because our
public header files aren't marked up. Warnings are printed
for undocumented members and arguments.
