Library soname versioning is something we normally change
only right before each release. However, with 1.0.2 being
released from the 1.0.x branch with 3.0.3, it makes sense
to make the same update here. That way when we do a new
release from master we can just increment again and have
the version properly reflect ranges relative to the stable
branch.

This applies in addition to the earlier grant made by
Skype, which was purchased by Microsoft.

PLC and FEC now return exactly the number of samples specified for the
buffer rather than (usually) returning the size of the last packet.
Doc and tests are updated accordingly.

This avoids linker errors with VS2010 of the form
    failure during conversion to COFF: invalid file or corrupt
    [c:\users\giles\opus\source\opus_demo.vcxproj]

The problem does not occur if the project files are updated
to build under VS2012.

This is a heavily modified version of the demonstration program
Jüri Aedla posted to the mailing list. Verified to pass with
the current commit, but fail with the tree from two commits ago.

This was reported by Juri Aedla and is limited to reading memory up
to about 60 kB beyond the compressed buffer. This can only be triggered
by a compressed packet more than about 16 MB long, so it's not a problem
for RTP. In theory, it *could* crash an Ogg decoder if the memory just after
the incoming packet is out-of-range.

We don't ever use the WORDS_BIGENDIAN cpp symbol in our code.

Was causing problems with the PLC

Previous code was so broken that it's`not worth listing the changes.
Aside from quality, one obvious improvement is a 3.75k reduction in stack size

The README doesn't say anything about this particular define.
Refer people to config.h and the other build files for examples.

OPUS_EXPORT was conditionalized on OPUS_BUILD, so that symbols
are export based on public header declarations when building
opus as a library, but not when those headers are included in
other programmes. This doesn't address the case when the opus
source and its caller are both included in the same monolithic
build.

In that case we want to define OPUS_BUILD, to indicate that we
are compiling the codec source, but not export the symbols. To
support this, only define OPUS_EXPORT if it is not already defined.
This allows build scripts to -DOPUS_EXPORT and override the
platform-specific attribute decortation in opus_defines.h.

Based on a patch by Sergey Ulanov.

We always define OPUS_BUILD, so this code has no effect.
Likewise there is no reason for it to be conditional.
According to Jean-Marc it's left over from when we had
an alternate CELT_BUILD define.

This also adds some extra casts to shut up compiler warnings
 reported on MSVC 6 where there is implicit truncation for the
 arguments of bitexact_cos().
Lacking access to CLZ/BSR will make the code a fair bit slower but
 that is better than failing to compile.

Made RFC6716 a normative reference, removed non-sensical constraints,
updated contact info, ...

Thanks to Randell Jesup for the feedback.

This allows the sender parameters sprop-maxcapturerate and
 sprop-stereo to be specified on a per-SSRC basis, instead of just
 per m-line.

Instead of using the average energy over the frame, we use a half-way
point between the average energy and the max energy.

Passing 'enable' as an argument to AM_MAINTAINER_MODE flips the
default to enabled, rather than disabled until automake 1.11.
This is a safer default for a developer-oriented library.

./configure --disable-maintainer-mode is still available for
packagers who what to preserve the upstream build distribution.

On earlier automake versions, the argument appears to have no
effect, so there is no behaviour change for developers using
older autotools.
