Speex has build in silence detection. If speex_encode_int returns 0,
than there is silence and sample do not need to be transmitted.
This work only if vbr=1 and dtx=1 optionas are enabled.
So if we get 0, we add GAP flag to the sample.
If we did not know how many frames to expect, then we get an unexpected
end of stream when trying to decode more frames that are there, if there
are leftover bits to pad to the next byte
Looking at the remaining bits in the bitstream after decoding a
single frame can't be used as loop condition. The remaining
bits might not give a complete frame and the speex decoder will
then output nothing but access uninitialized memory, which leads
to valgrind warnings.
Fixes bug #644669.
Using the symbols for the different Speex modes results
in crashes when using MSVC. Use the library functions to
get the modes instead.
Fixes bug #630378.
Link to properties. Correct titles for examples. Document a few trivial cases. Keep lists in section file and docs/plugins/Makefile.am alphabetically ordered. Fix warnings that gtk-doc points out.

Use integer encoding and decoding functions instead of converting
the integer input to float in the element. The libspeex integer
functions are doing this for us already or, if libspeex was compiled
in integer mode, they're doing everything using integer arithmetics.
Also saves some copying around.

* ext/speex/gstspeexenc.c: (gst_speex_enc_encode):
Correct the timestamp and granulepos calculation by one Speex
frame.
Original commit message from CVS:
* ext/speex/gstspeexdec.c: (speex_dec_chain_parse_data):
Correctly take the granulepos from upstream if possible and
correctly handle the granulepos in various calculations: the
granulepos is the sample number of the _last_ sample in a frame, not
the first.

Try to preserve input timestamps when we can.
Do beginnings of error concealment.
Original commit message from CVS:

Fix bounds checking of mode in Speex header, which may

Use different variables for nested for loops so that the outer loop
functions properly and speex files with multiple frames per buffer work
properly.

broken tags with libgsttag-based code. Plus miscellaneous
code cleanups (use static pad templates etc.) and a bunch
of leak fixes.
