66820f350d Tweaks the CELT fractional resampling delay to get perfect alignment 
Also using the same int->float conversion functions for SILK as for CELT
and changed encoder implementation default to constrained VBR just to
be safe when VBR gets more aggressive.

54518c879a Last part of the LPC work stabilization work discussed at the last meeting 
Also adds the encoder part of commit ee8adbe701 as well as a few
minor cleanups.

a26b2be2f9 Improvements to the tests, add a TEST_OPUS_NOFUZZ to disable testing corrupted input. 
No changes to the codec itself.

286f11efea Making the PLC robust to overflows caused by extreme bit-streams 
This is not strictly necessary because the only streams that cause these
already sound horrible, but it helps the testing process.

ee8adbe701 Fixes a few minor issues (no bit-stream change) 
- Safer gain clamping for PLC
- Makes opus_decoder_get_nb_samples() report an error on invalid ToC
- Giving a free license to the text ofthe draft (not just the code)

a51ebd6831 Accuracy improvements to help float implementations 
Also clamps the gain to avoid forcing a float decoder to emulate the
state rescaling.

5609cec9a5 Fixes two minor issues found in random testing at ridiculously low rate. 
- When it cannot produce the rate it's being asked, the encoder now
  returns a "PLC packet"
- Makes it possible to use the CELT PLC for more than 20 ms

bf75c8ec4d SILK fixes following last codec WG meeting 
decoder:
- fixed incorrect scaling of filter states for the smallest quantization
  step sizes
- NLSF2A now limits the prediction gain of LPC filters

encoder:
- increased damping of LTP coefficients in LTP analysis
- increased white noise fraction in noise shaping LPC analysis
- introduced maximum total prediction gain.  Used by Burg's method to
  exit early if prediction gain is exceeded.  This improves packet
  loss robustness and numerical robustness in Burg's method
- Prefiltered signal is now in int32 Q10 domain, from int16 Q0
- Increased max number of iterations in CBR gain control loop from 5 to 6
- Removed useless code from LTP scaling control
- Optimization: smarter LPC loop unrolling
- Switched default win32 compile mode to be floating-point

resampler:
- made resampler have constant delay of 0.75 ms; removed delay
  compensation from silk code.
- removed obsolete table entries (~850 Bytes)
- increased downsampling filter order from 16 to 18/24/36 (depending on
  frequency ratio)
- reoptimized filter coefficients

6619a73637 Move nbits_total initialize before renormalization. 
The range decoder used to initialize nbits_total after the
 renormalization loop, even though the renormalization loop
 modifies it.
This was presumably safe, because nothing actually used the value
 before it was initialized, but I'm tired of it triggering the
 integer overflow checking.

92c896e880 Fixes the code for optional self-delimited packing to make it fit the draft 
This has no impact on opus_demo, test vectors, or "normal" codec operation
