Saves a copy in the decoder

to mono state transition in the same manner as the encoder.

Remove a redundant negative length check in celt_decode.

draft makefile. Increase precision of the static modes table.

non-ascii characters from the source.

Includes better error handling in fft/mdct init

Pitch search can now go up to 720 samples

The encoder would crash in the PVQ search if fed NaNs via the float interface. This patch protects against it in two sufficient ways: Making the PVQ search robust against NaNs and by squashing NaNs to zero on input.

Thanks to David Richards for reporting this failure mode.

Stop adjusting the VBR drift during silent frames, this prevents overshoot after silent spans. This also results in undershoot on files with lots of silence, but this is desirable in terms of increasing quality consistency. It will be even better if we later include some open-loop correction of the targets.

We don't allow *encoding* a stereo stream with a mono encoder
because that's just silly.

Adds a CELT_GET_LOOKAHEAD() ctl() call instead. Other uses of
celt_mode_info() should not be needed anymore.

These were used because the entropy coder originally came from
 outside libcelt, and thus did not have a common type system.
It's now undergone enough modification that it's not ever likely to
 be used as-is in another codec without some porting effort, so
 there's no real reason to maintain the typedefs separately.
Hopefully we'll replace these all again somedate with a common set
 of Opus typedefs, but for now this will do.

This fixes an issue caused by commit 6c8acbf1, which moved the
 ec_ilog() prototype from entcode.h to ecintrin.h, where the
 ec_uint32 typedef was not yet available.
Thanks to John Ridges for the report.

We were trying to normalize bands that didn't actually exist (e.g.,
 the last band with 320-sample frames at 32kHz).
