135d1c9848 More make dist fixes 
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.

d5cb06305b Fix 'make distclean'. 
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.

cbe93e23be Adds OPUS_SET_PREDICTION_DISABLED() ctl to force "independent" frames 
Works by turning off pitch and energy prediction in CELT, while
setting first_frame_after_reset in SILK to disable pitch and LSF interpolation
and reduce LPC gain.

d7aadd808f Fixes a bug where the encoder was trying to use redundancy in CELT mode 
The problem was that forcing CELT-mode for low bitrate CBR was done too late,
after the encoder had decided to use SILK. This was causing redundancy
to be allocated because the encoder didn't realize it was going to keep
using CELT.

9c23f5cdca Makes stereo savings still less aggressive 
Caps the savings at 1 bit per (coded) sample. This doesn't really increase
the bitrate and fixes some issues, e.g. with IgorC's "twilight" sample.
