2016-06-07get_bits: Move BITSTREAM_READER_LE definition before all relevant #includesDiego Biurrun
This avoids the danger that get_bits.h might get indirectly #included before BITSTREAM_READER_LE is defined. Also sort headers into canonical order where appropriate.
2016-01-04vorbisdec: reject rangebits 0 with non-0 partitionsAndreas Cadhalpun
This causes non-unique elements in floor_setup->data.t1.list, which makes the stream undecodable according to the specification. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

2013-05-20vorbis: fallback to normal division instead of crashingLuca Barbato
The use of ff_inverse speeds up slightly arches + compilers that do not provide a division faster than the whole machinery, such as ppc32 + gcc4.7, but has operational limits. Drop the always-enable assert and provide a fallback.
