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.
Mark _BitScanReverse as an intrinsic, as this is not done by default
in _DEBUG mode (thanks to Bjoern D. Rasmussen for the suggestion).
Move the declaration of ec_ilog() to where the macro using it is
defined, to ensure it is available when the macro is used.
Thanks to John Ridges for the report.
