2f072b55a4 Fix the conversion of AV_SAMPLE_FMT_FLT and _DBL to AV_SAMPLE_FMT_S32. 
(1<<31) is undefined and seems to be evaluated by gcc to -2^31 when
these formulae require 2^31.

These conversions still need fate tests.

187a537904 Convert some undefined 1<<31 shifts into 1U<<31. 
According to ISO 9899:1999 S 6.5.7/4:

The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the
result is E1× 2^E2, reduced modulo one more than the maximum value
representable in the result type. If E1 has a signed type and
nonnegative value, and E1× 2^E2 is representable in the result type, then
that is the resulting value; otherwise, the behavior is undefined.

029f966c3a g722: Return 8 bits per sample for g722 in av_get_bits_per_sample 
This fixes a failing assert in ff_raw_read_header (in
fate-g722dec-1), where bits_per_coded_sample is set using this
function and is required to have a positive value.

cf39b461d3 pthread: validate_thread_parameters() ignored slice-threading being intentionally off 
The thread_type API allows you to request only FF_THREAD_FRAME (instead of
FRAME | SLICE), but it was being ignored.
We don't implement both of them at the same time, so there isn't an effect
on current codecs, except that you can request no kinds of threading now
(a bit useless).

ba9ef8d04e Remove unnecessary parameter from ff_thread_init() and fix behavior 
thread_count passed to ff_thread_init() is only used to set AVCodecContext.
thread_count, and can be removed. Instead move it to the legacy implementation
of avcodec_thread_init().

This also fixes the problem that calling avcodec_thread_init() with pthreads
enabled did not set it since ff1efc524c.
