a62c0f94ee adpcmdec: calculate actual number of output samples for each decoder. 
This also allows for removing some of the buf_size checks and using the
sample count for some of the decoding loops.

ff5790c761 adpcmdec: do not terminate early in ADPCM IMA Duck DK3 decoder.

read. Updated FATE reference.

d341d5fd2c dnxhdenc: fixed signed multiplication overflow 
The low 32 bits of a multiplication are the same for signed
and unsigned operands.  Casting to unsigned before multiplying
is thus equivalent while avoiding signed overflow, which is
undefined by the C99 standard.

b45eb9d619 pcm: reduce pointer type casting 
Making 'samples' a pointer to uint8_t simplifies the DECODE
macro and reduces the amount of type casting overall.

This also fixes some signed overflows on left shift.

f59bb3d8f3 mathops: remove undefined behaviour from sign_extend() 
This function intentionally overflows the signed range on
the left shift.  Using this type-punning avoids errors from
the overflow checker without disabling this test globally.

reset for progressive frame after interlaced one causing writing past the

641c7afe3c AVOptions: add new API for enumerating children. 
This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)

This will also allow the new setting/reading API to transparently apply
to children contexts.

c682514a8f qdm2: fix signed multiplication overflow 
This code relies on the result wrapping as for unsigned

fdba370f8a h264: fix HRD parameters parsing 
The bit_rate_value_minus1 and cpb_size_value_minus1 elements
allow a wider range than get_ue_golomb() supports.  This
adds a get_ue_golomb_long() function supporting up to 31
leading zeros, which is the maximum for these syntax
elements, and uses it in decode_hrd_parameters().

those cases where the value is not used.  Moving the calculation
