c682514a8f qdm2: fix signed multiplication overflow 
This code relies on the result wrapping as for unsigned
values, and the sign is not used.  Thus an unsigned type
is proper here.

5e87222fd1 flvdec: Don't export metadata entries that aren't proper metadata 
This avoids writing these entries doubly if transcoding from
flv to flv, since the muxer blindly writes any and all metadata
keys set, in addition to the fixed fields that the muxer
always writes.

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().

8babfc033e h264: fix invalid shifts in init_cavlc_level_tab() 
The level_code expression includes a shift which is invalid in
those cases where the value is not used.  Moving the calculation
to the branch where the result is used avoids these.

88d1e2b2b0 intfloat_readwrite: fix signed addition overflows 
These additions might overflow the signed range for large
input values.  Converting to unsigned before the addition
rather than after avoids such undefined behaviour.  The
result under normal two's complement wraparound remains
unchanged.

be1242a3f2 h264: fix detection of optional trailing PPS elements 
The PPS may contain a few trailing elements whose presence is
only signalled by data remaining after the the mandatory part
has been parsed.  The current code fails to take into account
the rbsp_trailing_bits() when deciding whether to parse these
optional elements.  Assuming no unnecessary padding bytes are
passed to this function, the optional elements are present if
either more than 8 extra bits remain or the remaining bits do
not form a valid rbsp_trailing_bits() after the mandatory PPS
elements have been parsed.
