- intfloat_readwrite: fix signed addition overflows · 88d1e2b2
  Mans Rullgard authored Oct 08, 2011
```
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.

- h264: fix detection of optional trailing PPS elements · be1242a3
  Mans Rullgard authored Oct 10, 2011
```
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.

The way this value is used, it should be an unsigned type.
