Replace uses of raw uint32's with a type-checked RtpTimeTicks data type.

Introduces RtpTimeDelta and RtpTimeTicks to media::cast, modeled after
base::TimeDelta and base::TimeTicks, that track RTP time and provide a
strict set of valid math and comparison operators, bit truncation and
re-expansion, and timebase conversion.

All instances of raw uint32 used to represent RTP timestamps has been
replaced with the new data type.
