video: Add VideoTimeCode bindings

Browse source 
There's a VideoTimeCode type that represents any kind of timecodes,
including invalid ones, and which allows to change each field
individually. And ValidVideoTimeCode that has all fields
validated and that can be used with most of the API.

In C, validation of the timecodes is left to the user and most functions
assert on getting passed valid timecodes.
