mkvmuxerutil: Revert to using mkvmuxertypes.

Browse Source 
- The direct change to stdint.h types causes too much downstream
  churn. Need an intermediate step or a wrapper because quite a
  bit of user code explicitly casts args passed to mkvmuxerutil
  functions to types defined in mkvmuxertypes.
- Update call sites in mkvmuxer to avoid ambiguity errors.
