KongQun Yang 55050fe6b5 [Ad Insertion] Avoid adjusting EPT except for the first file
EPT (earliest presentation time) may be adjusted not to be lower than
the decoding timestamp (dts), but the adjustment should only be done
on the first file when there is one file per Representation per Period.
The second file and onwards should not be adjusted otherwise a GAP
would be created.

Closes #384
Closes b/78517422

KongQun Yang 772aa7c93f Do not force earliest_presentation_time to 0 for VOD
Instead, the actual earliest presentation time is used except for
the first segment if there is an offset between presentation time
(pts) and decoding time (dts).

Chrome (as of v66) reports dts instead of pts in buffered ranges in
MSE API. To avoid breaking Chrome, the earliest_presentation_time
of the first segment is set to its dts as Chrome does not like negative
values for
  adjusted dts = dts + Period@start (0 for the first period)
                 - presentationTimeOffset (earliest_presentation_time).

Fixes #303.

Aaron Vaage 16eff80497 Made StreamData Have Const Pointers
In prep for changes to Trick Play, we want to make all messages
copy on write so that if the same message is sent to multiple
handlers, it is not possible for one handler to change the data
another handler is using.
