3cf21bd5d5 Require the list returned by SubtitleParser to be sorted by timestamp 
This makes it more efficient to consume (e.g. we can binary search
through it).

f4bf376e89 Defer outputting the metadata sample when TimestampAdjuster isn't initialized 
The sample timestamp carried by the emsg box can have a significant delta when comparing to the earliest presentation timestamp of the segment. Using this timestamp to intialize the timestamp offset in TimestampAdjuster will cause the media sample to have a wrong adjusted timestamp. So we should defer adjusting the metadata sample timestamp until the TimestampAdjuster is initialized with a real media sample.

When seeking in fMP4, we try to extract as little samples as possible
by only starting at the preceding sync frame. This comparison should
use <= to allow sync frames at exactly the seek position.

3efc62b512 Deprecate C.POSITION_UNSET in favour of C.INDEX_UNSET 
These have the same value (`-1`), and basically the same meaning (offset
in an array/list/file/byte stream/etc), but 'position' is an overloaded
term in a media playback library, and there's a risk people assume that
methods like `Player.getCurrentPosition()` may return
`C.POSITION_UNSET`, when in fact unset media times (whether duration or
position) are always represented by `C.TIME_UNSET` which is a) a `long`
(not `int`) and b) a different underlying value. (aside:
`getCurrentPosition()` never returns an unset value, but it's a good
example of the ambiguity of the word 'position' between 'byte offset'
and 'media timestamp'.)
