As part of Period-flattening, I'm trying to remove our dependence on
the "position" field of SegmentReference. With that eliminated, we
can more easily concatenate Arrays of SegmentReferences without
modifying them.
- Make SegmentIndex iterable
- Add specialized seek() and current() methods to SegmentIterator
- Remove position from SegmentReference
- Make positions in SegmentIndex API stable without field in
reference
- Remove brittle hard-coded positions in tests (except SegmentIndex
tests, where they would be hard to avoid in testing methods
separately)
- Use SegmentIterator in StreamingEngine to track the next segment
between switches

This is a step along the way to flattening periods, and also

SegmentReference used to have presentationTimeOffset, which,
subtracted from the period start time, was then _added_ to the
timestamps in the segment by MediaSource.
Now, SegmentReference has a timestampOffset field, which is exactly
what MediaSource's timestampOffset field is set to on the SourceBuffer
before this segment is appended. For DASH, this is periodStart minus
presentationTimeOffset.
This also adds append window start & end times to the
SegmentReference. Now segments can be appended to SourceBuffers
without reference to the period.
Note that start & end times of the SegmentReference in each segment
index are still relative to the period. This will change in a
follow-up.

Now there is a generic callback to transform the init data before
passing it to the browser. This can be used by apps to use a custom
content ID in FairPlay content. This also adds some utilities to help
in writing these functions and moves the default behavior to DrmEngine.

To prepare for flattening out the manifest structure to remove
periods, this change moves initSegmentReference and
presentationTimeOffset fields into the SegmentReference object. This
way, the segments on either side of a period transition or HLS
discontinuity can have different offsets or init segments, eventually
allowing us to create a single array of SegmentReferences for
multi-period content.

This replaces find/get callbacks in Stream with a SegmentIndex. With
the exception of DASH's SegmentTemplate+duration, all manifests were
already backed by SegmentIndex. Now, all manifests are backed by
SegmentIndex. This will simplify Period-flattening, in which all
tracks will be represented by a list of segments, some of which come
from different Periods.
The SegmentIndex in Stream will not be created until
createSegmentIndex is called. Prior to this change, the find/get
callbacks could be invoked without createSegmentIndex() in some cases
(excluding DASH's SegmentBase), which some lazy tests took advantage
of. Now that find/get are methods on SegmentIndex, createSegmentIndex
must be called in all cases. The tests have been updated accordingly.
Making SegmentIndex generation async in all cases exposed some issues
with the parser context being modified in-place between one
Representation and the next. So the parser now makes a shallow copy
of the context before it is bound into an async callback.
To facilitate updating the SegmentIndex for SegmentTemplate+duration
content, SegmentIndex now has a method to update its list on a timer.
Once per segment duration, the index will be updated to add and remove
SegmentReferences.
The initial expansion of SegmentTemplate+duration will be limited to a
relatively small number of segments, to avoid excessive CPU or memory
consumption. This defaults to 1000 segments, but is configurable.

The controls have the cast proxy and the proxied player, so the UI
itself offering direct access to the local player is confusing.
Instead, we will send all requests through the controls, which have
explicit getPlayer() and getLocalPlayer() methods for access to the
proxied and local players.

This updates our build requirements to NodeJS v8+ and NPM v5+, both
released in 2017.
This also clarifies our support for Python 3 (not well-documented
before) to the version we are using on Debian, v3.5.
Requiring NodeJS v8+ means our node tools (like our extern generator)
no longer need shims for compatibility. This allows us to drop the
"es6-shim" and "array-includes" modules.
In NPM v5+, the "prepublish" script has been deprecated, and replaced
with "prepublishOnly" (which is what we want) and "prepare" (the old
behavior we had to work around). This allows us to drop the
"in-publish" module.

This reduces the number of resources we have to load by using LESS to
import them into the compiled CSS bundle.
This also gets rid of a flash of unstyled content in compiled mode by
always including the compiled CSS in HTML directly, regardless of
mode. If the app is running in uncompiled mode, LESS is still loaded
and can override the compiled styles.

Jsdoc has the `@link` syntax for links, but github's markdown renderer
sees the closing curly brace as part of the link.
To format things in a way that works for both jsdoc and github, we
should specify text for the `@link` as well as the link itself. This
separates the URL from the enclosing curly braces in a way that fixes
github's rendering of the markdown.
