This fixes all the license headers in the main library, which corrects
the appearance of the main license in the compiled output.
It seems that the `!` in the header forces the compiler to keep it in
the output. I believe older compiler releases did this purely based
on `@license`.

@exportInterface is used by the extern generator, but ignored by the
compiler. @export should be used for shaka.util.FairPlayUtils and
shaka.util.BufferUtils.
Closes#2626 and #2627
The 'webkitkeyneeded' and 'encrypted' events send similar data, but
they were incompatible with each other and our transform handling.
This makes our polyfill produce the same format as the browser for
cases where the browser may only fire the old event. This also makes
our utilities work with the new format.
The 'webkitkeyneeded' event was a length-prefixed UTF-16 string while
the 'encrypted' event was just a UTF-8 string.
This also makes a breaking change in the transform callback to pass the
init data type. This shouldn't break anyone that only uses the first
argument; the second argument was mainly added so we could have the
default transform work without knowing anything.
This change could also break people who use custom transform functions.
The init data format is changing, which could break people who read
it directly. If they follow the tutorial and use our utilities, it
shouldn't break. This also updates the tutorial to match the new format
and be more clear about the format.

This reflects changes in Google's policy on JavaScript license
headers, which should be smaller to avoid increasing the size of the
binary unnecessarily.
This also updates the company name from "Google, Inc" to "Google LLC".

Using "new Uint8Array" with a TypedArray creates a copy of the buffer;
this is unnecessarily expensive for large buffers. This adds a rule
to disallow using it in favor of a new utility that correctly creates
a new "view" on the same buffer.
Note it is fine to pass an ArrayBuffer to "new Uint8Array" and it won't
copy; but there there are many cases where the type is BufferSource,
so it could be a TypedArray. Unfortunately, there are many other cases
where we explicitly pass an ArrayBuffer; but the compiler rules don't
allow us to whitelist this case (since ArrayBuffer is part of
BufferSource).

This changes the network API to use BufferSource instead of ArrayBuffer,
which allows plugins to return a "view" on a buffer instead of the
whole buffer. This also adds some utilities for changing between
views and buffers.
Lastly this forbids the use of the "buffer" property of TypedArrays
since it doesn't work with partial "views". This audits and fixes the
usages of the "buffer" property to ensure correct usage.
It should be noted that both MSE and EME accept a BufferSource as input,
so we don't need to convert a "view" into an ArrayBuffer before passing
to it.

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.
