Uint8Array is more flexible because it can refer to a subrange within
a bigger ArrayBuffer.
This is a more natural fit and avoids the copy in symbolicator-cli.

Having this config outside of package.json is consistent with the rest
of our configurations. It also lets us add comments.

And it will make it easier to add other test environments, for example
if we want to test how code runs in a pure node environment rather than
in the browser-like environment.
…fer (#5678)

Accepting an ArrayBuffer is a bit restrictive because it means the
buffer has to be sized to exactly contain the profile bytes and nothing
else. Accept a Uint8Array is more flexible because the Uint8Array can
refer to just the sub-part of the buffer that actually contains the
profile.

This lets us avoid a copy in symbolicator-cli.

This replaces the webpack plugin with an invocation of the `workbox` CLI
binary.

I went ahead and checked if the Map or Set objects had unknown types at
the time of their declaration in the language server. These are the
things I found.

This fixes #5617.

…5712)

Initially `unpublished` was an alias of `from-addon` and then it was
made a separate data source. But reloading the url or loading from
scratch was hanging in the profile loading animation indefinitely and it
wasn't trying to load any profile either. It makes sense to make it
behave more like `from-file` in that sense and just redirect to the home
page.

Issue #5709 has an STR for this bug.
….json (#5714)

2 changes:
- make the content of event.args.detail visible on markers (this shows
which source file is being processed)
- isMainThread = true when pid == tid (will work only on Linux, but will
still be a big relief there to have the actually useful thread at the
top)

This was causing all of react to be bundled into the symbolicator-cli script.
