The reasoning behind this is that with this change, removing a non-dynamic
docshell from the document dynamically shouldn't affect the indexes which we use
for both recording and restoring data in child docshells.

The intermittent failure is caused by the innate drawback of the present test,
it doesn't be consistent with the behavior how we actually block the media.
Since we always block media implicit, it would be set in nsGlobalWindow's ctor.
We would never call blockMedia directly, so we can remove the function.

Pinned tabs, when restored, load. This can have startup impact.
We should probably measure this.
To avoid impacting startup ourselves, do this when idle or after 60s from
session restore, whichever comes first.

If the tab was resumed before, it could start playing any autoplay media without user's
permission after session restore.

The browser-chrome test suite now detects and reports unhandled rejections of native Promises, in addition to those created by Promise.jsm. The whitelisting mechanism is updated to use primarily the PromiseTestUtils.expectUncaughtRejection function. Tests will fail if a rejection that is not whitelisted occurs, or if a whitelisted rejection does not occur anymore.

We currently show a full URL as the initial tab title (e.g. "https://www.mozilla.org/en-US/") until the page loads and we know the actual page title. When loading multiple tabs, such as during session restore, many tabs will have the same undifferentiated tab title prefix like "https://www....". Since the URL scheme and "www." subdomain are not meaningful to users, just show the URL's hostname without any "www." prefix (e.g. "mozilla.org").
Other browsers' initial tab titles for comparison:
* Firefox 54 uses "Connecting...".
* IE11 uses the same "hostname without www" placeholder as this changeset.
* Edge uses "Blank page".
* Chrome uses "Loading..." on Windows and "Untitled" on Mac.
* Safari uses "Untitled".

This test case documents the current behavior of about: pages's initial tab titles. The fix for bug 1364127 caused about: pages' initial tab titles to show their about: URIs until their actual page titles are known, e.g. "about:addons" -> "Add-ons Manager". This is bug 1371896. Previously, about: pages' initial tab titles were blank until the page title was known.
This test case uses the about:robots page because its title is not localized, which makes testing easier.

DevTools are moving out of mozilla-central and m-c code should only rely on the
DevToolsShim that will remain available in m-c after the migration.
This changeset updates SessionStore.jsm to call the DevToolsShim instead of the
scratchpadmanager.
The actual underlying implementation is the same when devtools are installed and
no-ops when they are not.
