If the back button is used to navigate a tab backwards in its history, and then the tab is closed,
the current implementation of sessions.getRecentlyClosed does not take this into account and
just uses the last item in the tab history for the values returned for the tab. This patch fixes
this by using the values for the current position of the tab in its history.

Currently tabs.onActivated (for the tab that becomes active after a tab is removed) fires before
tabs.onRemoved (for the tab that was removed). This is neither the order in which Chrome fires
these events, nor is it the order in which the internal TabSelect and TabClose happen in Firefox.
This bug fixes this so tabs.onActivated fires *after* tabs.onRemoved.
Note that this does introduce an issue in in-process mode, where window.close() will not
trigger a tabs.onRemoved event for the window, but Kris says "Meh" about that.

In order to rewrite the Gecko Profiler add-on as a WebExtension,
we need an API for the profiler which allows us to control the
nsIProfiler, and symbolicate the stacks that it provides. This
is the implementation of the simpler parts of that API.
TODO:
- Support profiling of remote targets through a new devtools
API.
- Support the dump_syms breakpad code which was asm.js in the
old extension by directly calling into native code.
- Figure out a faster way to send the large volume of data from
getSymbols all the way from our extension down to the content
process and then into the page's context.
