Bug 1682442, prioritize tab unloader based on how many processes are used by a tab, how much memory is used by the tab, and whether sound/webrtc/picture in picture is in use for a tab, r=gsvelto

Details | Review

Improve it by weighting tabs by more criteria that better ensure tabs that close on low memory or low process-count are selected based on those less likely to affect the user.

The patch above now prioritizes unloading tabs based on whether the tab is selected, pinned, playing sound, using picture-in-picture or using webrtc. It modifies the priority of a tab to close based on how many processes might be stopped if the tab is closed, or a guess at how much memory would be freed up if the tab was closed.
