Bug 1656854 - Part 2: Add a BrowsingContextGroup keepalive to BrowserParent shutdown, r=farre In bug 1652085, I added BrowsingContextGroup keepalives while waiting for replies to the discard message, however that message isn't actually sent to the current owner process. Instead, the BrowsingContext is discarded by the PBrowser being destroyed. This should help ensure we also keep the group alive during normal BrowserParent destruction. Differential Revision:

 * Sort the contents of the widget containing <code>aNode</code>

 * @param aNode A node in the XUL widget whose children are to be sorted.
 * @param aSortKey The value to be used as the comparison key.
 * @param aSortHints One or more hints as to how to sort:
 *   ascending: to sort the contents in ascending order

 *   comparecase: perform case sensitive comparisons
 *   integer: treat values as integers, non-integers are compared as strings
