This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <![CDATA[, """ or '''. The first two
cover comments, the third one covers JS, the fourth covers JS embedded
in XUL, and the final two cover JS embedded in Python. This also
applies if the removed line was the first line of the file.
It covers the pattern matching cases like "var {classes: Cc,
interfaces: Ci, utils: Cu, results: Cr} = Components;". It'll remove
the entire thing if they are all either Ci, Cr, Cc or Cu, or it will
remove the appropriate ones and leave the residue behind. If there's
only one behind, then it will turn it into a normal, non-pattern
matching variable definition. (For instance, "const { classes: Cc,
Constructor: CC, interfaces: Ci, utils: Cu } = Components" becomes
"const CC = Components.Constructor".)

It seems to be possible for an inner-window-destroyed notification to be dispatched
after xpcom-shutdown. This means that communications over the Services.cpmm are
attempted after the connection to the parent process has already been torn down. This
can cause an Exception to be thrown, which can keep the ContentProcessMessageManager
alive long enough to cause SpiderMonkey to complain that there are still living
elements in its heap at JS shutdown time.

Crash reporting for GMPs being used from the EME call site are not generating
crash reports because they depend on the MediaKeys object calling
GMPService::AddPluginCrashHandler() to associate a window to which the
PluginCrashedEvent is fired. This doesn't work with e10s enabled because the
GMPParent which causes the plugin crash handlers to run is in the chrome
process, but the MediaKeys which adds the handler is in the child process. So
the crash handler is on the GMPServiceChild, but we only run the crash handlers
that were added to the GMPServiceParent in the chrome/parent process.
The solution is to broadcast a message from the chrome process to all the
content processes when a GMP has crashed that causes the GMPServiceChild to
also run its crash handlers.
