The compartment-per-addon code was added so that we could segregate at least
some of the code from system-privileged add-ons into tagged compartments, even
when it ran in browser windows. That allowed us to apply certain special
behavior to them, such as enabling e10s shims, and to track some performance
characteristics.
The only remaining chrome-privileged add-ons now are system add-ons controlled
by us, and the shim system and per-compartment performance metrics are gone,
it no longer serves a purpose.

This allows us to specifically whitelist browser mochitests which still rely
on unsafe CPOWs, and run them in a separate Sandbox global with permissive
CPOWs enabled.
The test harness and most of the in-tree tests will run with permissive CPOWs
disabled, like the rest of the browser.

This patch also checks for I/O errors when deleting leftover crashdump files
in the test harness and reports them if the files couldn't be deleted. This
won't prevent tests from leaking crash dumps if they're not written correctly,
but it will make their presence visible and won't cause the harness to hang if
it cannot delete them.

This adds a global instance that can be used by invoking assertion methods directly on the imported Assert object. The test suites set the global reporter function to the one for the currently running test.

This patch re-organizes control flow in the browser-chrome harness so that
extra memory cleanup only happens just before the browser is closed, even
when running with --repeat.
Overriding Services.scriptloader has a lot of consequences in terms of path
name magling and choice of target global when no target object is passed.
Since this test code doesn't care about callers outside of XPCOMUtils, it
should only override the instance used by XPCOMUtils, and not the instance
used by other callers.

The whitelisting function thisTestLeaksUncaughtRejectionsAndShouldBeFixed was replaced by expectUncaughtRejection, and existing calls did not take effect anymore.

The mochitest harness uses testEnd multiple times to log various failures. This can result
in several testEnd messages, which will soon cause mozlog to spit out an error. Instead,
these should be testStatus.
This also starts using mozlog's assertion_count log action to log test assertions (again,
instead of testEnd).

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.

The browser-chrome self-test files now use the setExpectedFailuresForSelfTest function to specify the exact number of assertion failures that will be triggered. Also, most failures are now intercepted when specifying the "fail-if" property in a "browser.ini" manifest, while previously only those triggered using the "ok" function were intercepted. This allows re-enabling several browser-chome self-tests.
