This change avoids lots of false positives for Coverity's CHECKED_RETURN
warning, caused by NS_WARN_IF's current use in both statement-style and
expression-style.
In the case where the code within the NS_WARN_IF has side-effects, I made the
following change.
> NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
> -->
> Unused << NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
In the case where the code within the NS_WARN_IF lacks side-effects, I made the
following change.
> NS_WARN_IF(!condWithoutSideEffects);
> -->
> NS_WARNING_ASSERTION(condWithoutSideEffects, "msg");
This has two improvements.
- The condition is not evaluated in non-debug builds.
- The sense of the condition is inverted to the familiar "this condition should
be true" sense used in assertions.
A common variation on the side-effect-free case is the following.
> nsresult rv = Fn();
> NS_WARN_IF_(NS_FAILED(rv));
> -->
> DebugOnly<nsresult rv> = Fn();
> NS_WARNING_ASSERTION(NS_SUCCEEDED(rv), "Fn failed");

This patch makes the following changes on many in-class methods.
- NS_IMETHODIMP F() override; --> NS_IMETHOD F() override;
- NS_IMETHODIMP F() override {...} --> NS_IMETHOD F() override {...}
- NS_IMETHODIMP F() final; --> NS_IMETHOD F() final;
- NS_IMETHODIMP F() final {...} --> NS_IMETHOD F() final {...}
Using NS_IMETHOD is the preferred way of marking in-class virtual methods.
Although these transformations add an explicit |virtual|, they are safe --
there's an implicit |virtual| anyway because |override| and |final| only work
with virtual methods.

This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.
As a result of these changes, I had to add |override| to a couple of other
functions to satisfy clang's -Winconsistent-missing-override warning.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

Because DMD is no longer just about measuring memory reports coverage, but is
also used for more general heap profiling.

This also effectively changes how DMD is enabled from requiring both
replace-malloc initialization and the DMD environment variable to
requiring only the former. The DMD environment variable can still be
used to specify options, but not to disable entirely.
This however doesn't touch all the parts that do enable DMD by setting
the DMD environment variable to 1, so the code to handle this value
is kept.
The interesting feature JSONWriteFunc has, contrary to JSONWriter, is that it
only has virtual methods, which makes it a better candidate to be passed
around between libraries not linked against each other.
This will allow to make dmd and libxul independent from each other.
The patch also adds DMDAnalyzeReports() as a synonym for DMDReportAndDump(),
and deprecates the latter.

This has a few semi-interdependent pieces:
* Factoring out the file opening/closing/renaming from the GC/CC logging.
* Using IPC to have the child log to files that the parent opened.
* Changing nsIMemoryInfoDumper.dumpGCAndCCLogsToFile to report completion
of child process logging (which was impossible before this, and which is
needed to have a meaningful test case).
* Changing about:memory to dump logs for child processes, matching the
behavior of the "Measure" button, because it can tell the user where
they are now.
* Add a test for multiprocess GC/CC log dumping (only of the XPCOM
interface, not by clicking buttons and scraping the about:memory page,
but done as a chrome mochitest to start remote browsers); based on
test_memoryReporters2.xul in the same directory.
