clang's -Wmissing-prototypes option identifies global functions that can be made static (because they're only called from one compilation unit) or removed (if they're never called). The .cpp files defining these functions did not include the headers with the corresponding function prototypes used by other compilation units. Including a header file in its corresponding .cpp file can help catch mismatched declarations and definitions.
xpcom/components/nsCategoryManager.cpp:637:6 [-Wmissing-prototypes] no previous prototype for function 'NS_CreateServicesFromCategory'

Nearly all of the consumers of category enumerators require the entry value,
either along with or instead of the name. Including both by default simplifies
things considerably for most consumers, and allows us to remove the XPCOMUtils
wrapper that JS callers typically use to enumerate category entries.

This allows JS callers to automatically get the correct types during
interation, without having to explicitly specify them.

In order to allow JS callers to use nsISimpleEnumerator instances with the JS
iteration protocol, we'll need to additional methods to every instance. Since
we currently have a large number of unrelated implementations, it would be
best if they could share the same implementation for the JS portion of the
protocol.
This patch adds a stub nsSimpleEnumerator base class, and updates all existing
implementations to inherit from it. A follow-up will add a new base interface
to this class, and implement the additional functionality required for JS
iteration.

Much like the component manager, many of the strings that we use for category
manager entries are statically allocated. There's no need to duplicate these
strings.
This patch changes the category manager APIs to take nsACStrings rather than
raw pointers, and to pass literal nsCStrings when we know we have a literal
string to begin with. When adding the category entry, it then skips making
copies of any strings with the LITERAL flag.

This patch removes checking of all the callback calls in memory reporter
CollectReport() functions, because it's not useful.
The patch also does some associated clean-up.
- Replaces some uses of nsIMemoryReporterCallback with the preferred
nsIHandleReportCallback typedef.
- Replaces aCallback/aCb/aClosure with aHandleRepor/aData for CollectReports()
parameter names, for consistency.
- Adds MOZ_MUST_USE/[must_use] in a few places in nsIMemoryReporter.idl.
- Uses the MOZ_COLLECT_REPORT macro in all suitable places.
Overall the patch reduces code size by ~300 lines and reduces the size of
libxul by about 37 KiB on my Linux64 builds.

This patch adds an assertion that makes sure that the nsCategoryManager is
destroyed after the nsMemoryReporterManager, because bad things would happen
otherwise.
Also, nsCategoryManager uses manual memory management (it's AddRef/Release are
hardwired to always return 2 and 1 respectively) so it doesn't matter if we
register it as a strong or weak memory reporter. But it's more common to use
RegisterWeakMemoryReporter when the argument is |this|, so this patch does
that.

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.

And we still have the existing single-arg SizeOf{In,Ex}cluding() functions,
which work if the entry type itself defines SizeOfExcludingThis().

They are kept around for the sake of the standalone glue, which is used
for e.g. webapprt, which doesn't have direct access to jemalloc, and thus
still needs a wrapper to go through the xpcom function list and get to
jemalloc from there.
The nsCategoryManager singleton lives until very late in shutdown, so the unregister always fails.
It is okay to make it a strong reporter because it will always outlive the memory reporter manager anyways.
