NS_InitXPCOM() is currently not called in Gecko. It has been a one-line wrapper around NS_InitXPCOM2() since the year 2000 (bug 46320), presumably to maintain ABI compatibility for third-party users of XPCOM. We no longer need to worry about XPCOM ABI compatibility.

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 only difference between ShutdownLoaders and ShutdownFinal was an observer service shutdown.

This commit adds categories to all markers. This way the profiler's
marker categories and frame label categories agree. There are a few
duplicate category properties on some of the marker payloads, but
this could be cleaned up in a follow-up if needed.

vpx_mem_set_functions support is only enabled when
MOZ_VPX_NO_MEM_REPORTING is not set. It is currently set unconditionally
when building with the in-tree libvpx. When building with system libvpx,
it is set when the vpx_mem_set_functions can't be found in the system
libvpx library.
Upstream removed the vpx_mem_set_functions function in version 1.5, and
we require at least that version, meaning, in practice,
MOZ_VPX_NO_MEM_REPORTING is now always set.
We might as well remove the define and the code that's conditional to
not being defined.

After the previous patches, we no longer rely on the component manager
to incidentally start up XPConnect when we load the JS loader service
or to hold the JS component loader alive, so the do_GetService() call
for the JS loader in XPCOMInit.cpp can be removed. After that is done,
the JS loader is no longer used as an XPCOM component, so all of the
boilerplate for that can be removed.

JS is the only file extension actually supported, and there are a few
layers of cruft that can be eliminated if we specialize it.
This eliminates one XPCOM registration of the JS component loader.

The NS_NewTimer* family of functions, when using a custom event target,
currently go through a path that looks something like:
auto timer = createTimer()
timer->SetTarget(target);
// call the requisite Init* function
return timer;
This setup is inefficient, because SetTarget requires the timer mutex to
be acquired. The mutex acquisition here is completely unnecessary,
because the timer hasn't yet been shared out to the wider world; we can
set the timer target without acquiring the mutex at all because we know
that no sharing is possible at this point.
This patch reworks things somewhat to make that possible.
Static atom registration is a bit of a mess. NS_InitAtomTable() calls
nsGkAtoms::RegisterStaticAtoms(), which calls NS_RegisterStaticAtoms(); i.e. we
go from nsAtomTable.cpp to nsGkAtoms.cpp and back.
(And NS_RegisterStaticAtoms() is declared in a .cpp file, not a .h file!)
This commit makes NS_InitAtomTable() a friend of nsGkAtoms, so NS_InitAtomTable
can see nsGkAtoms's atoms array directly, thus removing the need for
NS_RegisterAtomTable() and nsGkAtoms::RegisterStaticAtoms().
This commit also removes an out-of-date part of a comment from XPCOMInit.cpp.

As initially implemented, nsITLSServerSocket by default enabled the use of the
TLS session cache provided by NSS. However, no consumers of nsITLSServerSocket
actually used it. Because it was an option, though, PSM had to jump through some
hoops to a) make it work in the first place and b) not have NSS panic on
shutdown. Furthermore, it meant increased memory usage for every user of Firefox
(and again, nothing actually used the feature, so this was for naught).
In bug 1479918, we discovered that if PSM shut down before Necko, NSS could
attempt to acquire a lock on the session cache that had been deleted, causing a
shutdown hang. We probably should make it less easy to make this mistake in NSS,
but in the meantime bug 1479918 needs uplifting and this workaround is the
safest, most straight-forward way to achieve this.

Fairly straightforward, just a blanket removal. Haven't heard
anything on dev-platform or fx-data-dev regarding this removal,
so I think it's likely safe to remove on Nightly, and we can
revert if anyone makes a fuss.
As part of removing the HangMonitor, I renamed a few things and
reorganized the namespaces to not depend on a HangMonitor
namespace. Hopefully this doesn't produce too much noise in the
diff, it just seemed appropriate to move everything around
rather than keep dangling vestiges of the old system.
