We only use nsINamed on runnables for certain kinds of telemetry, and
those kinds of telemetry aren't being gathered on RELEASE_OR_BETA
builds. We effectively make nsINamed::GetName a no-op when we're not
collecting said telemetry. But implementing nsINamed does have a cost:
the vtable of every runnable (and we have hundreds of subclasses of
mozilla::Runnable) will contain pointers for GetName (and extra pointers
for QueryInterface/AddRef/Release), and all those pointers times all
those subclasses adds up quickly. Let's not implement nsINamed when
nsINamed isn't going to be used.
This change saves ~100K of binary size on x86-64 Linux; the savings
should be similar on other 64-bit systems, and ~50K on 32-bit systems.
nsGkAtoms::Home and nsDirectoryAtoms::sOS_HomeDirectory are duplicate static
atoms. This patch comments out the latter to remove the duplication.

For bug 1438688, I need to statically initialize all of the data types
in xpt_struct.h. It turns out that the approach I was using for unions
is C99 and not C++. While for some reason Clang and GCC are okay with
that, MSVC is not.
One of the unions is a gnarly anonymous union in
XPTTypeDescriptor. However, every arm of this union is either 1 or 2
uint8_t, so I think it is reasonable to eliminate the union and
replace it with two fields, mData1 and mData2. I've fixed up the
places that read this data to use accessor methods with nice asserts
about the tag on the variant, so if anything I think that part is
nicer.
The code in xpt_struct.cpp that writes to this data is maybe less
nice, but I'm deleting it in bug 1438688 so I think that's okay. We
also lose some detail in the comments about the relationship between
what is stored in memory compared to what is stored on disk, but I
think that's okay, too.

We risk a shutdown hang without any clues if a dangling reference somewhere
keeps a SharedThreadPool alive past xpcom-shutdown-threads. This because
xpcom-shutdown-threads waits for all SharedThreadPool to be destroyed before
advancing shutdown further. nsCycleCollector::Shutdown comes after
xpcom-shutdown-threads so it is possible that a reference-cycle unexpectedly
keeps a SharedThreadPool alive and blocks shutdown indefinitely.
This patch attempts to help diagnose future cases like this by printing which
SharedThreadPools we are going to wait for to stderr.

In SourceSurfaceImage::GetTextureClient, we use LookupForAdd. This is
because we typically will create a new TextureClient if there isn't
already one created. This creation can fail because the size is too big,
or we don't have the memory available for it. Unfortunately LookupForAdd
is an infallible operation; it is expected we will always add something

This patch replaces the large -intPrefs/-boolPrefs/-stringPrefs flags with
a short-lived, anonymous, shared memory segment that is used to pass the early
prefs.
Removing the bloat from the command line is nice, but more important is the
fact that this will let us pass more prefs at content process start-up, which
will allow us to remove the early/late prefs split (bug 1436911).
Although this mechanism is only used for prefs, it's conceivable that it could
be used for other data that must be received very early by children, and for
which the command line isn't ideal.
Notable details:
- Much of the patch deals with the various platform-specific ways of passing
handles/fds to children.
- Linux and Mac: we use a fixed fd (8) in combination with the new
GeckoChildProcessHost::AddFdToRemap() function (which ensures the child
won't close the fd).
- Android: like Linux and Mac, but the handles get passed via "parcels" and
we use the new SetPrefsFd() function instead of the fixed fd.
- Windows: there is no need to duplicate the handle because Windows handles
are system-wide. But we do use the new
GeckoChildProcessHost::AddHandleToShare() function to add it to the list of
inheritable handles. We also ensure that list is processed on all paths
(MOZ_SANDBOX with sandbox, MOZ_SANDBOX without sandbox, non-MOZ_SANDBOX) so
that the handles are marked as inheritable. The handle is passed via the
-prefsHandle flag.
The -prefsLen flag is used on all platforms to indicate the size of the
shared memory segment.
- The patch also moves the serialization/deserialization of the prefs in/out of
the shared memory into libpref, which is a better spot for it. (This means
Preferences::MustSendToContentProcesses() can be removed.)

A lot of our thread pools use the default stack size for the platform
they're on, which can be rather large (8MB, usually, on Linux and OS X)
and is probably too much for the typical thread in the thread pool
regardless. SharedThreadPool already has some logic for selecting a
reasonable stack size for worker threads; let's move that logic to
nsIThreadManager so that logic (and constant) can be shared more
broadly. (That we already have a couple of instances of
SharedThreadPool usage solely for this constant suggests that it is a
concept that should be available in a more central location.)
The trick here is that we read in the element type before we expand the array, so that we
can write it to the new array before it becomes constified.

Various atom-related things have improved recently.
- The main atom table is now threadsafe (bug 1275755) and so can be accessed on
any thread. It has also been split into pieces (bug 1440824), which greatly
reduces lock contention.
- A cache has been added to the HTML5 parser (bug 1352874) that removes the
need for most of the full table lookups.
As a result, there is no point having a separate static atom table. This patch
removes it.

The intention is a little more clear with static_assert, as well as
failing sooner. (The code is probably the same, since the compiler will
optimize out the checks as dead code, but meh.)
Reading nsIIDs to binary streams requires 1 + 1 + 1 + 8 calls to Read
for the underlying stream. With the assumption that reading to the
underlying stream for a binary stream is relatively expensive, we should
be able to do better by reading the byte array in an nsIID in a single
Read() request. The same logic applies to writing nsIIDs. Performing a
single operation here should not change the actual bytes read or
written. Performing a single operation also has the virtue of
performing fewer error checks and whatnot.
These are C++ files now. This makes it so the highlighting works if
you use classes, etc.
Also, add Vim modelines.
