As well as adding MOZ_MUST_USE to a number of functions, this patch:
- Changes the return type of nsObserverList::GetObserverList() from |nsresult|
to |void|, because it always returned NS_OK and none of the callers checked
the result.
- Removes an unnecessary |new| check in nsSupportsArray::Enumerate().

A few callers of NS_NewISupportsArray() didn't use the return value to detect

It looks like VC++ doesn't like comparisons of nsCOMPtr to 0 after this
change, but those are bad style anyway, so I removed them from
TestCOMPtr.cpp instead of trying to make them work.
It's an annotation that is used a lot, and should be used even more, so a

When PluginInstanceChild receives native key events, it should post the events to the chrome process first for checking if the key combination is reserved. However, posting all key events to the chrome process may make damage to the performance of text input. Therefore, this patch starts to post a key event whose key combination may be a shortcut key. However, for avoiding to shuffle the event order, it posts following key events until all posted key events are handled by the chrome process.
For receiving response from widget, this patch defines nsIKeyEventInPluginCallback. It's specified by nsIWidget::OnWindowedPluginKeyEvent() for ensuring the caller will receive the reply. Basically, the caller of nsIWidget::OnWindowedPluginKeyEvent() should reply to the child process. However, if the widget is a PuppetWidget, it cannot return the result synchronously. Therefore, PuppetWidget::OnWindowedPluginKeyEvent() returns NS_SUCCESS_EVENT_HANDLED_ASYNCHRONOUSLY and stores the callback to mKeyEventInPluginCallbacks. Then, TabParent::HandledWindowedPluginKeyEvent() will call PuppetWidget::HandledWindowedPluginKeyEvent().

Outer pointers for object aggregation never get used. Having these
always-null pointers around means extra space to store them and extra
instructions to deal with them. Let's just remove them.
js::Class op are often all null. And when they're not all null, they're often
duplicated among classes. By pulling them out into their own struct, and using a

XPCOMThreadWrapper::GetCurrent() is failing because it's not keeping
AbstractThread::sCurrentThreadTLS up to date. This causes assertion failures
during startup of the GMP stack when dispatching via InvokeAsync to the GMP
thread, which is an XPCOM thread wrapped by the XPCOMThreadWrapper.
We can trivially initialize AbstractThread::sCurrentThreadTLS to be the
XPCOMThreadWrapper on the target thread, since it's thread-local-storage, and

This patch changes things so that dynamic atoms and static atoms have distinct
implementations. This is a step towards allowing dynamic atoms and static atoms
to have different layouts in memory, which will allow static atoms to be
represented more compactly.
Specifically, the patch does the following.
- It renames AtomImpl as DynamicAtom and PermanentAtomImpl as StaticAtom, and
the latter is no longer a subclass of the former. This required duplicating
some methods from the former into the latter: ScriptableToString(),
ToUTF8String(), ScriptableEquals(), IsStaticAtom(). (This duplication will
disappear in the future if the representations of dynamic atoms and static
atoms diverge. Indeed, SizeOfIncludingThis() is already different in the two
classes.)
- It replaces all mentions of "permanent"/"non-permanent" atoms with
"static"/"dynamic".
- In ~DynamicAtom() it removes the check that causes gAtomTable to be deleted
when it becomes empty. This will only happen at shutdown and so doesn't seem
useful.
- It documents better various things, especially the basics of the
dynamic/static split, the transmutation of dynamic atoms to static atoms, and
the details of the SizeOf functions.

Also fixes bug 926980 - load ICU data from an archive file.
Stop invoking ICU's autoconf build system. Instead, have hand-authored
moz.build files under config/external/icu to build what we need. In addition,
we'll commit a pre-built copy of the ICU data file (currently icudt56l.dat)
under config/external/icu/data to avoid having to build ICU host tools to
generate it. config/external/icu/data also contains some assembly files
which can generate an object file containing the ICU data file contents
so that the JS shell (or standalone JS builds) can be linked directly to
the data without having to deal with the external data file. This requires
yasm or GNU as.
Various bits of packaging have been updated to account for the ICU data file.
XPCOM initialization now sets the ICU data directory so ICU can locate its
data file.
The update-icu.sh script has been modified to read the list of C/C++ source
files out of the ICU Makefiles and update `sources.mozbuild` files under
config/external/icu, as well as build a local copy of ICU using its
autoconf build system to generate the ICU data file to be committed in-tree.

We have some oddities in our jemalloc stats reporting.
- "heap-overhead-ratio" is a strange measurement: overhead / non-overhead,
expressed as a percentage. And it omits "bin_unused", which appears to be an
oversight.
- "heap-committed" also omits "bin_unused".
- There are some minor errors in memory report descriptions.
This patch fixes these and improves the heap reporting. It makes the following
reporting changes:
- "heap-allocated": Duplicated as "heap-committed/allocated". (We keep
"heap-allocated" because that's a special value used in the computation of
"heap-unclassified".)
- "heap-committed/overhead": Added; it's the same as the sum of the
"explicit/heap-overhead/*" values. Together with "heap-committed/allocated"
it shows clearly what fraction of the heap is overhead and what fraction is
useful.
- "heap-committed": Removed; now implicit as the "heap-committed/" node.
- "heap-overhead-ratio":
- Removed from memory reports; now shown as the percentage of the new
"heap-committed/overhead" node.
- Still available as a distinguished amount (because it's useful in
isolation) but renamed to heapOverheadFraction, and the telemetry ID is
renamed as MEMORY_HEAP_OVERHEAD_FRACTION.
- "heap-chunks": Removed; it's not that interesting, and can be manually
computed as "heap-mapped" / "heap-chunksize" if necessary.

Part 1: Refactored LoadLibrarySystem32 to expose the system32-path
construction code, so it can be re-used in the following patch.
MozReview-Commit-ID: J5BcI34VPnN
GetSerialNumber accesses global state through gSerialNumbers. We call
GetSerialNumber under a lock when doing normal object refcount logging.
However, we call GetSerialNumber outside of a lock when we're tracing
individual classes for nsCOMPtr refcount logging, even if we don't
actually care about nsCOMPtr refcount logging. We should call it under
a lock always.
UniquePtr is more standard than ScopedFreePtr; using standard constructs
whenever possible is preferable. In this particular case, since we
really just need a chunk of memory, we can allocate a char[] via
MakeUnique.
XPTInterfaceDescriptor::num_additional_types can easily fit in 8 bits -- in
practice it doesn't exceed 20, and there's already a check in DoTypeDescriptor
that it doesn't exceed 255. This patch shrinks it and moves that check into
XPT_InterfaceDescriptorAddTypes() so that any overflow would be detected more
reliably.
On 64-bit platforms this reduces sizeof(XPTInterfaceDescriptor) from 40 to 32
and correspondingly reduces "xpti-working-set" by 16 KiB.
The patch also changes XPT_InterfaceDescriptorAddTypes() into a local function,
because it's defined and only used in xpt_struct.cpp.

XPT has some functions and macros for freeing memory. However, they (a) are

Currently XPT can both encode and decode, but encoding has been handled by
Python code since bug 643817, so the encoding support can be removed. This
results in many simplifications. Some notable changes:
- All the XPTHashTable code (including XPTDatapool::offset_map) is no longer
necessary.
- PrimitiveTest.cpp and SimpleTypeLib.cpp both don't make much sense without
encoding support, so I removed them.
- A lot of the version code was already unused, e.g. XPT_VERSION_*,
XPT_TYPELIB_VERSIONS_STRUCT, XPT_TYPELIB_VERSIONS.
XPT_MAJOR_INCOMPATIBLE_VERSION is the only thing actually used in version
checks.
- The patch also removes some code that was dead even before encoding removal,

StringBeginsWith (resp. StringEndsWith) takes a defaulted
nsStringComparator object for doing comparisons. The flexibility this
affords is great, but the cost is not: nsStringComparator has virtual
methods, so initializing that defaulted object (at every callsite)
requires a temporary object whose vtable must be initialized.
Since the overwhemingly common case is to use the default comparator
anyway, we should not use defaulted arguments and instead provide the
default comparator/user-provided comparator cases as separate overloads.
This change eliminates the virtual call for the majority of callsites
and reduces codesize as well.
