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.

This assertion was always meant to be a best-effort thing to catch obvious
errors, but the cases where the assumptions it makes fail have been growing. I
could remove it entirely, but I'd be happier keeping at least some basic
sanity checks.
This compromise continues allowing any address below the first argument
pointer, and extends the assertion to also allow anything more than 2KiB above
it. We could probably get away with stretching that to at least 4KiB, but 2
seems safer, and likely enough to catch the obvious cases.

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.

The sStaticModules list is, practically speaking, a copy of the list
of components we already have in libxul, augmented at runtime with
a few other components for tests (for gtest and xpcshell). We don't
actually need to keep that copy in memory. We can instead just use the
pointers in libxul directly to register them to the component manager,
and use a separate list, only for those extra components when they need
to be registered.

Unfortunately, I wasn't able to figure out a way to make firefox build & run in
the intermediate stages of these commits. Because of this, I am going to just
delete most of the code which I am deleting in the first patch, as I figure that
those are somewhat uninteresting changes, and then make the other changes in the
following patches.
In total, the following things are deleted:
1. All of xpcom/typelib, except for `xpt/tools` - this directory is being
subsumed entirely into xpcom/reflect/xptinfo.
2. Most of the code in xpcom/reflect/xptinfo, it is being rewritten to avoid
allocating and contain all of the necessary data structures.
3. idl-parser's typelib.py XPT generator, as it will be replaced.
4. Most includes of files which have been deleted.
NOTE: xpcom/typelib/xpt/tools/xpt.py was not removed, as it is used by bundling
code & bundling tests, which we don't want to remove yet.
This patch removes C++ code related to reading in XPT information from
files. (Code related to packaging XPT files will be removed in the
next patch.) This includes code in the manifest parser, in addition to
the actual code for parsing files.
XPT information is now loaded directly from a single static data
structure, XPTHeader::kHeader, which will be automatically generated
at compile time from .idl files (via .xpt files). Note that the script
to do that is not added until part 6 of this patch series, so linking
will fail on parts 2 through 5.
I inlined XPTInterfaceInfoManager::RegisterXPTHeader into the ctor,
because that is the only caller. It feels like the lock there should
not be needed any more, but I left it alone for now.
The forward declaration of XPTArena in xptiprivate.h is needed because
it was being bootlegged via xpt_xdr.h. Some of the data structures in
reflect/xptinfo/ (which wrap the xpt_struct.h data structures) are
still allocated using XPTArena. Hopefully we can get rid of that in
followup work.
I also deleted a lot of comments in xpt_struct.h that talk about the
on-disk format. I also deleted checking of the major version number,
because that should not matter when the XPT information is baked into
the executable.

Right now, NS_GENERIC_FACTORY_SINGLETON_CONSTRUCTOR expects singleton
constructors to return already-addrefed raw pointers, and while it accepts
constructors that return already_AddRefed, most existing don't do so.
Meanwhile, the convention elsewhere is that a raw pointer return value is
owned by the callee, and that the caller needs to addref it if it wants to
keep its own reference to it.
The difference in convention makes it easy to leak (I've definitely caused
more than one shutdown leak this way), so it would be better if we required
the singleton getters to return an explicit already_AddRefed, which would
behave the same for all callers.
This also cleans up several singleton constructors that left a dangling
pointer to their singletons when their initialization methods failed, when
they released their references without clearing their global raw pointers.

This is straightforward, with only two notable things.
- `#include "nsXPIDLString.h" is replaced with `#include "nsString.h"`
throughout, because all nsXPIDLString.h did was include nsString.h. The
exception is for files which already include nsString.h, in which case the
patch just removes the nsXPIDLString.h inclusion.
- The patch removes the |xpidl_string| gtest, but improves the |voided| test to
cover some of its ground, e.g. testing Adopt(nullptr).

Manifest entries can contain flags, one of which allows to match on the
os running Gecko. The match is performed against the value returned by
nsIXULRuntime.getOS, which itself comes from the build-system's
OS_TARGET.
In practice, this means that things like os=WINNT, os=Darwin,
os=Android, os=Linux are valid filters, but the latter is too specific,
and most of the time, one would want something that is "any OS but
WINNT, Darwin, Android", which can't be expressed with manifest entry
flags (there is no "and" for them, only "or").
For convenience, we add the keyword "LikeUnix", which has that meaning.

This is a patch from 2016/04/27 16:36:50 ryoon found on
http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/www/firefox45/patches/#dirlist.
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.

Having the Impl suffix isn't really necessary, and if we start creating
instances of these classes directly, it's also rather ugly. Let's get

The patch changes all uses of SizeOfIncludingThisMustBeUnshared() to
SizeOfIncludingThisIfUnshared(). This incurs the (tiny) cost of an unnecessary
IsReadonly() check for guaranteed-unshared strings, but avoids the possible
assertion failures that would occur when MustBeUnshared() was used incorrectly

This is similar to the solution adopted for bug 1190985, a race in
netwerk's DebugMutexAutoLock. A relaxed atomic tells tools like TSan
that we're OK with this variable being touched from multiple threads.
That it's only set from within a locked mutex should ensure whatever
memory barriers we need are executed so all threads have a consistent
view of what value it contains.
Getting rid of another |volatile| usage in the codebase is just a bonus.
