Adding or removing an FD from this API currently requires changes in about a
half dozen places. Ignoring the Java side of things. This patch changes the
API to pass a struct, rather than additional arguments for each FD, so that
adding and removing FDs only requires changing one declaration, and the two
call sites that add and consume the FDs.

For clang-cl, we want to add code to libxul that only exists during the
PGO generation phase, so we can collect data. The most expedient way to
do that is to enable certain files in SOURCES to be marked as to only be
compiled during the PGO generation step.
In addition to updating the interface, this patch also significantly alters the
structure of this test. In particular, it removes the Test* functions in favour
of using template magic.
I did this because I noticed that, in the majority of cases, the stub function
was being called with all zero arguments, and then we check for the expected
error code. I thought that maybe we could replace that repetition with some
templates that instantiate a blank tuple that may then be applied to a callable
object.
See the (MAYBE_)TEST_HOOK* and TEST_DETOUR* macro definitions for detailed
information about how to use these things.
The test successfully completes with both 32-bit and 64-bit builds.
This patch makes the interceptor's AddHook functions private, and converts
the stubs from simple function pointers into objects containing both the stub
function pointer, plus a INIT_ONCE sentinel.
Setting a hook now requires calling Set or SetDetour on the stub, which ensures
that the hook attempt happens once and only once.
The constructor for the new object is constexpr, so it should not generate
static initializers if it is declared statically.
Note that, as a corollary of the new behaviour, we no longer need to set guards
around any hook setting code. I have removed those when present.

When we modify the debug map, we could be racing with the system linker,
either when we modify the entries or when we change page protection
flags. To fix the race, we need to take the system linker's internal
lock when we perform any kind of modification on the debug map.
One way to hold the system linker lock is to call dl_iterate_phdr, and
perform our actions inside the callback, which is invoked with the
lock being held. However, dl_iterate_phdr is only present on Android
5.0+, and even then, dl_iterate_phdr is only protected by the linker
lock on Android 6.0+.
This means that with this patch, we can only safely modify the debug map
on Android 6.0+, which I think is acceptable for an operation that only
benefits a debugger.

GetThreadContext() returns a context pointing to its own frame when it

In the past, we also used a walker thread when nullptr is passed in for

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.)

When looping through the debugger helper links during our
dl_iterate_phdr implementation, we effectively race with other threads
dlclose()ing libraries while we're working.
We do have a (rather involved) check in place to ensure that elf headers
are readable. But it turns out in practice, some dlclose() do happen
between the check and the actual read of the elf headers.
Unfortunately, we can't lock the system linker while we're looping, so a
better approach is to only loop through the libraries we loaded, and
rely on the system dl_iterate_phdr to iterate over the (remaining)
system libraries.
Unfortunately (again), Android versions < 5.0 don't have a system
dl_iterate_phdr, so we have to rely on the old iterator when it's not
present.

Because one entry point is simpler than two, we make replace_init fulfil
both the roles of replace_init and replace_get_bridge.
Note this should be binary compatible with older replace-malloc

previous change, they do not register anyways). So loading older
replace-malloc libraries should do nothing, but not crash in awful ways.

The allocator API is a moving target, and every time we change it, the
surface for replace-malloc libraries grows. This causes some build
system problems, because of the tricks in replace_malloc.mk, which
require the full list of symbols.
Considering the above and the goal of moving some of the replace-malloc
libraries into mozglue, it becomes simpler to reduce the replace-malloc
exposure to the initialization functions.
So instead of the allocator poking into replace-malloc libraries for all
the functions, we expect their replace_init function to alter the table
of allocator functions it's passed to register its own functions.
This means replace-malloc implementations now need to copy the original
table, which is not a bad thing, as it allows function calls with one
level of indirection less. It also replace_init functions to not
actually register the replace-malloc functions in some cases, which will
be useful when linking some replace-malloc libraries into mozglue.
Note this is binary compatible with previously built replace-malloc
libraries, but because those libraries wouldn't update the function
table, they would stay disabled.

We already dealt with issues around dlsym not resolving weak symbols
with libc in bug 1081034. This fix applies the same workaround to libm,
which solves the isnanf issue.
The previous fix for looking up __isnanf is no longer needed.
The comment with the accompanying change explains things, but the short
version is that clang generates full calls to isnanf, which our
dlsym-based symbol lookup in the custom linker cannot handle correctly.
We therefore need to do extra work for isnanf to find the correct symbol.
It seemingly hasn't been needed since Mac OS 10.7. A diagnostic assertion that
has been in place for a while hasn't caught any uses of it.

As long as symbols have the right declspec, the linker is going to
export them as expected. The main exception to when we actually need the
exported symbol to have a different name, which is the case for the
symbols normally exported by the CRT. So keep only those renamed symbols
in mozglue.def.in.
Keeping the jemalloc symbols in this file kind of implies that we need
every new API entry points to appear in there when it's not true. This
thus removes an unnecessary moving part when adding new allocator API
entry points.

For obscure linkage reasons, we need all the replace-malloc symbols
being passed to the linker to tell it to allow them being undefined.
That list actually duplicates what's in malloc_decls.h somehow, and
every time we add an entry point, we end up having to modify those two
files (and others, addressed in different bugs), which is suboptimal.
So we generate the list of those symbols from malloc_decls.h.

MozStackWalk() is different on Windows to the other platforms. It has two extra
arguments, which can be used to walk the stack of a different thread.
This patch makes those differences clearer. Instead of having a single function
and forbidding those two arguments on non-Windows, it removes those arguments
from MozStackWalk, and splits off MozStackWalkThread() which retains them. This
also allows those arguments to have more appropriate types (HANDLE instead of
uintptr_t; CONTEXT* instead of than void*) and names (aContext instead of
aPlatformData).
The patch also removes unnecessary reinterpret_casts for the aClosure argument
at a couple of MozStackWalk() callsites.

It appears to be unused, but it would be good to have some real-world data to
confirm this. A diagnostic assertion is a better choice for this than a
telemetry problem because stack-walking is such a low-level operation.

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

It's just a complex wrapper for free(), or equivalent function. (In practice,
all the uses end up in free().)

For some reason the remote decoder process will crash on some x86/Android M devices when SIGSEGV is handled by SIG_DFL. To avoid this issue and continue suppressing crash dialog, capture the signals with Android like handlers and strip debuggerd related code.

MOZ_REPLACE_MALLOC_LINKAGE was added back when there were problems with
getting weak references working properly for replace-malloc.
Versions of OSX < 10.6 needed flat namespace, but aren't supported
anymore.
Versions of Xcode < 4.5 required flat namespace + a dummy library in
order to produce proper weak references. There is virtually nobody still
building with such an ancient toolchain.
Keeping those around doesn't /really/ hurt, except recent versions of
Xcode don't expose dyldinfo in /usr/bin, used for the configure test.
Consequently, MOZ_REPLACE_MALLOC_LINKAGE ended up being set to use the
dummy library setup, which, by using flat namespace, now causes harm in
bug 1356701, causing bug 1378332.

It's silly to use prmem.h within Firefox code given that in our configuration
its functions are just wrappers for malloc() et al. (Indeed, in some places we
mix PR_Malloc() with free(), or malloc() with PR_Free().)
This patch removes all uses, except for the places where we need to use
PR_Free() to free something allocated by another NSPR function; in those cases
I've added a comment explaining which function did the allocation.
