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.

The linker uses zlib. The linker is in mozglue, zlib is in libxul by
default. As a consequence, we made --with-system-zlib a requirement for
builds enabling the linker.
In the meanwhile, we added an option that makes zlib built in mozglue
for different needs, which, in fact, also allows to do that when the
linker is enabled.
So, allow to build without system zlib when the linker is enabled.

Since bug 1307886, we don't actually use szip anymore, and don't even
have the option to package Fennec using it. We can thus remove the
support for loading them, as well as on demand linkage.
The latter might mean we can remove the segfault handler, but it's
unclear whether this is currently working around other issues with
registering signal handlers, so we'll leave that to a followup.

CRITICAL_SECTIONs have useful debug info that we'd like to keep around at least
on nightly, rather than having diverging signatures on crash stats we'd like to
just keep a unified implementation. As we didn't see significant perf
improvements after landing we're going to just back this out.
This patch reduces the differences between builds where the profiler is enabled
and those where the profiler is disabled. It does this by removing numerous
MOZ_GECKO_PROFILER checks.
These changes have the following consequences.
- Various functions and classes are now defined in all builds, and so can be
used unconditionally: profiler_add_marker(), profiler_set_js_context(),
profiler_clear_js_context(), profiler_get_pseudo_stack(), AutoProfilerLabel.
(They are effectively no-ops in non-profiler builds, of course.)
- The no-op versions of PROFILER_* are now gone. The remaining versions are
almost no-ops when the profiler isn't built.

EnsureWalkThreadReady takes two locks, one in _beginthreadex and another in the DLL hook setup.
We can avoid the first by not calling EnsureWalkThreadReady if we're walking a suspended thread, since we won't be using a separate WalkThread anyway.
To avoid the hook locks, I gave in and decided to go back to setting up the hooks in DllBlocklist_Initialize as originally planned.
Profiler labels can't currently be used in mozglue, because the profiler's code
is in libxul, and mozglue cannot depend on libxul.
This patch addresses this by basically duplicating AutoProfilerLabel in
mozglue. libxul passes two callback functions to mozglue to do the actual
pushing/popping of labels.
It's an annoying amount of machinery, but it is unavoidable if we want to use
profiler labels within mozglue.

In TSF mode, application should retrieve messages with ITfMessagePump::GetMessage() or ITfMessagePump::PeekMessage() since TSF/TIP may handle the message before or after the host application handles it.
This patch rewrites the API users with WinUtils::(Get|Peek)Message() which use ITfMessagePump if it's available.

Fill in AArch64 trampoline for Divert(). Even though we're not using

This avoids many additions of `extern "C"` in C++ code and will avoid

Add unit tests for Printf. Code coverage now at 90%. Doing better is
difficult due to the large number of assertions and failure cases, and
because some remaining untested code implements behavior undefined by
the spec, for example "%0s".

This annotates vsprintf-like functions with MOZ_FORMAT_PRINTF. This may
provide some minimal checking of such calls (the GCC docs say that it
checks for the string for "consistency"); but in any case shouldn't
hurt.
