This patch builds upon the existing DLL services functionality:
1) We add code to obtain the name of the subject from the cert used to sign a
binary (if present). This code is added inside mozglue because in the future
we will be using this code from the DLL blocklist, which is also located
there.
2) We add annotation functionality that registers itself for DLL load events
and updates crash reporter annotations as new libraries are loaded. It also
annotates any existing libraries that are also in memory at the time that the
CertAnnotator is first instantiated. This all happens off main thread, with
the exception of actually making the annotation when in a child process.

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
libraries, albeit not detecting their bridge (and with the
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.

These flags are only relevant on OS X, and will not be necessary soon, so this
commit moves them to a separate variable while we move the remainder of the
ldflags to mozbuild.

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.

jemalloc_ptr_info() gives info about any pointer, such as whether it's within a
live or free allocation, and if so, info about that allocation. It's useful for
debugging.
moz_malloc_enclosing_size_of() uses jemalloc_ptr_info() to measure the size of
an allocation from an interior pointer. It's useful for memory reporting,
especially for Rust code.

Bug 1186064 removed most of it when we started requiring VS 2015u2, but
the "frex" function exported through mozglue.def.in was only used
through the MSVCRT being patched by fixcrt.py, which is not done anymore.
So the "frex" export is not used anymore, and so the "dumb_free_thunk"
function is not used anymore as well.

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.

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.
This avoids many additions of `extern "C"` in C++ code and will avoid
having to do the same to mozjemalloc once built as C++.

This will prevent the profiler from suspending a target thread while that thread holds the RtlLookupFunctionEntry lock, which the profiler itself also wants to use.
Everything depending on the widget being gonk can go away, as well as
everything depending on MOZ_AUDIO_CHANNEL_MANAGER, which was only
defined on gonk builds under b2g/ (which goes away in bug 1357326).

#include'ing system headers inside anonymous namespaces seems to work
OK with GCC and MSVC, but it does not work well with clang-cl in some
compilation modes. Moving them out of the anonymous namespace makes
everybody happy.

Vorbis.acm seems to be somehow injecting itself into our process, and also the
Flash process, and intercepting the system audio APIs. Version 0.0.3.6 seems to
be crashing, and it's an obsolete version, so we should block it to stop it
crashing us.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

Per froydnj in bug 1186064 comment #23, "it makes sense to proceed with removing
MSVC 2013 support." This commit does that.
We also go a step further and require VS2015 Update 2 instead of just
update 1. This temporarily brings us down to just 1 officially supported
Visual Studio version. However, VS2015u3 was just released and is
unofficially supported.
Since MOZ_CRT is no longer set, references to it have been removed.

Detecting AVX2 requires the use of a sub-leaf.
To make things easier we remove our use of the cpuid.h
implementation on GCC and just use our existing inline asm
implementation.
arm.h still have CPU feature detection for Microsoft Compiler that is used by WinCE. Since we don't have the target for WinCE, we should remove it.
Also, even if you need it for Win32/arm that is Windows Mobile and Windows IOT in feature, this is unnecessary. Win32/arm ABI requires thumb2+NEON at least.
