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.

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.

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,

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.

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.

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

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.

For pthreads platforms, we have a terribly large condition for the size

pthread_mutex_t takes. This hardcoding isn't always correct. We
originally did this to try and keep <pthread.h> includes out of the
headers, but the PlatformConditionVariable.h header already includes
<pthread.h> anyway, and <pthread.h> isn't so namespace-invasive as
<windows.h>. So go ahead and include <pthread.h> and use the actual
definition of pthread_mutex_t to size the platformData_ member.
