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,
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.

Use the UI thread's tid for checking if we're on the UI thread in Gecko.
This lets us get rid of `GeckoThread.registerUiThread`, in order to
avoid a race where we check for UI thread before `registerUiThread` is
called.

Just one caller (in DMD) actually looks at it, and that's in an unimportant way
-- if the return value was false, mLength would be zero anyway.

This patch does he following.
- Avoids some unnecessary casting.
- Renames the |bp| parameter as |aBp|.
- Makes the no-op FramePointerStackWalk() signature match the real one.
(Clearly it's dead code in all built configurations!)

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.
