Back when the class was written, for the packaging code, it made sense
that the default was True. But now that it's used all over the place,
and that the vast majority of uses are with find_executables=False, it
makes more sense for that to be the default.

The patch also moves some Sampler methods from platform.cpp to Sampler.cpp. Now
all Sampler methods are in Sampler.cpp except for a small number of
platform-specific ones, which are in platform-*.cpp.

There's no point having them as separate classes. This removes the need for
some virtual functions, too.

They're defined separately for each platform, but the definitions are almost
identical and can be commoned up.

It's a clumsy cross-platform abstraction. GetCurrentId() and tid_t are the only
genuinely cross-platform things in it, and the patch keeps those in place.
The remaining methods are not implemented on all platforms (none are
implemented on Linux) and the fields are all used on either Mac or Windows, but
not both. So the patch moves the relevant Thread method implementations and
fields into the existing SamplerThread classes. There is sufficiently little
overlap between the two SamplerThread classes that there is no point sharing a
base class between them. This avoids the need for virtual functions, and
simplifies thread naming on Mac.
The patch also changes some of the existing code to use Gecko style, e.g.
|mFoo| instead of |foo_| for class fields.
This variable is set in GeckoSampler's destructor and cleared in GeckoSampler's
destructor, which means it's just another handle to the GeckoSampler singleton,
which means it duplicates gSampler.
This patch replaces its uses with gSampler uses. This exposes various places
where GeckoSampler is being accessed off the main thread, which I have marked
with XXX comments.

There is a single GeckoSampler and it is currently only accessed on the main
thread, so it's silly to use TLS for it; a normal global variable is better.
This patch also adds main thread assertions to a number of the profiler_*()
functions. Even though bug 1330184 may get rid of some of them, right now they
are a useful as both a sanity check and documentation.

Note that the comment on ::Mutex said that it should support recursive locking,
but GeckoMutex was implemented using mozilla::Mutex which does *not* support
recursive locking.
The patch also removes OS::CreateMutex(), because it's only used twice and
doesn't make the code more concise.

There are lots of profiler_*() functions that simply call onto equivalent or
nearly-equivalent mozilla_sampler_*() functions. This patch removes the
unnecessary indirection by removing the mozilla_sampler_*() functions.
The most important changes:
- In platform.cpp, all the mozilla_sampler_*() definitions are renamed as
profiler_*().
- In GeckoProfiler.h, the new PROFILER_FUNC{,_VOID} macros provide a neat way
to declare the functions that must be present whether the profiler is enabled
or not.
- In GeckoProfiler.h, all the mozilla_sampler_*() declarations are removed, as
are all the profiler_*() definitions that corresponded to a
mozilla_sampler_*() function.
Other things of note:
- profiler_log(const char* str) is now defined in platform.cpp, instead of in
GeckoProfiler.h, for consistency with all the other profiler_*() functions.
Likewise with profiler_js_operation_callback() and
profiler_in_privacy_mode().
- ProfilerBacktraceDestructor::operator() is treated slightly different to all
the profiler_*() functions.
- Both variants of profiler_tracing() got some early-return conditions moved
into them from GeckoProfiler.h.
- There were some cases where the profiler_*() and mozilla_sampler_*() name
didn't quite match. Specifically:
* mozilla_sampler_get_profile_data() and profiler_get_profiler_jsobject():
name mismatch. Kept the latter.
* mozilla_sampler_get_profile_data_async() and
profiler_get_profile_jsobject_async(): name mismatch. Kept the latter.
* mozilla_sampler_register_thread() and profiler_register_thread(): return
type mismatch. Changed to void.
* mozilla_sampler_frame_number() and profiler_set_frame_number(): name
mismatch. Kept the latter.
* mozilla_sampler_save_profile_to_file() and
profile_sampler_save_profile_to_file(): the former was 'extern "C"' so it
could be called from a debugger easily. The latter now is 'extern "C"'.
- profiler_get_buffer_info() didn't fit the patterns handled by
PROFILER_FUNC{,VOID}, so the patch makes it call onto the new function
profiler_get_buffer_info_helper(), which does fit the pattern.

Now that XRE_LibFuzzerGetFuncs is not used from outside libxul, it can
be inlined in LibFuzzerRunner::Run, simplifying things a little more.

Going further from the previous changes, all libfuzzer_main really does
is call the init function, and then proceed to call the fuzzer driver
with the testing function.
So instead of calling that function for it to do all that, the
LibFuzzerRunner can just call the init function itself, and then
call the fuzzer driver with the testing function.

The LibFuzzerRunner code lives in libxul. It's unnecessary complications
to have it call back a function in the firefox executable just so that
it calls another function that is in libxul. Passing the init and
testing functions to the libfuzzer_main function allows to just bypass
that roundtrip, simplifying the setup.
