b0d67064b5 Check for null FILE handles in ReportTopology 
On Linux `/sys` is not guaranteed to exist. When it doesn't, tracy
would crash with a SIGSEGV due to a nullptr dereference. Not actually
sure how well tracy clients will handle the case where this information
is missing, though.

29886435b4 ___tracy_alloc_* take pointer-size pairs 
This enables better bindings in languages that do not have 0-terminated
strings for source/function name. It does not introduce any additional
overhead in languages that do use 0-terminated strings, either, but it
_is_ a breaking API change.

Fixes https://github.com/wolfpld/tracy/issues/53

a110b42011 Add ___tracy_init_thread function 
This function needs to be called for each non-main thread before calling
the `___tracy_alloc_` functions.

Alternative way to achieve this could be initializing the allocator
transparently in the `___tracy_alloc_*` calls.

c2c234cf5a Fix crash when running Tracy from DLLs 
Instantiating Tracy from within a DLL will tie its internal threads life-time to the DLL. Windows does not guarantee
that threads will be alive after the main function. This has implications in the Profiler dtor since will try to perform
some deallocations, however, _memory_deallocate_large will try to get the heap of the current thread which can
be invalid at the point of shutdown causing a crash. Checking the pointer here will won't make TRACE_NO_EXIT
work, but it will prevent the Profiler from crashing.

707117c04f Build sanitization & Static analysis warning fixes 
- Wrapping FORCEINLINE & WIN32_LEAN_AND_MEAN definess with ifndef bc other libraries may define it and trigger redefinition warning
- Possibly contentious given tone in the manual (:P) but removing variable shadowing in TracySysTrace.cpp
  - Alternate Solution: Add #define TRACY_FORCE_SILENT_WARNINGS toggle-able flag. If flag is enabled, push/pop warning disables that have to be included in client code

It is common to receive duplicate stack traces for the same timestamp

containing only kernel frames. Discard the second one, as there's no
documentation how this should be interpreted and the kernel stack is
mostly useless.

25082b2bec Don't report CPU topology if delayed init is active. 
Reporting topology requires producer to be available, which creates a
deadlock during delayed init data structures construction.

Calling GetProducer() results in a call to GetProfilerThreadData(),
which in turn calls GetProfilerData() to construct its thread local
variable. However, at this point we already are calling
GetProfilerData() (to construct the profiler itself). This would result
in an incorrect double construction of data, but the code already
prevents this by allowing init code to be entered only once. Hence the
deadlock.

Currently this is a non-issue, as no platform which can report CPU
topology needs to use delayed init.

c774534b47 Use rdtsc instead of rdtscp. 
But rdtscp is serializing!

No, it's not. Quoting the Intel Instruction Set Reference:

"The RDTSCP instruction is not a serializing instruction, but it does
wait until all previous instructions have executed and all previous
loads are globally visible. But it does not wait for previous stores to
be globally visible, and subsequent instructions may begin execution
before the read operation is performed.",

"The RDTSC instruction is not a serializing instruction. It does not
necessarily wait until all previous instructions have been executed
before reading the counter. Similarly, subsequent instructions may begin
execution before the read operation is performed."

So, the difference is in waiting for prior instructions to finish
executing. Notice that even in the rdtscp case, execution of the
following instructions may commence before time measurement is finished
and data stores may be still pending.

But, you may say, Intel in its "How to Benchmark Code Execution Times"
document shows that using rdtscp is superior to rdstc. Well, not
exactly. What they do show is that when a *single function* is
considered, there are ways to measure its execution time with little to
no error.

This is not what Tracy is doing.

In our case there is no way to determine absolute "this is before" and
"this is after" points of a zone, as we probably already are inside
another zone.  Stopping the CPU execution, so that a deeply nested zone
may be measured with great precision, will skew the measurements of all
parent zones.

And this is not what we want to measure, anyway. We are not interested
in how a *single function* behaves, but how a *whole program* behaves.
The out-of-order CPU behavior may influence the measurements? Good! We
are interested in that. We want to see *how* the code is really
executed. How is *stopping* the CPU to make a timer read an appropriate
thing to do, when we want to see how a program is performing?

At least that's the theory.

And besides all that, the profiling overhead is now reduced.
