Change thread id size from 64 to 32 bits. 
Both Windows and Linux use 32-bit thread identifiers. MacOS has a 64-bit
counter, but in practice it will never overflow during profiling and no false
aliasing will happen.

These changes are only done client-side and in the network protocol. The
server still uses 64-bit thread identifiers, to enable virtual threads, etc.

Don't init rpmalloc, if we know it has been done already. 2021-06-10 01:48:11 +02:00

Check if rpmalloc has to be initialized before each operation. 
The C++11 spec states in [basic.stc.thread] thread storage duration:

2. A variable with thread storage duration shall be initialized before its
   first odr-use (3.2) and, if constructed, shall be destroyed on thread exit.

Previously Tracy relied on the TLS data being initialized:
- During thread creation (MSVC).
- Or during first use in a thread, but the initialization was performed for
  the whole TLS block.

It seems that new compilers are more granular with how they perform the
initialization, hence rpmalloc init has to be checked before each allocation,
as it cannot be "folded" into, for example, initialization of the profiler
itself.

0d2e7f72a7 Move GetThreadHandleImpl() from header to source file. 
This removes dependency on unistd.h header (required for syscall() on
linux), which includes a definition of getopt(), which may conflict with
a custom getopt implementation (for example, one that does work on
windows).

92b6da7cc2 SetThreadName() only works on the current thread. 
This breaking change is required, because kernel trace facilities use
kernel thread ids, which are inaccessible from the pthread_t level.

813e265bc3 Initialize rpmalloc in SetThreadName(). 
There's no guarantee that rpmalloc will be initialized when the thread
calls SetThreadName, due to thread_local storage initialization rules.
