Remove thread_data_init. The C++ standard guarantees that the thread
local variable is initialized before its first odr-use and destructed
when the thread exits. Use a global initializer to set the reference
from the message stack instance in the map.
Remove roctracer_error_string. This does not belong to this library.
ROCTX does not expose errors to the application. The only functions
returning errors are returning -1 (Push/Pop).
Remove memory leaks due to strdup on the ranges messages. The memory
for the messages is guaranteed to be valid for the duration of the
callback, and it is the application's responsibility to strdup the
strings if it needs to extend the message's lifetime.
Add a lock to the RegisterApiCallback implementation. Iterating the
message stack map must be synchronized as a new thread could be adding
a new value to the map.
