Deleted a line that makes rocprof abort when using fine grained control one several APIs at a time. The parsing function in libtracer_tool.so that parses the input XML file that specifies the functions for which the user wants to activate the tracing callbacks seems to handle correctly cases where fine-grained control is used on several APIs. This line can be safely deleted.
Isolated flushing instructions into a wrapping function. The file descriptor used for flushing is the one that is globally defined and not the one stored in the context_entry_t object as it is always the one that is defined globally that is used. If using a globally defined file descriptor is problematic (however it is the norm in the libtracer_tool.so library in ROCTracer) rather than passing it through arguments, the wrapping flushing function can be modified to take a void pointer. The file descriptor can then be passed through this pointer and be used in the default flushing function.

The signature of the function that flush metrics has been updated in order to have a standard signature for all the flushing functions. A new data structure that is passed as the only one argument for the function has also been defined
As for the metrics, the kernel flushing function signature has been updated and a new data structure has been defined

This is the third pull request for the proposal for a plugin interface for the rocprof command. In this pull request, the signatures of the flushing functions are standardized for every API/kind of event.
The signatures of all flushing function are now of this kind : void <API>_flush_cb(<API>_trace_entry_t *entry)
Where <API> is the kind of event or API that is traced and <API>_trace_entry_t is a wrapping data structure containing the payloads of the traced events.
Relative to the second pull request, this one starts at commit 65161e2
