pfm_initialize - initialize performance monitoring library
This is the first function that a program using the library must call
otherwise the library will not function at all. This function will
probe the host CPU and automatically detect which PMU it has. All
internal data structures will be initialized as a result of this call.
In the case of a multi-threaded application, this function needs to be
called only once, most likely by the initial thread.
The function returns whether or not it was successful, i.e., the host
PMU has been correctly identified and is supported. A return value of
PFMLIB_SUCCESS indicates success, otherwise the value is an error code.
the host PMU is not supported.
