support for stats static userspace probes via systemtap
We currently only have probes for the logging sub-system.
This patch adds two tracepoints for tracing the performance
impact of statistics reporting: stat_start and stat_done.
They can be used to trace the amount of time a libosmocore-using
application spends in reporting/exporting statistics. This includes
both the CPU time for encoding the statistics, as well as the system
calls for sending them.
