Message

Event probe (eprobe) is a new type of ftrace dynamic events, introduced
in the Linux kernel 5.15 version. It is useful to have support for them
in trace-cruncher, as it allows more flexibility when printing event's
data.

v2 changes:
 - Moved unit test in a separate patch.
 - Added a check in the unit test if the kernel supports eprobes.
 - Renamed the API from PyFtrace_register_eprobe() to PyFtrace_eprobe(), for
   consistency with the other dynamic events APIs.
