[Bug translator/5898] New: adapt stap -c for user probes

["jkenisto at us dot ibm dot com" <sourceware-bugzilla at sourceware dot org>]

stap should support some kind of probe syntax that means essentially
  probe process(target()).function("func") etc.
so when the user says
  stap -c pgm xxx.stp
and xxx.stp contains a probe definition like the above, the stap-generated
module registers the probe using pgm's pid, after the staprun child execs pgm.

Kprobes are registered before the exec, but uprobes registration must wait 'til
the process is running the right program.  I guess this means registering a
utrace  engine, with exec callback, during systemtap_module_init() and having
the exec callback register the uprobes.
