The overlapping process.* tapsets are now separated. Those probe points
documented in stapprobes(3stap) remain the same. Those that were formerly
in stapprobes.process(3stap) have been renamed to kprocess, to reflect
their kernel perspective on processes.

Much of this was contributed by Manoj Pattabhiraman (IBM).

* examples/small_demos/proc_snoop.stp,
testsuite/buildok/process_test.stp: Rename process.signal_* to
new signal.* tapset.

* process.stp (exec, exec_complete): conditionally include
compat_do_execve for 64-bit kernels

* process.stp: Rename signal.send to signal_send and process.complete
to process_complete, to allow process.* to work properly.
* process.stp (_IS_ERR): declare parameter type
* process.stp (process.create): correct new_pid assignment

I checked into CVS those generic tapsets at the first step.

|
* task.stp: functions to retrieve task information
