revsetbenchmark: add a summary at the end of execution The summary list timing per revset making it much more easier to compare revision to each other.

revsetbenchmark: retrieve the benchmark value in python We retrieve the output of the perf extension and print it ourself. This open the door to processing of this data in the script.

revsetbenchmark: get revision to benchmark in a function And move it to proper subprocess call.

revsetbenchmark: convert revision display to proper subprocesscall

revsetbenchmark: convert performance call to proper subprocess call

revsetbenchmark: convert update to proper subprocess call

revsetbenchmark: fix semicolon

revsetbenchmark: simplify and convert the script to python The script is now in python. That translation is very raw, more improvement to comes: The "current code" and "base" entry have been dropped. This is trivial to get same result using a tagged revision or "." in the list of benchmarked revision.

revsetbenchmapi: fix template The revision description missed an \n

perf: unroll the result in perfrevset With the new lazy revset implementation, we need to actually read all elements to trigger all the computations. Otherwise a no-op if of course much faster than the full work.
