automation: make system3 the default for run-tests-linux
We'll soon drop support for Python 2.7. Let's use Python 3 by
default.

perf extension - helper extension to measure performance
Configurations
==============
"perf"
------
"all-timing"
When set, additional statistics will be reported for each benchmark: best,
worst, median average. If not set only the best timing is reported
(default: off).
"presleep"
number of second to wait before any group of runs (default: 1)
"pre-run"
number of run to perform before starting measurement.
"profile-benchmark"
Enable profiling for the benchmarked section. (The first iteration is
benchmarked)
"run-limits"
Control the number of runs each benchmark will perform. The option value
should be a list of '<time>-<numberofrun>' pairs. After each run the
conditions are considered in order with the following logic:
If benchmark has been running for <time> seconds, and we have performed
<numberofrun> iterations, stop the benchmark,
The default value is: '3.0-100, 10.0-3'
"stub"
When set, benchmarks will only be run once, useful for testing (default:
off)

Test run control
----------------
Simple single entry
$ hg perfparents --config perf.stub=no --config perf.run-limits='0.000000001-15'
! wall * comb * user * sys * (best of 15) (glob)
Multiple entries
$ hg perfparents --config perf.stub=no --config perf.run-limits='500000-1, 0.000000001-5'
! wall * comb * user * sys * (best of 5) (glob)
