perf: make sure to explicitly disable any profiler after the first iteration
The current code work, because of some edge behavior of the `profile` class. We
make it explicit that the profiler is not in effect more than once.

match: remove an obsolete comment about util.finddirs()
Obsolete since
8e55c0c642c (util: make util.dirs() and util.finddirs()
include root directory (API), 2017-05-16).

match: de-flake test-doctest.py by not depending on util.dirs() order
util.dirs() yields directories in arbitrary order, which has made
test-doctest.py flaky. I think they have been flaky since
d8e55c0c642c
(util: make util.dirs() and util.finddirs() include root directory
(API), 2017-05-16). Before that commit, I think util.dirs() would
return at most one entry, so there was only one iteration order. This
patch fixes the problem by making _rootsdirsandparents() return a set
(whose __str__() is defined to be in sorted order, I believe). The
only caller wanted a set anyway.

perf: add an option to profile the benchmark section
Running a perf command with --profile gather data for the whole command
execution, including setup and cleanup. This can significantly alter the data.
To work around this we introduce a new option, it trigger the profiling of only one
iteration of the benchmarked section.
perf: add a `pre-run` option
sometimes, the initial run is necessary to warm some cache that are not relevant
for the current measurement. We add a new `perf.pre-run` option to specify a
number of run of the benchmark logic that will happens before measurement are
taken.
narrow: consider empty commits to be "inside the narrow spec" for templates
It doesn't seem useful to exclude them, or harmful to include them. Users
writing log templates using outsidenarrow as a predicate might consider it
unexpected if their locally created empty drafts are treated as if they
contained something outside the clone.

rust-python3: useless python2 specific import
This python27_sys import prevents building with python3,
it had been previously removed in

has been since pruned
