run-tests: mechanism to report exceptions during test execution

Sometimes when running tests you introduce a ton of exceptions.
The most extreme example of this is running Mercurial with Python 3,
which currently spews thousands of exceptions when running the test
harness.

This commit adds an opt-in feature to run-tests.py to aggregate
exceptions encountered by `hg` when running tests.

When --exceptions is used, the test harness enables the
"logexceptions" extension in the test environment. This extension
wraps the Mercurial function to handle exceptions and writes
information about the exception to a random filename in a directory
defined by the test harness via an environment variable. At the
end of the test harness, these files are parsed, aggregated, and
a list of all unique Mercurial frames triggering exceptions is
printed in order of frequency.

This feature is intended to aid Python 3 development. I've only
really tested it on Python 3. There is no shortage of improvements
that could be made. e.g. we could write a separate file containing
the exception report - maybe even an HTML report. We also don't
capture which tests demonstrate the exceptions, so there's no turnkey
way to test whether a code change made an exception disappear.
Perfect is the enemy of good. I think the current patch is useful
enough to land. Whoever uses it can send patches to imprve its
usefulness.

# All revsets ever used with revsetbenchmarks.py script
#
# The goal of this file is to gather all revsets ever used for benchmarking
# revset's performance. It should be used to gather revsets that test a
# specific usecase or a specific implementation of revset predicates.
# If you are working on the smartset implementation itself, check
# 'base-revsets.txt'.
#
# Please update this file with any revsets you use for benchmarking a change so
# that future contributors can easily find and retest it when doing further
# modification. Feel free to highlight interesting variants if needed.


## Revset from this section are all extracted from changelog when this file was
# created. Feel free to dig and improve documentation.
