run-tests: report tests that exception occurred in

We now record the test that an exception occurred in. We put this
information to use by aggregating the count of failures in each
test. For each exception, the exception report now prints the total
number of tests having that exception and the test with the least
number of exceptions exhibiting that failure. The exception list
is now sorted by (total count, tests impacted, count of failures
in least failing test).

This allows us to:

* Assess how widespread a failure is. Some exceptions occur a lot
  in a few tests. Others occur over many tests.
* Easily run a test exhibiting an exception without having to find
  a failure in test output.
* Find and fix low hanging fruit (e.g. exceptions that are the
  only failure in a test).

Here's an example of the new output:

199 (4 tests)   /home/gps/src/hg/hgext/blackbox.py:191: %b requires a bytes-like object, or an object that implements __bytes__, not 'str' (test-devel-warnings.t - 1 total)

====================================
Testing head checking code: Case A-2
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category A: simple case involving a branch being superceeded by another.
TestCase 2: multi-changeset branch

.. old-state:
..
.. * 1 branch with 2 changesets
..
.. new-state:
..
.. * another 2-changeset branch succeeding the old one
..
.. expected-result:
..
.. * push allowed
