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)

Committing only one hunk while aborting edition of hunk

- Untoggle all the hunks, go down to the second file
- unfold it
- go down to second hunk (1 for the first hunk, 1 for the first hunkline, 1 for the second hunk, 1 for the second hunklike)
- toggle the second hunk
- toggle on and off the amend mode (to check that it toggles off)
- edit the hunk and quit the editor immediately with non-zero status
- commit

Editing a hunk puts you back on that hunk when done editing (issue5041)
To do that, we change two lines in a file, pretend to edit the second line,
exit, toggle the line selected at the end of the edit and commit.
The first line should be recorded if we were put on the second line at the end
of the edit.

  $ hg update -C .
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "foo" > x
  $ echo "hello world" >> x
  $ echo "bar" >> x
  $ cat <<EOF >testModeCommands

Testing the review option. The entire final filtered patch should show
up in the editor and be editable. We will unselect the second file and
the first hunk of the third file. During review, we will decide that
"lower" sounds better than "bottom", and the final commit should
reflect this edition.

  $ hg update -C .

Check ui.interface logic for the chunkselector

The default interface is text
  $ cp $HGRCPATH.pretest $HGRCPATH
  $ chunkselectorinterface() {
  > $PYTHON <<EOF
  > from mercurial import hg, ui;\
  > repo = hg.repository(ui.ui.load(), ".");\
  > print(repo.ui.interface("chunkselector"))
  > EOF
  > }
  $ chunkselectorinterface
  text

If only the default is set, we'll use that for the feature, too
  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = curses
  > EOF
  $ chunkselectorinterface
  curses

It is possible to override the default interface with a feature specific
interface
  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = text
  > interface.chunkselector = curses
  > EOF

  $ chunkselectorinterface
  curses

  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = curses
  > interface.chunkselector = text
  > EOF

  $ chunkselectorinterface
  text

If a bad interface name is given, we use the default value (with a nice
error message to suggest that the configuration needs to be fixed)

  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = blah
  > EOF
  $ chunkselectorinterface
