run-tests: work around the Windows firewall popup for server processes

Windows doesn't have a `python3` executable, so cc0b332ab9fc attempted to work
around the issue by copying the current python to `python3.exe`.  That put it in
`_tmpbindir` because of failures in `test-run-tests.t` when using `_bindir`,
which looked like a process was trying to open it to write out a copy while it
was in use.  (Interestingly, I couldn't reproduce this running the test by
itself in a loop for a couple of hours, but it happens constantly when running
all tests.)  The problem with using `_tmpbindir` is that it is the randomly
generated path for the test run, and instead of Windows Firewall remembering the
executable signature or image hash when allowing the process to open a server
port, it apparently remembers the image path.  That means every run will trigger
a popup to allow it, which is bad for firing off a test run and walking away.

I tried to symlink to the python executable, but that currently requires admin
priviledges[1].  This will prompt the first time if the underlying python binary
has never opened a server port, but appears to avoid it on subsequent runs.

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 all lines twice (to check that it does nothing)
- edit the hunk and quit the editor immediately with non-zero status
- commit

Newly added files can be selected with the curses interface

  $ hg update -C .
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "hello" > x

  $ hg st
  A x
  ? testModeCommands
  $ hg commit -i  -m "newly added file" -d "0 0"
  $ hg st

Test toggling all selections works

- Change one line
- Add an extra line at the end
- Unselect all
- Select the extra line at the end
- Toggle all selections (so the extra line at the is unselected and the modified line is selected)
- 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.

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.

Check ui.interface logic for the chunkselector

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

If TERM=dumb, we use text, even if the config says curses
  $ chunkselectorinterface
  curses
  $ TERM=dumb chunkselectorinterface
  text
(Something is keeping TERM=dumb in the environment unless I do this, it's not
scoped to just that previous command like in many shells)
  $ TERM=xterm 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
  invalid value for ui.interface: blah (using text)
