rust-discovery: takefullsample() core implementation

take_full_sample() browses the undecided set in both directions: from
its roots as well as from its heads.

Following what's done on the Python side, we alter update_sample()
signature to take a closure returning an iterator: either ParentsIterator
or an iterator over the children found in `children_cache`. These constructs
should probably be split off in a separate module.

This is a first concrete example where a more abstract graph notion (probably
 a trait) would be useful, as this is nothing but an operation on the reversed
DAG.

A similar motivation in the context of the discovery
process would be to replace the call to dagops::range in
`add_missing_revisions()` with a simple iteration over descendents, again an
operation on the reversed graph.

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

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)
  text

  $ cp $HGRCPATH.pretest $HGRCPATH
