d66fcf2ca0 compile integration tests as a single binary
this greatly speeds up the time to run all tests, at the cost of slightly larger recompile times for individual tests.

this unfortunately adds the requirement that all tests are listed in `runner.rs` for the crate.
to avoid forgetting, i've added a new test that ensures the directory is in sync with the file.

 ## benchmarks

before this change, recompiling all tests took 32-50 seconds and running a single test took 3.5 seconds:

```
; hyperfine 'touch lib/src/lib.rs && cargo t --test test_working_copy'
  Time (mean ± σ):      3.543 s ±  0.168 s    [User: 2.597 s, System: 1.262 s]
  Range (min … max):    3.400 s …  3.847 s    10 runs
```

after this change, recompiling all tests take 4 seconds:
```
;  hyperfine 'touch lib/src/lib.rs ; cargo t --test runner --no-run'
  Time (mean ± σ):      4.055 s ±  0.123 s    [User: 3.591 s, System: 1.593 s]
  Range (min … max):    3.804 s …  4.159 s    10 runs
```
and running a single test takes about the same:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test runner -- test_working_copy'
  Time (mean ± σ):      4.129 s ±  0.120 s    [User: 3.636 s, System: 1.593 s]
  Range (min … max):    3.933 s …  4.346 s    10 runs
```

about 1.4 seconds of that is the time for the runner, of which .4 is the time for the linker. so
there may be room for further improving the times.

bb72def464 cli rebase: tests for weird ancestry for -s and -b 2023-11-28 21:36:51 -08:00

22abbbea9b cli rebase -r: add tests for weird ancestry, record a bug, fix a comment
Note that one of the new tests panics; this is a newly discovered bug.

In Git, a commit's direct parent is allowed to also be an indirect ancestor
at the same time. `jj` currently tries to prevent this situation, but does
allow it. The correctness of `rebase -r A -d descendant_of_A` currently depends
on this jj-specific behavior; we should change that.

6aef4bb52e cli rebase: do not allow -r --skip-empty
This follows up on 3967f63 (see that commit's description for more
motivation) and e79c8b6.

In a discussion linked below, it was decided that forbidding `-r --skip-empty`
entirely is preferable to the mixed behavior introduced in 3967f63.

8bc3f5fd67 cli rebase: Allow jj rebase -r to rebase a commit onto a descendant
#1188

There are some additional test changes because children and descendants are now
rebased before the commit itself.

7a3e72415c cli: send status messages to stderr, specify stdout/stderr explicitly
Many of &mut UI can be changed to immutable borrows, but I'm not gonna
update them in this patch.

e3c85d6ecc revset: convert root symbol to function
The idea is that we can fully eliminate special symbols that would otherwise
shadow user branches, tags, or change ID prefixes.

Closes #2095

6fa8a25839 cli templates: include branches in short commit description
They are shown next to the change and commit id, since they are other names the
commit can be referred by. 

The description is separated from the branches by a ` | ` when there are
branches, so that one can tell the branches from the description without color.

The result looks like this: ![image](https://github.com/martinvonz/jj/assets/4123047/a38aff7b-2b47-49e6-8461-c42e8eb535a4)

Thanks to @ilyagr for noticing that they should be moved.
