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.

6e302bb3a2 op_store: add a virtual root operation, similar to root commit
It seems obvious in hindsight to have a virtual root operation just
like we have a virtual root commit. It removes the same kind of
problems by making sure there's always a common ancestor (or multiple)
between any two commits.

I think the reason I didn't add a root operation from the beginning
was that there used to be a mandatory working-copy commit in the view
(this was before support for multiple workspaces).

Perhaps we should remove the "initialize repo" operation now. The only
difference between their view objects is that the "initialize repo"
operation adds the root commit as a head. We could add that to the
root operation, but then the root operation's value depends on the
commit backend.

c9af8bf43a view: drop tracking of public heads
We've had the public_heads for as long as we've had the View object,
IIRC (I didn't check), but we still don't use it for anything. I don't
have any concrete plans for using it either. Maybe our config for
immutable commits is good enough, or maybe we'll want something more
generic (like Mercurial's phases). For now, I think we should simplify
by removing it the storage for public heads.

b7c7b19eb8 view: migrate in-memory structure to per-remote branches map
There's a subtle behavior change. Unlike the original remove_remote_branch(),
remote_views entry is not discarded when the branches map becomes empty. The
reasoning here is that the remote view can be added/removed when the remote
is added/removed respectively, though that's not implemented yet. Since the
serialized data cannot represent an empty remote, such view may generate
non-unique content hash.

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

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