07559f24ec Refuse to split an empty commit with jj split.
Rationale: The user may be confused by the empty diff in the diff editor
tool if they accidentally run `jj split` on a wrong (empty) commit.

3307696ba8 cli: parse out redundant "all:" revset modifier in arguments and templates
This also means "all:" is allowed in default revsets (such as "revsets.log"),
but that seems okay. In revset aliases, "all:" isn't allowed because aliases
may be expanded to sub-expression position.

Closes #3654

12b873e1ef cli: port "branch list" to template
Perhaps, this can be used to generate parsable branches list.

The hint for deleted branches isn't migrated to the template. I'm thinking of
moving it out of the loop and printed once at the end. If we want to generate
a hint in template, we'll probably need local_ref.tracking_remote_refs(), etc.
that return a list of RefNames.

8e4f75552d templater: add tracking methods to remote RefName
More tests will be added later as "branch list" templates.

In "log" template, we might want to see the number of "local" commits ahead
of any tracked remotes. It can be implemented later in a similar way (or as a
nested remote_refs list.)

70b517ca64 conflicts.rs: label conflict number and sides next to conflict markers
For example, 

```
<<<<<<< Conflict 1 of 3
+++++++ Contents of side #1
left 3.1
left 3.2
left 3.3
%%%%%%% Changes from base to side #2
-line 3
+right 3.1
>>>>>>>
```

or

```
<<<<<<< Conflict 1 of 1
%%%%%%% Changes from base to side #1
-line 3
+right 3.1
+++++++ Contents of side #2
left 3.1
left 3.2
left 3.3
>>>>>>>
```

Currently, there is no way to disable these, this is TODO for a future
PR. Other TODOs for future PRs: make these labels configurable. After
that, we could support a `diff3/git`-like conflict format as well, in
principle.

Counting conflicts helps with knowing whether you fixed all the
conflicts while you are in the editor.

While labeling "side #1", etc, does not tell you the commit id or
description as requested in #1176, I still think it's an improvement.
Most importantly, I hope this will make `jj`'s conflict format less
scary-looking for new users.

I've used this for a bit, and I like it. Without the labels, I would see
that the two conflicts have a different order of conflict markers, but I
wouldn't be able to remember what that means. For longer diffs, it can
be tricky for me to quickly tell that it's a diff as opposed to one of
the sides. This also creates some hope of being able to navigate a
conflict with more than 2 sides.

Another not-so-secret goal for this is explained in
https://github.com/martinvonz/jj/pull/3109#issuecomment-2014140627. The
idea is a little weird, but I *think* it could be helpful, and I'd like
to experiment with it.

4db068e7f7 templater: expose RefTarget methods through RefName type
I considered adding RefTarget template type, but some of the methods naturally
fit to RefName. For example, a conflicted branch name is decorated as "??", so
it makes sense to add branch.conflict() instead of branch.target().conflict().

I'm not pretty sure how many RefName methods we'll need to add to port the
current branch listing, but there will be .tracked(), .tracking_local_present(),
.ahead_by(), and .behind_by().

714bc0a9e6 rebase: add move_commits function to perform rebasing
The `move_commits` function accepts a set of target commits to shift to
a new location given by `new_parents` and `new_children`. The roots of
the target set will be reparented onto `new_parents`. `new_children`
will then be reparented onto the heads of the target set.

The commits will be rebased in reverse topological order based on the
new set of parents of each commit, which avoids the need for multiple
sets of rebase operations.

9d7ed54f8e git_backend: add a README to conflicted commits
When you use e.g. `git switch` to check out a conflicted commit,
you're going to end up with the `.jjconflicts-*` directories in your
working copy. It's probably not obvious what those mean. This patch
adds a README file to the root tree to try to explain to users what's
going on and how to recover.

The authoritative information about conflicts is stored in the
`jj:trees` commit header. The contents of conflicted commits is only
used for preventing GC. We can therefore add contents to the tree
without much consequence.

a2c49abbbe Add short a -e alias for --edit to prev and next
I'm not sure if this was an intentional omission, but I think it would be
useful to have `-e` as a short flag for `--edit`. I don't usually edit commits,
but I do use `prev` and `next` with edit to navigate to a commit that I want to
squash. Often this is easier than typing `--from` and `--into` plus the change
IDs.

If people want to edit commits we shouldn't stand in their way.

3f0e4de64a Allow advance_branches tests to be parameterized
In a future commit these tests will run with both `jj commit` and `jj new` since
both will have the same semantics for advancing the branch pointer.

Parameterizing the tests allows us to run both variants without duplicating the
test bodies. Since the commit IDs are different when `jj describe` + `jj new`
is used instead of `jj commit`, this commit also drops the commit IDs from the
test snapshots. This is fine because the commit IDs are not important for these
tests.

bbd9c7c7cb Implement advance-branches for jj commit
## Feature Description

If enabled in the user or repository settings, the local branches pointing to the
parents of the revision targeted by `jj commit` will be advanced to the newly
created commit. Support for `jj new` will be added in a future change.

This behavior can be enabled by default for all branches by setting
the following in the config.toml:

```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
```

Specific branches can also be disabled:
```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
disabled-branches = ["main"]
```

Branches that match a disabled pattern will not be advanced, even if they also
match an enabled pattern.

This implements feature request #2338.

ddfdf5e357 cli: allow snapshot.max-new-file-size to be a raw u64
Previously, this command would work:

    jj --config-toml='snapshot.max-new-file-size="1"' st

And is equivalent to this:

    jj --config-toml='snapshot.max-new-file-size="1B"' st

But this would not work, despite looking like it should:

    jj --config-toml='snapshot.max-new-file-size=1' st

This is extremely confusing for users.

This config value is deserialized via serde; and while the `HumanByteSize`
struct allegedly implemented Serde's `visit_u64` method, it was not called by
the deserialize visitor. Strangely, adding an `visit_i64` method *did* work, but
then requires handling of overflow, etc. This is likely because TOML integers
are naturally specified in `i64`.

Instead, just don't bother with any of that; implement a `TryFrom<String>`
instance for `HumanByteSize` that uses `u64::from_str` to try parsing the string
immediately; *then* fall back to `parse_human_byte_size` if that doesn't work.
This not only fixes the behavior but, IMO, is much simpler to reason about; we
get our `Deserialize` instance for free from the `TryFrom` instance.

Finally, this adjusts the test for `max-new-file-size` to now use a raw integer
literal, to ensure it doesn't regress. (There are already in-crate tests for
parsing the human readable strings.)
