Summary: In preparation for unifying all workspace dependencies across all
crates, let's go ahead and move the jj-cli crate into its own new directory.
This will also be a nicer and more uniform layout as we add new `jj-*` crates.

Almost everyone calls the project "jj", and there seeems to be
consensus that we should rename the crates. I originally wanted the
crates to be called `jj` and `jj-lib`, but `jj` was already
taken. `jj-cli` is probably at least as good for it anyway.
Once we've published a 0.8.0 under the new names, we'll release 0.7.1
versions under the old names with pointers to the new crates names.
Since we abuse TOML table syntax to define function aliases, an identical
function alias can be found more than once in the merged config. The merged
config doesn't preserve the definition order, so we need to load aliases
table per layer.
Now we have 4 callers, I concluded this is common enough to add an
extension method. Still I think it's preferred to define config items in
src/config/*.toml if possible. It will catch typo of config keys.
We would like our default pager of `less -FRX` to also get passed
`LESSCHARSET=utf-8`. I don't like having defaults that the user can't
specify themselves, so this commits provides users with a way to pass
environment variables to their configured pager (or editor, or merge
tool, ...).
I didn't document this feature and I didn't add it to the config
schema because it seems it's going to be so rarely useful to users.
If FullCommandArgs is renamed to CommandNameAndArgs, the meaning of .args()
will get fuzzy. This also clarifies that the name part exists even if the
source command string is empty.
Accept an --include-defaults arg to enable including those.
Listing a nonexistent name is no longer an error, but does output a
warning to stderr when no config entries match to explain why there's no
other output.
The `git.fetch` and `git.push` keys can be used in the configuration file
for the default to use in `jj git fetch` and `jj git push` operations.
By defaut, "origin" is used in both cases.
Since per-repo config may contain CLI settings, it must be visible to CLI.
Therefore, UserSettings::with_repo() -> RepoSettings isn't used, and its
implementation is nullified by this commit.
#616
It's unclear whether parse_args() or its caller should update LayeredConfigs.
--config-toml is processed by callee to apply --color early. -R/--repository
will be processed by caller since it will instantiate WorkspaceLoader.
Maybe --config-toml can be removed from EarlyArgs, and handle_early_args()
just updates ui state based on --color argument?
Thinking of config precedence, we'll probably need to store "base" (default +
env_base + user) config and "override" (env_overrides + --config-toml) config
separately to support repo config. Suppose env_overrides() is a temporary
value, it's better to override any file-derived values with $JJ_ env.
When we fail to read the user's config, it seems obviously better to
use the default config than to not use it. It doesn't matter yet, but
it will matter when I've moved color configs out of `formatter.rs` and
into a `.toml` file. Without this change, we'd lose the default
coloring of the error message for config errors.
It should be more reliable than parsing a command string into array.
Also updated some of the doc example to use array syntax. I don't think
"C:/Program Files" was parsed properly, but might work thanks to Windows
magic.
It implements Deserialize because config.get() requires that. We could instead
add TryFrom<config::Value>, but we'll need Deserialize anyway if we want to
parse a struct containing FullCommandArgs.
I don't know if src/config.rs is the right place, but I feel it's slightly
better than messing up ui.rs.
Teach Ui's writing functions to write to a pager without touching the
process's file descriptors. This is done by introducing UiOutput::Paged,
which spawns a pager that Ui's functions can write to.
The pager program can be chosen via `ui.pager`. (defaults to Defaults to
$PAGER, and 'less' if that is unset (falling back to 'less' also makes
the tests pass).
Currently, commands are paginated if:
- they have "long" output (as defined by jj developers)
- jj is invoked in a terminal
The next commit will allow pagination to be turned off via a CLI option.
More complex pagination toggling (e.g. showing a pager even if the
output doesn't look like a terminal, using a pager for shorter ouput) is
left for a future PR.
Let's acknowledge everyone's contributions by replacing "Google LLC"
in the copyright header by "The Jujutsu Authors". If I understand
correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any
concerns).

It would be nice to be able to use snapshot testing and not have to
parse the output of `jj op log`. This patch lets us do that by
providing a new environment variable and config for overriding the
timestamps. Unlike `operation.hostname` and `operation.username`,
these are only meant for tests.
This makes the tests more hermetic, even though I don't think the
default values (taken from `whoami`) can break any tests (then we
would have already seen them break). Now we just need to make the
operation log's timestamps predictable and then we can start using
operation IDs in snapshot tests.
According to the NO_COLOR FAQ, "user-level configuration files [...] should
override $NO_COLOR." https://no-color.org/
Unfortunately this makes it harder to test the $NO_COLOR behavior since the
test environment isn't attached to a tty. We could allocate a pty or
LD_PRELOAD shim to intercept isatty(), but I feel it would be too much to do.

With this patch, the order is this:
`$JJ_EDITOR` environement variable
`ui.editor` config
`$VISUAL` environement variable
`$EDITOR` environement variable
`pico`
That matches git, except that git falls back to an editor determined
at compile time (usually `vi`) instead of using `pico`.
As I said in 095fb9fef4, removing support for `~/.jjconfig` was an
experiment. I've heard from a few people (including in #233) that they
would prefer to have configs in the home directory. This patch
therefore restores that functionality, except I added a `.toml`
extension to the file to clarify the expected format to users and
editors.
After this patch, we still allow configs in `$XDG_CONFIG_HOME` (and
the other paths used by `dirs::config_dir()`), but we error out there
are config files in both that location and `~/.jjconfig.toml`.
