This PR contains various improvements for the markdown preview (some of
which were originally part of #7601).
Some improvements can be seen in the video (see also release notes down
below):


https://github.com/zed-industries/zed/assets/53836821/93324ee8-d366-464a-9728-981eddbfdaf7

Release Notes:
- Added action to open markdown preview in the same pane
- Added support for displaying channel notes in markdown preview
- Added support for displaying the current active editor when opening
markdown preview
- Added support for scrolling the editor to the corresponding block when
double clicking an element in markdown preview
- Improved pane creation handling when opening markdown preview
- Fixed markdown preview displaying non-markdown files

This PR updates the `extension.toml` to allow specifying multiple
languages for a language server to work with.

The `languages` field takes precedence over `language`. In the future
the `language` field will be removed.

As part of this, the Emmet extension has been extended with support for
PHP and ERB.

- Fixed #9729 and #10193

This commit fixes an issue where the string splitting function was
handling characters in the input string improperly. We adjusted the use
of the `take_while` function to calculate the length of the numeric
prefix, rather than directly splitting the string, thus correctly
splitting the string into a numeric prefix part and the remaining part

This increases search context from 1 above, 2 below, to 2 above and 2
below, matching the Sublime Text search results.

Release Notes:

- Increased search result context from 3 lines to 4 lines

For #4965

There are still some minor issues: 
1. When change the surround and delete the surround, we should also
decide whether there are spaces inside after deleting/replacing
according to whether it is open parentheses, and replace them
accordingly, but at present, delete and change, haven't done this
adaptation for current pr, I'm not sure if I can fit it in the back or
if it needs to be fitted together.
2. In the selection mode, pressing s plus brackets should also trigger
the Add Surrounds function, but this MR has not adapted the selection
mode for the time being, I think we need to support different add
behaviors for the three selection modes.(Currently in select mode, s is
used for Substitute)
3. For the current change surrounds, if the user does not find the
bracket that needs to be matched after entering cs, but it is a valid
bracket, and will wait for the second input before failing, the better
practice here should be to return to normal mode if the first bracket is
not found
4. I reused BracketPair in language, but two of its properties weren't
used in this mr, so I'm not sure if I should create a new struct with
only start and end, which would have less code

I'm not sure which ones need to be changed in the first issue, and which
ones can be revised in the future, and it seems that they can be solved

This PR makes Zed respect the language server's capabilities when
calling the `GetReferences` command (used in "Find All References",
etc.).

This fixes a crash that could occur when using Zed with Gleam v1.0.

At the moment, the editor scrollbar is 12px wide. One pixel is allocated
for the left border, so we have 11 pixels to display markers. It's not
enough to make three even marker columns (git, highlights, diagnostics)
that fully fill the scrollbar, so the current implementation allocates 3
pixels to each column.

As the result, we have 2 spare pixels on the right (before #10080 they
were occupied by the diagnostics column). Making the scrollbar just one
pixel wider allows us to give one additional pixel to each marker column
and make markers more pronounced ("as is" on the left, "to be" on the
right):

<img width="115" alt="zed-scrollbar-markers-1px"
src="https://github.com/zed-industries/zed/assets/2101250/4bdf0107-c0f1-4c9c-9063-d2ff461e1c32">

Other options:
- Remove scrollbar thumb border. That'll give us one missing pixel to
make markers wide and even. I, personally, prefer this option, but
themes now have `scrollbar.thumb.border` colors that differ from
`scrollbar.thumb.background` for some reason. This theme setting becomes
deprecated in this case. For the reference: VS Code doesn't have
scrollbar slider borders, IntelliJ IDEA does have them.
- Don't try to make markers evenly wide. For instance, IntelliJ uses
very narrow git-diff markers that are separated from other markers. But
it requires much wider scrollbar (it's 20px in IDEA).
- Use the spare two pixels to make diagnostic markers wider (it's the
pre #10080 approach), or split them between the highlight and diagnostic
markers (have 3px+4px+4px marker columns).
- Do nothing. It leaves us with two unused pixels :(

We ran into a panic when deleting text that was just generated by a code
action.

This fixes it by ensuring we don't run into a 0-minus-1 panic when a
buffer_range is empty.

This fixes #10177 by sending along the correct diagnostics when querying
the language server for diagnostics for a given cursor location.

Turns out that `gopls` takes the `range`, `source`, `message` of the
diagnostics sent along to check whether it has any code actions for the
given location.

Release Notes:

- Fixed "quickfix" code actions that were based on diagnostics not
showing up in Go files.

Due to peculiarities in handling of terminal panes (namely the fact that
they are not actually tracked by the Workspace::active_pane member), it
was possible to get into a state where status bar items "lost track" of
an active pane item; one way to reproduce it was to open a new terminal
via "workspace: new terminal" with a pane open in a central view; once a
new terminal is opened, the language selector and line number indicator
lose track of an active item. Focusing central view does nothing - it
will only go away after switching a tab in the central view.

To remedy this, we now always notify the status bar items of a pane
focus change, even if Workspace::active_pane points to the same pane.

Release Notes:

- Fixed status bar focus issues when spawning a terminal via `workspace:
new terminal` action.

This is another variant for this [original
PR](https://github.com/zed-industries/zed/pull/10091) to add settings to
show/hide navigation history buttons that puts the settings under a new
section called `tab_bar`:

```
  "tab_bar": {
    // Whether or not to show the navigation history buttons.
    "show_nav_history_buttons": true
  }
```

Fixes #4380

Parts im still unsure about:
- [x] where exactly I should call `on_lsp_start`/`on_lsp_end`
- [x] how to handle things better than `let is_references =
TypeId::of::<R>() == TypeId::of::<GetReferences>();`, which feels very
janky
- [x] I want to have the message be something like `"Finding references
to [...]"` instead of just `textDocument/references`, but I'm not sure
how to retrieve the name of the symbol that's being queried
- [ ] I think the bulk of the runtime is occupied by `let result =
language_server.request::<R::LspRequest>(lsp_params).await;`, but since
`ModelContext` isn't passed into it, I'm not sure how to update progress
from within that function
- [x] A good way to disambiguate between multiple calls to the same lsp
function; im currently using the function name itself as the unique
identifier for that request, which could create issues if multiple
`textDocument/references` requests are sent in parallel

Any help with these would be deeply appreciated!

Release Notes:

- Adds a status indicator for LSP actions

While working towards fixes for the image viewer, @mikayla-maki and I
discovered that we didn't have `object-fit: scale-down` implemented.

only the bounds width is updating on layout change that I haven't fully
chased down.

Release Notes:

- Fixed an incorrect reference to the `soft_wrap` setting in the default
settings documentation.

1. They now will not go off-screen
2. You can scroll long messages.
3. Only one notification per language server is shown at a time
4. The title/text are now distinguished visually
5. You can copy the error message to the clipboard

Release Notes:

([#10090](https://github.com/zed-industries/zed/issues/10090)).

We want Zed to be opinionated and low-configuration. Your code editor
should get out of the way, and just do the right thing.

However, some ecosystems aren't opinionated enough for us to
automatically detect the right way to format your code, so let's turn it
off.

Release Notes:

- Disabled `format_on_save` by default in C and C++.

@algora-pbc /claim #4273

This is a work-in-progress. The process for `gn` command is:

- maintain updated vim.workspace_state.search.initial_query
- modify editor.select_next_state with
vim.workspace_state.search.initial_query
- use editor.select_next()
- merge selections
- set editor.select_next_state to previous state

To make this possible, several private members and editor structures are
made public. `gN` is not yet implemented and the cursor still does not
jump to the next selection in the first use.

Maybe there is an better way to do this?

This PR adds the ability for extensions to implement
`language_server_workspace_configuration` to provide workspace
configuration to the language server.

We've used the Dart extension as a motivating example for this, pulling
it out into an extension in the process.

Release Notes:

- Removed built-in support for Dart, in favor of making it available as
an extension. The Dart extension will be suggested for download when you
open a `.dart` file.

This PR adds more documentation for various constructs in the
`zed_extension_api` crate.

`wit_bindgen` is able to generate doc comments on the Rust constructs
using the the doc comments in the WIT files, so we're able to leverage
that for the majority of the constructs that we expose.

This fixes #9786 by using an invocation of `/usr/bin/env` that's
supported by macOS 12.

As it turns out, on macOS 12 (and maybe 13?) `/usr/bin/env` doesn't
support the `-0` flag. In our case it would silently fail, since we
`exit 0` in our shell invocation and because the program we run and
whose exit code we check is the `$SHELL` and not `/usr/bin/env`.

What this change does is to drop the `-0` and instead split the
environment on `\n`. This works even if an environment variable contains
a newline character because that would then be escaped.

Release Notes:

- Fixed Zed not picking up shell environments correctly when running on
macOS 12. ([#9786](https://github.com/zed-industries/zed/issues/9786)).

Release notes:

- Fixed a crash when joining two consecutive lines
([#9692](https://github.com/zed-industries/zed/pull/9692)).


This crash is not caused by `vim` or `editor`'s code logic, `join_line`
logic is okay, I found that the crash is caused by a refresh of git
`diff` after every update, hhen git diff generates hunks, it will look
for the cursor to the beginning of a line, and judge that if the cursor
result column is greater than 0, that is, it is not the beginning of a
line, it will correct the row to the next line, I think before we forgot
here that I need to adjust the column to 0 at the same time, otherwise
it is easy to go out of bounds, I am not sure if I need to add more
tests for this method, I can add if I need to, but I feel that this case
is a bit extreme

#10080 introduced a minor change in how the min marker height is
enforced. Before the change, it was applied to the aggregated marker,
but after the change it's applied to each individual marker before
aggregation.

The difference is not noticeable on small files, where even single row
markers are higher than `MIN_MARKER_HEIGHT`, but it leads to visible
differences in large files with repeating blocks of highlighted and
not-highlighted blocks, like in [this
case](https://github.com/zed-industries/zed/pull/9080#issuecomment-2006796376).

This PR fixes how the `MIN_MARKER_HEIGHT` is applied.
