This pull request introduces the ability to add flaps, custom foldable
regions whose first foldable line can be associated with:
- A toggle in the gutter
- A trailer showed at the end of the line, before the inline blame
information
https://github.com/zed-industries/zed/assets/482957/c53a9148-f31a-4743-af64-18afa73c404c
To achieve this, we changed `FoldMap::fold` to accept a piece of text to
display when the range is folded. We use this capability in flaps to
avoid displaying the ellipsis character.
We want to use this new API in the assistant to fold context while still
giving visual cues as to what that context is.

To avoid confusion and bugs when converting between various row `u32`'s,
use different types for each.
Further PRs should split `Point` into buffer and multi buffer variants
and make the code more readable.

Release Notes:
- vim: Added support for the changelist. `g;` and `g,` to the
previous/next change
- vim: Added support for the `'.` mark
- vim: Added support for `gi` to resume the previous insert
This PR renames `language::Buffer::new` to `language::Buffer::local` and
simplifies its interface. Instead of taking a replica id (which should
always be 0 for the local case) and a `BufferId`, which was awkward and
verbose to construct, it simply takes text and a `cx`.
It uses the `cx` to derive a `BufferId` from the `EntityId` associated
with the `cx`, which should always be positive based on the following
analysis...
We convert the entity id to a u64 using this method on `EntityId`, which
is defined by macros in the `slotmap` crate:
```rust
pub fn as_ffi(self) -> u64 {
(u64::from(self.version.get()) << 32) | u64::from(self.idx)
}
```
If you look at the type of `version` in `KeyData`, it is non-zero:
```rust
#[derive(Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Hash)]
pub struct KeyData {
idx: u32,
version: NonZeroU32,
}
```
This commit also adds `Context::reserve_model` and
`Context::insert_model` to determine a model's entity ID before it is
created, which we need in order to assign a `BufferId` in the background
when loading a buffer asynchronously.

Fixes https://github.com/zed-industries/zed/issues/9792
This pull request moves the computation of scrollbar markers off the
main thread, to prevent them from grinding the editor to a halt when we
have a lot of them (e.g., when there are lots of search results on a
large file). With these changes we also avoid generating multiple quads
for adjacent markers, thus fixing an issue where we stop drawing other
primitives because we've drawn too many quads in the scrollbar.
Release Notes:
- Improved editor performance when displaying lots of search results,
diagnostics, or symbol highlights in the scrollbar
([#9792](https://github.com/zed-industries/zed/issues/9792)).

This pull request introduces a new `InlineCompletionProvider` trait,
which enables making `Editor` copilot-agnostic and lets us push all the
copilot functionality into the `copilot_ui` module. Long-term, I would
like to merge `copilot` and `copilot_ui`, but right now `project`
depends on `copilot`, which makes this impossible.
The reason for adding this new trait is so that we can experiment with
other inline completion providers and swap them at runtime using config
settings.
Please, note also that we renamed some of the existing copilot actions
to be more agnostic (see release notes below). We still kept the old
actions bound for backwards-compatibility, but we should probably remove
them at some later version.
Also, as a drive-by, we added new methods to the `Global` trait that let
you read or mutate a global directly, e.g.:
```rs
MyGlobal::update(cx, |global, cx| {
});
```
Release Notes:
- Renamed the `copilot::Suggest` action to
`editor::ShowInlineCompletion`
- Renamed the `copilot::NextSuggestion` action to
`editor::NextInlineCompletion`
- Renamed the `copilot::PreviousSuggestion` action to
`editor::PreviousInlineCompletion`
- Renamed the `editor::AcceptPartialCopilotSuggestion` action to
`editor::AcceptPartialInlineCompletion`

### Problem
After transitioning Zed to GPUI 2, we started noticing that interacting
with the mouse on many UI elements would lead to a pretty annoying
flicker. The main issue with the old approach was that hover state was
calculated based on the previous frame. That is, when computing whether
a given element was hovered in the current frame, we would use
information about the same element in the previous frame.
However, inspecting the previous frame tells us very little about what
should be hovered in the current frame, as elements in the current frame
may have changed significantly.
### Solution
This pull request's main contribution is the introduction of a new
`after_layout` phase when redrawing the window. The key idea is that
we'll give every element a chance to register a hitbox (see
`ElementContext::insert_hitbox`) before painting anything. Then, during
the `paint` phase, elements can determine whether they're the topmost
and draw their hover state accordingly.
We are also removing the ability to give an arbitrary z-index to
elements. Instead, we will follow the much simpler painter's algorithm.
That is, an element that gets painted after will be drawn on top of an
element that got painted earlier. Elements can still escape their
current "stacking context" by using the new `ElementContext::defer_draw`
method (see `Overlay` for an example). Elements drawn using this method
will still be logically considered as being children of their original
parent (for keybinding, focus and cache invalidation purposes) but their
layout and paint passes will be deferred until the currently-drawn
element is done.
With these changes we also reworked geometry batching within the
`Scene`. The new approach uses an AABB tree to determine geometry
occlusion, which allows the GPU to render non-overlapping geometry in
parallel.
### Performance
Performance is slightly better than on `main` even though this new
approach is more correct and we're maintaining an extra data structure
(the AABB tree).

Release Notes:
- Fixed a bug that was causing popovers to flicker.

Prepare for git diff hunk highlights by grouping all inlay highlight
properties into one struct, and removing the dead background highlight
code.
Release Notes:
- N/A
- Moves languages module from `zed` into a separate crate. That way we
have less of a long pole at the end of compilation.
- Removes moot dependencies on editor/picker. This is totally harmless
and might help in the future if we decide to decouple picker from
editor.
Before:
```
Number of crates that depend on 'picker' but not on 'editor': 1
Total number of crates that depend on 'picker': 13
Total number of crates that depend on 'editor': 30
```
After:
```
Number of crates that depend on 'picker' but not on 'editor': 5
Total number of crates that depend on 'picker': 12
Total number of crates that depend on 'editor': 26
```
The more crates depend on just picker but not editor, the better in that
case.
Release Notes:
- N/A
Hopefully this makes it a bit easier for new contributors to dive into
the codebase :)

This PR adds the initial support for loading extensions in Zed.
### Extensions Directory
Extensions are loaded from the extensions directory.
The extensions directory has the following structure:
```
extensions/
installed/
extension-a/
grammars/
languages/
extension-b/
themes/
manifest.json
```
The `manifest.json` file is used internally by Zed to keep track of
which extensions are installed. This file should be maintained
automatically, and shouldn't require any direct interaction with it.
Extensions can provide Tree-sitter grammars, languages, and themes.

This change implements the vim
[motion](https://github.com/vim/vim/blob/master/runtime/doc/motion.txt)
commands to move the cursor to the top, middle and bottom of the visible
view. This feature is requested in
https://github.com/zed-industries/zed/issues/4941.
This change takes inspiration from
[crates/vim/src/normal/scroll.rs](https://github.com/zed-industries/zed/blob/main/crates/vim/src/normal/scroll.rs).
A note on the behavior of these commands: Because
`NeovimBackedTestContext` requires compatibility with nvim, the current
implementation causes slightly non-standard behavior: it causes the
editor to scroll a few lines. The standard behavior causes no scrolling.
It is easy enough to account for the margin by adding
`VERTICAL_SCROLL_MARGIN`. However, doing so will cause test failures due
to the disparity between nvim and zed states. Perhaps
`NeovimBackedTestContext` should have a switch to be more tolerant for
such cases.
Release Notes:
- Added support for moving to top, middle and bottom of the screen in
vim mode (`H`, `M`, and `L`)
([#4941](https://github.com/zed-industries/zed/issues/4941)).
