SourceKit-LSP supports explicit cancellation and thus we don’t need to do the implicit cancellation of cursor info and related identifiers on subsequent requests.
The changes in #945 changed the dependencies but did not correct them in
the CMakeLists.txt resulting in a broken build. Resynchronise the
dependencies across Package.swift and CMake.
When receiving a `CancellationNotification`, we cancel the task that handles the request with that ID.
This will cause `cancel_notification` to be sent to sourcekitd or a `CancellationNotification` to be sent to `clangd`, which ultimately cancels the request.

With this change, opening and editing a document no longer causes a non-cancellable AST build. Instead, all semantic information is retrieved via requests that can be cancelled (after we implement cancellation).
This allows us to cancel the semantic tokens request. It is also the last step to allow us to open and edit documents in syntactic-only mode.
It also means that we no longer need to send a `WorkspaceSemanticTokensRefreshRequest` to the client after sourcekitd has updated its semantic tokens since with the new design the `DocumentSemanticTokensRangeRequest` will simply return the results once it has the updated semantic token.
OSLog is the suggesting logging solution on Apple platforms and we should be using it there, taking advantage of the different log levels and privacy masking.
Switch sourcekit-lsp to use OSLog on Apple platforms and implement a logger that is API-compatible with OSLog for all uses in sourcekit-lsp and which can be used on non-Darwin platforms.
The goal of this commit is to introduce the new logging API. There are still improvements about what we log and we can display more privacy-insensitive information after masking. Those changes will be in follow-up commits.
Add `.swift-format` to the repo and format the repo with `swift-format`.
This commit does not add any automation to enforce formatting of sourcekit-lsp in CI. The goal of this commit is to get the majority of source changes out of the way so that the diff of actually enforcing formatting will have fewer changes or conflicts.
Since Musl is sufficiently different from Glibc (see https://wiki.musl-libc.org/functional-differences-from-glibc.html), it requires a different import, which now should be applied to files that have `import Glibc` in them.
Musl is a low footprint libc that's used in Linux distributions such as Alpine Linux, which allows producing fairly small container images. Additionally, unlike Glibc, musl allows full static linking, meaning apps can be easily distributed to an arbitrary Linux distribution that may have a version of Glibc incompatible with the one that Swift is usually built with or no Glibc installed at all.
We weren’t semantically highlighting references to actors because we missed the `ref_actor` case from the sourcekitd `annotations` response.

SKSupport now requires a link against Foundation, update the build
system to track that dependency.

The dependency on `TSCUtility` was strictly for identifying the platform
of execution. This logic is relatively self-contained and effectively an
extension over an enumeration. Replicate this logic with updates for new
syntactic improvements. This allows us to partially reduce dependency on
swift-tools-support-core. The dependency on TSCBasic is more complicated
to remove due to the extensive use of `AbsolutePath`.

Explicitly import interfaces from TSCBasic which now allows us to
identify all the swift-tools-support-core interfaces which are in
use in SourceKit-LSP.
Replace the use of the deprecated `Lock` from swift-tools-support-core
with `NSLock`. The benefit of the deprecated interface was the
`withLock` function which is easily replicated and very unlikely to
change. By doing so we avoid the warnings about `Lock` being deprecated
when building SourceKit-LSP.
This adjusts the sourcekit-lsp build to use static linking for the
internal libraries. It is not currently possible to build
SourceKitLSP.dll as that requires re-exporting the interfaces from the
consumed modules. However, this allows us to reduce the overall size of
the distribution of SourceKit-LSP by ~1 MiB and reduces the
distributed file set. The values here assume partial static linking of
swift-package-manager, which helps reduce the total size.

The swift project uses a minimum of CMake 3.19.6, and the current CMake
release is 3.22. Update the CMake requirement to a newer version and
remove the workaround for older releases of CMake.
This is an implementation of LSP's semantic tokens for Swift. Both
lexical and semantic tokens are provided by using the syntaxmap and the
semantic annotations provided as part of SourceKit's open responses and
document update notifications.
While lexical tokens are parsed and stored in the DocumentManager
synchronously, semantic tokens are provided asynchronously. If an edit
occurs, tokens are automatically shifted by the DocumentManager. This is
especially relevant for lexical tokens, which are updated in deltas.
In addition, unit tests are added that assert that both lexical and
semantic tokens are provided and shifted correctly upon edits.
