a0cf054a45 internal/lsp: initialize CodeActionProvider with supported actions
Send the code action kinds that we support, if codeActionLiteralSupport
is specified. Editors may use the CodeActionKinds that we support to
determine UI layout for example.

1f0dd0289f internal/lsp: start handling watched file change events
Now we register for and handle didChangeWatchedFiles "change"
events. We don't handle "create" or "delete" yet.

When a file changes on disk, there are two basic cases. If the editor
has the file open, we want to ignore the change since we need to
respect the file contents in the editor. If the file isn't open in the
editor then we need to re-type check (and re-diagnose) any packages it
belongs to.

We will need special handling of go.mod changes, but start with
just *.go files for now.

I'm putting the new behavior behind an initialization flag while it is
under development.

Updates golang/go#31553

caa95bb40b internal/lsp: add completions of unimported std lib pkgs
Unimported packages may be suggested as completion items. Since these
are not yet imported, they should be ranked lower than other candidates.

They also require an additional import statement to be valid, which is
provided as an AdditionalTextEdit.

Adding this import does not use astutil.AddNamedImport, to avoid
editing the current ast and work even if there are errors. Additionally,
it can be hard to determine what changes need to be made to the source
document from the ast, as astutil.AddNamedImport includes a merging
pass. Instead, the completion item simply adds another import
declaration.

09f9cfa882 internal/lsp: set initialized state
Set the server state to initialized so that dynamic configuration
requests will be sent to the client.

Rename the mutex that guards state. The state field was previously named
initialized, so it only makes sense to similarly rename the mutex that
guards the state field.

Always unlock stateMu before calling other functions so that callees
that need to check state can acquire the lock.

4f9eeaf1bf internal/lsp: add documentation to completion items
This change adds documentation to the completion items. This normally
should be done in completionItem/resolve, since it takes more time to
compute documentation. However, I am not sure if that latency incurred
by pre-computing documentation is actually significantly more than the
latency incurred by an extra call to 'completionItem/resolve'. This
needs to be investigated, so we begin by just precomputing all of the
documentation for each item.

4298585011 internal/lsp: provide deep completion candidates
Deep completion refers to searching through an object's fields and
methods for more completion candidates. For example:

func wantsInt(int) { }
var s struct { i int }
wantsInt(<>)

Will now give a candidate for "s.i" since its type matches the
expected type.

We limit to three deep completion results. In some cases there are
many useless deep completion matches. Showing too many options defeats
the purpose of "smart" completions. We also lower a completion item's
score according to its depth so that we favor shallower options. For
now we do not continue searching past function calls to limit our
search scope. In other words, we are not able to suggest results with
any chained fields/methods after the first method call.

Deep completions are behind the "useDeepCompletions" LSP config flag
for now.

This change sends the expected boolean value for 'renameProvider'

When a client does not send 'prepareSupport' in its initial

set 'renameProvider' to true regardless of the value of prepareSupport.

34437f544f internal/lsp: refactor server.go to separate into LSP categories
This change separates the different behaviors of server.go by the
categories defined in the spec. This allows us to differentiate more
easily between the language features and the text synchronization code.

I also renamed the "Symbols" function to "Symbol", which fits with the
specification
(https://microsoft.github.io/language-server-protocol/specification#workspace_symbol),
and makes clearer the distinction between DocumentSymbols and Symbol.
