Rebecca Stambler a03874c3f7 internal/lsp: clean up unused parameters
Noticed these when I enabled the "unusedparams" analyzer. Not really
necessary to fix most of them, but seemed harmless.

Danish Dua 1610a49f37 internal/lsp/source/completion: use a minimum budget of 10ms for shallow completions
Type-checking can be very expensive for large packages and leave no
budget for shallow completions. This change adds a minimum budget of
10ms so we show the user at least some shallow suggestions.

Danish Dua ecd9fd270d internal/lsp/source: ignore empty package names for completion
Workspace packages seem to contain an empty package name when no

irrelevant completion suggestion.

This change eliminates any special scenarios where we need to call
c.item instead of going through deepSearch by adding support for all the
cases in deepSearch and c.addItem (previously c.item).

comments match the prefix (or fuzzy match depending on user settings)

Danish Dua c43c25c95a internal/lsp/source: run deep completions before unimported completions
Unimported completions are expensive and can use up a large portion of
completion budget just to find initial deep search candidates. This
change moves these expensive operations which search through the module
cache to after normal deep completions so we search through more useful
candidates first.

Danish Dua 8d73f17870 internal/lsp: move package selection to before type checking
This change moves package selection to before type checking so we don't
unnecessarily type-check both variants of a package. As a result, exec
time and memory usage for features making calls to GetParsedFile are cut
by half since we only type check either the narrowest or the widest
package.

Danish Dua f5e916c686 internal/lsp/source/completion: move search path to candidate
This change refactors deep completion to move search path to a candidate
instead of pointing to it in search queue. This removes the idea of
"being in deep completion" and instead a deep candidate is just a
candidate with a path from search root.

Danish Dua a1f7ab681e internal/lsp/source/completion: move deep search to end of completion
Currently, we deep search top level candidates as soon as they're found,
which isn't necessarily leading to an overall breadth first search
approach. This change refactors completion to add candidates to search
queue instead and only call deepSearch once at the end.

Danish Dua e94ab72881 internal/lsp/source/completion: improve import suggestion labels
This change improves the labels for import suggestions to only show the
last part of the path. Since VSCode fuzzy searches for labels in text
edit, we now return only the last part of path as text edit instead of
replacing the full import path. Just changing label while returning full
path leads to bad user experience.

I have no idea what I did to trigger this, but I got a panic in this

this code defensive, without fully understanding the cause.

Here's the panic:

Heschi Kreinick 6a8222ee25 gopls/doc: generate settings JSON, docs
gopls has many settings. We want to automatically generate
documentation, and we want to allow clients to perform their own
validation if they so desire.

Using all three of AST, type information, and reflection, generate a
JSON description of the settings and their default values. Add a gopls
command that prints it. Add a documentation generator that uses it to
write settings.md.

I assumed that everything not explicitly documented was experimental,
and moved it into that section. I also moved expandWorkspaceToModule to
experimental; I hope it's not long for this world, personally.

Along the way, rename many fields, make the enum matching case
insensitive, and add a stringer call so that the defaults print nicely.

Fixes golang/go#33544.

Completion is slowly becoming a large part of internal/lsp/source and it
makes sense to move to its own seperate package inside source to make
future refactors easier. As a part of this change, any unexported
members from source required by completion are now exported. Util
functions only required by completion are moved from
internal/lsp/source/util.go to internal/lsp/source/completion/util.go.
