If -config=true, gopls vulncheck reads the package load
configuration JSON (build flags, env, tests, and later
maybe overlay info) from stdin.
And, add some logging to gopls/internal/vulncheck/command.go
that helps measuring the package loading overhead.

Instead of invoking the command through the LSP custom command,
call the vulncheck command hook directly. That reduces the extra
overhead of bringing up the full gopls server & package loading.
The vulncheck hook loads packages again any way, so the benefit
of running the check inside gopls's custom command framework
is not huge any more.
Still `gopls vulncheck` is useful - editors don't need to install
another binary for vulncheck feature, and it will output the
result in the format easier to handle than what `govulncheck`
currently offers.

Behaviour varies slightly depending on the basic literal: rune literals
always display the summary when hovered, string literals only display it

LSP (and gopls) support both full-file semantic token requests and
requests for just a range, typically roughly what's visible to the user.
It can be slow to produce the full set for a very large file, so
this code now responds with an error if the file is bigger than
100,000 bytes. After getting this error, vscode, at least,
will stop asking for full requests and use range requests.
Alternatively, server capabilities could say gopls never responds to
full-file requests, but doing that doesn't stop vscode from asking for
them. Another possibility would be to fix a time limit (like 8ms) for
how long to spend generating full-file semantic tokens. That's tricky
to get right, but one could instead generate an error when there
are more than 4,000 semantic tokens (on my laptop, that's about 8ms.)
Large files are unusual; a simple size limit seems adequate for now.

Fully switch to the new generated command API, and remove the old

+ Switch the command dispatch in internal/lsp/command.go to go through

signature.
+ Update commandHandler to use the new command signatures.
+ Fix some errors discovered in the command interface now that we're

+ Regenerate bindings.
+ Update all code lens and suggested fixes to new the new command
constructors.
+ Generate values in the command package to hold command names and the
full set of commands, so that they may be referenced by name.
+ Update any references to command names to use the command package.
+ Delete command metadata from the source package. Rename command.go to

+ Update lsp tests to execute commands directly rather than use an
internal API. This involved a bit of hackery to collect the edits.
+ Update document generation to use command metadata. Documenting the

compatibility for commands. Notably, the gopls.test and gopls.gc_details
signatures are preserved, as these are the two cases where we are aware
of LSP clients calling them directly, not from a code lens or

The Typescript source is still at version 3.16, but there are new
requests, more detailed client capabilities, and an attempt to be
more specific about ranges of number in the Typescript code.
Vscode defines types integer and uinteger (32-bit signed and unsigned),
so the Go code now uses int32 and uint32.
They've changed the use of TextDocument, so version information is sometimes
missing. cache/session.go:625 was changed correspondingly.
This CL also make CodeAction.Disabled into a pointer.
New requests or notifications:
DidCreateFiles, DidRenameFiles, DidDeleteFiles (notifications)
ShowDocument, WillCreateFiles,WillRenameFiles, WillDeleteFiles (request)
It's a lot of code; I've probably missed something.

This CL handles the panic in the sergi/go-diff library which has not
yet been resolved. We add an error return to the ComputeEdits function
and return an error if there is a panic. I'm not sure if this is the
best approach, but it does seem better than allowing the server to
crash.
A concern would be that the user wouldn't know why their code wasn't
being formatted, but hopefully they might look through the logs and
notice the error message. At least, other features would continue
working. The best fix will definitely be the fix for the panic, but that
is not yet available.
Threading through the error return was not pretty, but I thought it was
probably worth doing since it could be needed in other situations.

Combine the generation of the API json with the generation of the
documentation. This cuts out a step from the generation process, and
allows us to depend on third-party modules. Use litter to print a
composite literal instead of JSON text, which will diff and merge much
better.
The only real drawback is that you have to "go run" from the gopls
module to avoid adding the extra deps to tools.
Sorry about the copy and paste; there's relatively little actual code
change, just a bit in doMain and rewriteAPI.

Go 1.16 will set -mod=readonly to be the default behavior of the go
command. This CL changes gopls' behavior to be more in line with that.
The model we end up with is more explicit about managing the go.mod.
Previously, adding an import for a package in the module cache but not
in scope would succeed, but add a warning with a quick fix. Now, the
import will fail, again with a quick fix, and the project will not
compile until the require is added. It also means that the go.sum needs
to be in sync. Previously, the go command would update the temporary
go.sum if the user's was out of date, and then we would discard those
changes. Now, loads will fail until the go.sum is brought into sync,
either by `go mod tidy` or the new "update go.sum" command.
The go.sum requirements affect many regtests. I added a DumpGoSum
function to the environment, which prints the txtar format go.sum file
that needs to be added to the workspace. We'll need to keep them in
sync, unfortunately. We could update them on the fly, but that would
slow down the regression tests somewhat and potentially mess up the test
setup. So I'm not sure what to do exactly. Perhaps maintain them
out-of-line in a separate file that could be auto-updated? Dunno.
I also had to add go directives to go.mod files to keep old Go versions
happy.
Multi-module workspace mode currently doesn't create a go.sum file at
all and is held back to the old behavior until it does.

This updates fillstruct to work even when the struct is partially

Preserving comments appears to be very hard with the current ast

after exploring that path it seems like A Bad Idea.

The workspace symbol tests are not really resilient to changes and
did not generate/use golden files consistently. This made it really
tricky to switch the workspace symbols defaults.
To improve the workflow, consolidate the different kinds of tests into
one function, generate and use golden files, and require that all of the
workspace symbol queries appear in one file only. Also converted the
brittle workspace symbol regtest to a marker test.
