Rob Findley 08f19738fa gopls/internal/regtest: only run in singleton mode
singleton mode is naturally less flaky and faster than forwarded mode,
and provides 98% of the coverage.

Regtests have started to time-out in some particularly slow
environments.  Rather than not be able to write more regtests, let's
first run only in singleton mode by default.

I'll set up Kokoro CI to run in all modes.

Rebecca Stambler 22683886a9 internal/lsp: fix go.mod creation without experimental workspace module
We were previously adding modules to the snapshot, even if they weren't
relevant without the workspace module mode. Now, check that the modules
are relevant before adding them.

Rob Findley 8445f4f065 internal/lsp: add experimental support for multi-phase diagnostics
An experimental new feature is added to run parsing and checking on
modified files immediately, and run analysis and diagnostics for
transitive dependencies only after debouncing. This feature is disabled
by default.

Also, some refactoring is done along the way:
 + Clean up diagnostic functions a bit using a report collection type.
 + Factor out parsing diagnostics in options.go.

Rebecca Stambler 0d28ed0cbe gopls: add a test that mirrors govim's -mod=readonly test
This isn't strictly necessary, but we've broken it a number of times,
and it's easier to have a regtest for it. When golang/go#41437 is resolved, we
might consider making this a -mod=mod test or something.

Also, added a wrapper for RunGoCommand.

Bryan C. Mills 41c411d754 internal/lsp/testdata: remove diagnostic from percent package
The percent package has an invalid import path and a disallowed
character in a source file. In CL 258298, I am changing cmd/go to
diagnose invalid import paths during loading (instead of during
missing-import resolution), and as a result 'go list' will no longer
attempt to load or enumerate the source files for that package.

It is important that gopls and 'go list' not crash when attempting to
load a package with an invalid path, but gopls should not assume that
'go list' will produce anything more than an error for it.

There was a race condition setting the metadata--we were reusing old

always override metadata.

Also, disabled the TestUseGoplsMod test -- there seems to be an issue
with it. Will discuss this offline in the AM.

Lock around log access in regtests. This flake was relatively rare in
regtests because of the serial nature of our jsonrpc2 implementation,
but was nonetheless racy.

Rebecca Stambler 5d1fdd8fa3 internal/lsp: allow multiple go.mod files in a view
This change allows a view to have multiple go.mod files associated
with it. This doesn't actually make any changes in internal/lsp/cache
with regards to the view's modURI, but it does do the necessary plumbing
in the client packages.

The next CL will delete modURI.

Heschi Kreinick e8435508c6 internal/lsp: run marker tests in multi-module mode
Multi-module mode works rather differently than module mode, so ideally
we should have good test coverage for it. We can get a lot for a little
by running the marker tests as a module in a multi-module workspace. To
do that, we can move everything one directory lower, and use the
original directory as the root of the workspace.

The mechanics of setting it up are a little distasteful but not too bad.
We prepend a directory to all the paths in the packagestest.Module, and
after Export, move the created go.mod down into that directory. The only
other change is to find the golden files in the right place.

Command line tests use URIs everywhere, and it was too annoying to fix
them, so I didn't bother. Unimported completion tests fail and are
skipped for the moment.

Heschi Kreinick 82fe25c375 gopls/doc: improve enum value documentation
Add a new field to the options JSON, EnumValues. Use it to automatically
generate the documentation for enums. Fix the displayed type to be
"enum" rather than the full-qualified Go type name.

To make this easy, I changed the various enum constants to be strings,
with values matching their configuration values. It may be possible to
automatically parse them in the future, but we can get to that later.

The documentation for hoverKind's private values is a little janky. I
didn't want to build a way to hide them. We can hardcode it if we really
care.
