579903b3ad internal/lsp: add mapper for go.mod files
This change adds a protocol.ColumnMapper when parsing go.mod files. This will prevent us from having to worry about line and column offsets, specifically when converting from the x/mod/modfile position to a span.Span.

3be912efc3 internal/lsp/protocol: support nonstandard requests
Support arbitrary client->server requests in the generated code. This is
primitive, with no strong typing, but should be good enough for simple
requests. We can do something fancier later if we want.

d31a08c2ed internal/lsp/source: improve completion support for args to builtins
We now understand what "kind" of type is expected when using various
builtins. For example, when completing "close(<>)" we prefer channels,
and when completing "delete(<>)" we prefer maps.

I also added some code to infer the expected type for the second
argument to "delete()" and for the args to "copy()":

delete(map[someType]int{}, <>) // expect "someType"

copy([]int{}, <>) // expect "[]int"
copy(<>, []int{}) // expect "[]int"

And I marked "new()" as expected a type name, and it infers the type
name properly:

var _ *int = new(<>) // expected type at "<>" is "int"

Fixes golang/go#36326.

544dc8ea2d internal/lsp: change go1.14 check to be more lenient
This change adds the -e flag to ensure that we get the release tags when we are checking if the go version is at least 1.14. This also adjusts the check to be more lenient when it comes to processing the output of the version check.

This also fixes another issue where if the version is not 1.14 we were publishing empty diagnostics for an empty uri. This arose because we did not check if there was a valid go.mod file before we published the reports.

533f309ed4 internal/lsp: reload workspace package metadata on demand
This change removes functions from the snapshot that return package IDs.
We prefer PackageHandles, since getting PackageHandles in a granular
fashion is not effective and causes us to spawn many `go list`
processes. By only ever returning PackageHandles, we can batch metadata
reloads for workspace packages. This enables us to add a check to
confirm that the snapshot is in a good state before returning important
data, like reverse dependencies and workspace package handles.

Additionally, the fuzzyMatching and caseSensitive boolean flags are

of matcher that is used for completion. Other requests (notably
workspaceSymbols) may need to use a matcher in the future.

6316571e2c internal/lsp: don't require type-checking for formatting
We had previously required a type-checked package for formatting
requests, in order to determine if the package contained any parse
errors. We can get this information directly from the ParseGoHandle, so
there is no need to check the package. This will prevent `go list`
errors from making their way into formatting requests, for which a `go
list` really is not needed.

a222fb47e2 internal/lsp/source: don't downrank builtin constant completions
We downrank untyped constant candidates so that we prefer candidates
whose type matches exactly. However, this was causing builtin
constants like "true" to be outranked by candidates that fuzzily match
"true". Fix by not downranking builtin constants.

Fixes golang/go#36363.

7201abb308 internal/lsp: parallelize initial workspace load
The initial workspace load was happening when a view was created, in serial.
It should really just be kicked off in a separate goroutine once we create a
new view. Implementing this change required some other significant changes,
particularly the additional work being done by the WorkspacePackageIDs
method.

Some other changes had to be made while debugging. In particular, the
modification to the circular dependencies test was a consequence of
golang/go#36265.

6de373a276 internal/lsp: fix minor issues in diagnostic caching
There were a few cases that we were missing when caching diagnostics.
The first was caching empty diagnostics from the initial workspace load,
so we were resending old empty diagnostics. The second missing case was
resending diagnostics for the same version of a file.

Fixes golang/go#36340.

Also, minor bug fixes: add a missing mutex, and use a lower-than-usual

In the module implementation specifically, try to avoid scanning if the

module dependencies before the whole cache.

3f7dfa39cf internal/lsp: sort by label after score
I want to stop sorting unimported completions. We still want to show
users something reasonable, so use label as a tiebreaker for score in
the higher level completion function.

To maintain the current sorting, we need to adjust scores by search
depth (height?) for lexical completions. A few tests are really ties,
and need sorting in the test case.

50c778fb86 internal/imports: redesign scan API
We have multiple use cases for scanning: goimports, import completion,
and unimported completions. All three need slightly different features,
and the latter have very different performance considerations. Scanning
everything all at once and returning it was not good enough for them.

Instead, design the API as a series of callbacks for each
directory/package: first we discover its existence, then we load its
package name, then we load its exports. At each step the caller can
choose whether to proceed with the package. Import completion can stop
before loading exports, goimports can apply its directory name
heuristics, and in the future we'll be able to stop the scan short once
we've found all the results we want for completions.

I don't intend any significant changes here but there may be some little
ones around the edges.

fd66c7521c internal/lsp/source: don't get unnecessary unimported completions
Unimported completions are always low-priority. If the user already
has 100 completion options, the unimported ones are probably not useful.
There's no point in calculating any of them.

Also, only do unimported completions for package members when they're
enabled. Oops.

call to packages.Load. Some adjustments from CL 212102 were split out
into this CL.
