This fixes a bunch of fmt.Errorf calls to use %w rather than %v when wrapping
an error with additional context.

ed308ab3e7 internal/lsp: avoid showing no-GOPATH-nor-module message so much
If the user's workspace is neither in GOPATH nor a module, and there
are errors in their code, send a message (with ShowMessage) only on
the first load, or when the configuration changes. The previous
behavior sent the message more frequently.

There is a regtest, and two new Expectations for when the fake
editor sees (or does not see) a ShowMessage notification.

542909fd99 internal/lsp/cmd: partially revert "add a flag to disable telemetry"
This reverts commit 17a19b5fe7. The revert
is partial because that change also added the -short flag when running
govim tests, which we preserve as without this the tests often time-out
(and I don't want to increase our test timeout right now).

Reason for revert: telemetry races have been fixed in https://golang.org/cl/226317

2658dc0cad internal/lsp: add a regtest for formatting one-line files
Issue https://github.com/golang/go/issues/36824 complained about
legal go code (e.g., 'package a; func f() {}') that was mishandled
(by being rewritten just as 'package a'). This bug seems to have been
partially fixed, as certified by the new regtests. The comment on
OneLineImports36824 says that the bug would be fixed if gopls
formatted the file before fixing the imports, but it doesn't.

f26c0dd982 internal/lsp/source: improve unimported package member ranking
Untyped members from unimported packages are scored the same as typed
members from unimported packages. We depended on the unimported
package relevance to rank the probably-more-relevant typed members
higher. However, there are some unrelated score penalties that can
only be applied to typed candidates, so the untyped candidates ended
up being ranked higher. Fix by increasing the relevance coefficient so
the relevance score overpowers other less important scoring
adjustments.

Fixes golang/go#38104.

4b814e0613 internal/event: re-use ocagent exporters
This attempts to detect a Connect call with the same configuration and return
the same exporter.
This mostly affects tests where we end up starting a new ticking go-routine per
test, even though they all have the same configuration. It was noticable that
a goroutine dump of a test would have a very large number of go routines that
were just ticking exporters, making it very hard to see the real work.

b8428586f4 internal/lsp: handle hover documentation for package declarations
We had previously not been generating documentation on hover for
package declarations or import specs. We do this by adding a few special
cases, since package declarations don't appear in type information.

Throughout, we make the assumption that only one file in a package will
have the documentation for the package. go/doc just appends
documentation as it sees it. We may be able to do better by checking for
a "Package ..." but that still is not guaranteed. Not sure what the
right approach is, so this assumption may be the best option.

0c9eba77bc internal/lsp/regtest: add a OnceMet combinator for Expectations
A common problem when writing regtests is that if you have an error in
your expectations, you must wait until the regtest times out to see what
went wrong.

With the integration of additional progress reporting in the LSP server,
we know when diagnostic work should have been completed, and we should
be able to fail tests early once we know that our diagnostic
expectations will never be met.

This CL adds a new OnceMet Expectation, which combines two expecations:
the first is a precondition that must be met before checking the second.
The second is an arbitrary expectation, but is translated as follows:
once the precondition is met, the second condition is checked and any
Unmet verdicts are translated into Unmeetable.

46dc332f25 internal/lsp: instrument work done reporting to use in regtests
In order for regtests to wait until file diagnostics are complete,
instrument diagnostics with verbose WorkDone reporting. In order for
this to be granular enough for use, the modification source needed to be
threaded through to the didModifyFiles function (which is where the
diagnostic goroutine is spun off).

A new expectation is added: CompletedWork, to allow specifying that a
specific work item has been completed. The problem with using
NoOutstandingWork was that it required a continuous chain of work to
prevent the regtest from succeeding when the bug was present, meaning
that by the time we have sent the didChange notification successfully
the server must have started work on its behalf. This was inherently
racy, and too tricky to get right.

Additionally, a couple bugs are fixed:
 - EmptyDiagnostics is corrected to account for the case where we have
   received zero diagnostics for a given file.
 - A deadlock is fixed in Await when expectations are immediately met.

479cc23432 internal/jsonrpc2: fix goroutine leak when listener is closed
When jsonrpc2.Serve times out or is cancelled, we leak the goroutine
that is accepting connections, because it is stuck trying to write its
error back to the doneListening channel.

Fix this by adding a context cancellation for the serve func, and
selecting on this context when writing the error.

f3a5411a4c internal/lsp: fix panic when trying to log an event
Formatting keys in labels can panic when a label is constructed with a nil
error. Avoid that by not passing the defective label to event.Log.

8463f397d0 internal/lsp/source: fix false positive "..." in completions
In cases like:

    var v interface{}
    fmt.Println(<>)

Completing to "v" would insert "v..." instead of "v". This was due to
a mixup where we were checking if the variadic type "[]interface{}"
was assignable to the candidate type "interface{}" instead of the
other way around.

Fixes golang/go#38652.

59e73619c7 internal/lsp: correctly handle type aliases when formatting
This change improves our approach to handling type aliases. Previously,
we were not fully qualifying the names in the AST, making the code
inserted in completions incorrect at times. Now, we clone the relevant
AST expr and qualify it. We also add handling for the return values of a
function, instead of just the parameters.

38a97e00a8 internal/lsp/regtest: track outstanding work using the progress API
In preparation for later changes, add support for tracking outstanding
work in the lsp regtests. This simply threads through progress
notifications and tracks their state in regtest.Env.state. A new
Expectation is added to assert that there is no outstanding work, but
this is as-yet unused.

A unit test is added for Env to check that we're handling work progress
reports correctly after Marshaling/Unmarshaling, since we're not yet
exercising this code path in actual regtests.

c81623a0cb internal/event: move event/core.Tag to event/label.Label
Also moves core.Key to label.Key, but leaves the implementations
behind for now.
After using for a while, the word Tag conveys slightly the wrong
concept, tagging implies the entire set of information, label maps
better to a single named piece of information.
A label is just a named key/value pair, it is not really tied to the
event package, separating it makes it much easier to understand the
public symbols of the event and core packages, and allows us to also
move the key implementations somewhere else, which otherwise dominate
the API.

The code for formatting function signatures is fairly confusing.
Factoring out an unexported signature type simplifies things a bit.
Hopefully we'll be able to pull out more formatting logic from the other
features. Ideally, I'd like to return to the separation between
internal/lsp/source and internal/lsp so that a formatting package can be
pulled out and used in internal/lsp.
