dbf5ce1eac internal/lsp/regtest: add expository package documentation
Update the regtest docstring to further explain how the package works,
and give a sense for why it exists.

12a1c85843 internal/lsp/regtest: rename and document some symbols
Minor cleanup for the regtest package:
 - EnvMode is renamed to Mode, because it's really a server mode and not
   directly related to the Env type.
 - Modes are better documented.

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.

9938a07982 internal/lsp: factor out progress reporting to a new WorkDone handle

preparation for using this API more widely, factor out the reporting API
from the current io.WriteCloser wrapper (workDoneWriter).

e9a00ec821 internal/lsp/cache: correctly split env vars
We were using strings.Split on env vars, which did bad stuff when the

gopls failed, just organize imports and the `go.mod` code lens stuff.

we map between these names correctly - handling the case of multiple

We still do not fully qualify unimported packages, and likely won't,
unless that's an issue for many users.

9ea0146da6 internal/jsonrpc2: remove jsonrpc2.ErrDisconnected
It was not very useful, it basically renamed io.EOF under some limited

Instead, the test now checks io.EOF directly, but also checks for
io.ErrClosedPipe which was also happening.
We also make sure we wrap errors rather than replacing them.
This prevents some weird random test failures due to races in the way they were

The standard event creators all have a matching test that returns true
if the the labels pattern matches the ones that would be built by the
creator.
Spans and logs already have a unique label pattern, other event types
required a special label marker.
This makes the system much more extensible, and also cleans up some
the API.

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.

504fe87a53 internal/lsp: add regtest for golang/go#38211
A few more updates to the regtest framework - add support for all
codeActions, not just organize imports. Also, return diagnostics from
env.Await to pass into code actions. Not sure if that's the correct way
to do it, so please let me know if there's a better way.

The test is for 1.14 only, since -modfile is only supported after 1.14.

Fixes golang/go#38211

4b6a508a9c internal/lsp: merge the in and out protocol logging functions
The special cases were all removed by the previous changes to jsonrpc2 messages.
The only difference now is the "Recieved" vs "Sending" text prefix, so we just paramaterize the common function with that instead.

cfa8b22178 go/packages/packagestest: do not walk packages and their test variants
Currently, where a package has a test variant, we end up walking the
non-_test.go files twice: once when walking the package itself, the
second time when walking the test variant. In the gopls tests, this
means we end up double-counting the number of symbols (via the @symbol
annotation) in a package.

Extend the existing expect_test.go to demonstrate the problem is fixed
(a test which fails when the fix is not in place)

434f7a8fef internal/jsonrpc2: add concrete types for Call, Notify and Response
The previous implementation was exposing the details of the wire format
and resulted in non idomatic go, detecting the presence of absence of
values in fields to deterimine the message type.
Now the messages are distinct types and we use type switches instead.
Request still exists as an interface to expose the shared behaviour of
Call and Notification, as this is the type accepted by handlers.
The set of messages is deliberately closed by using a private methods on the
interfaces.
