6a72e3782c internal/lsp/fake: don't lock while calling formatting
While trying to be pragmatic, I simply locked the fake.Editor while
calling textDocument/formatting. This did indeed manifest later on as a
deadlock, so instead we release the lock but fail if the buffer version
changes while awaiting the formatting call.

ae9902aceb internal/lsp: remove the CallCanceller
This required changing the jsonrpc.Conn.Call signature to also return the
request ID so it can be cancelled.
The protocol package now declares the Call function which wrapps up
Conn.Call and then sends a cancel message if the context was
cancelled during the call.
There is a small chance that a context can be cancelled on a
request that has already completed, but it is safe to do so.

3bd20875a2 internal/lsp/cache: hide type errors if we fix up the AST
I was curious about why were logging errors during type-checking in
tests, and the answer turned out to be a bit more sinister than I
expected. We were getting type error messages without filepaths, so I
tried to reproduce it in the playground and wasn't able to. I realized
that these errors were coming from were coming from the "fixed" version
of the AST that we pass to the type checker.

Adding fake positions to our fake Cond statements trivially fixes the
logging issue, but it does nothing to handle the fact that the error
makes no sense to the user - because it applies to something that's not
in the source code. I figured we have two options: (1) skip type errors
for all packages with "fixed" ASTs, or (2) add something to the error
messages to indicate that the source code may not match. Starting with
(1) here, and if it becomes a problem, we can move to 2. All ASTs that
we fix have *ast.BadExpr in them, meaning that, by definition they have
parse errors which we will preferentially show those errors to users in
diagnostics (so I'm not sure how to test this).

4d14fc9c00 internal/lsp: add type error fixes to existing diagnostics
This change is the first step in handling golang/go#38136. Instead of
creating multiple diagnostic reports for type error analyzers, we add
suggested fixes to the existing reports. To match the analyzers for
FindAnalysisError, we add an ErrorMatch function to source.Analyzer.

This is not an ideal solution, but it was the best one I could come up
with without modifying the go/analysis API. analysisinternal could be
used for this purpose, but it seemed to complicated to be worth it, and
this is fairly simple. I think that go/analysis itself might need to be
extended for type error analyzers, but these temporary measures will
help us understand the kinds of features we need for type error
analyzers.

A follow-up CL might be to not add reports for type error analyzers
until the end of source.Diagnostic, which would remove the need for the
look-up.

8f5be0d382 internal/lsp/regtest: add functions to make diagnostic assertions easier
One of the tricky things about asserting on conditions in regtests is
the asynchronous nature of LSP. For example, as the LSP client we cannot
be sure when we've received all diagnostics for a given file.

Currently, regtests are implemented by awaiting specific diagnostic
expectations.  This means that if gopls generates diagnostics that do
not match those expectations, we can only time out the test.

Ideally, we would want to know that gopls is done generating all diagnostics
for the current file state. This is not possible without knowing the
status of diagnostics for. Barring this, we would want to know that
diagnostics are done for the current file version. Unfortunately, that
also is not possible, because a new version of file B can affect
diagnostics in file A.

So in lieu of this information, this CL exposes a few tools that can be
used to improve the experience of writing new regtests.

 - A new expectation is added: AnyDiagnosticAtCurrentVersion, that is
   satisfied if any diagnostics have been received for the current
   buffer version.
 - ExpectDiagnostics is added to Env, to help check whether the current
   diagnostics matches expectations.

0a46fa39b0 internal/lsp/source: propose loaded unimported package names first
When proposing unimported package members, we start with packages loaded
in-memory first, for three reasons: we know that they're fast, they're
fully typed, and they're probably pretty relevant. I hadn't bothered
doing that for package names, because the first two reasons aren't very
relevant. But the third still is -- loaded packages are a pretty good
approximation for in module scope, etc.

With this change we do package names the same as members, so relevance
should be about as good. Not perfect, but nobody's complained much yet.

Fair bit of copy-and-paste, but I don't want to extend the
getAllCandidates abstraction outside of the imports package yet.

Updates #38104.

3304cfb00f internal/lsp: temporarily disable type error analyzers by default
If we release gopls/v0.4.0 soon, we should keep these new analyzers off
by default. They were just merged, so they haven't been used enough to
be enabled, I think. We'll turn them on by default for gopls/v0.5.0.

Also, ended up creating a helper function to check if analysis has been
abled (which fixed a small bug in FindAnalysisError), and another helper
function to enable all analyses for testing purposes.

This change makes sure that we only rebuild the view once a new go.mod
file is saved, not just created. It also preserves the snapshot ID
number when the view is recreated so that diagnostic caching continues
to work as expected.

82bb89366a internal/lsp/cache: validate workspace path case
On case-insensitive file systems, the editor may send us a path that
works but doesn't match the actual file's case. Then when we run go
list, we'll get mismatching paths and everything will break.

We can't reliably fix this problem: tracking what case the editor
expects is too difficult to be worth it. Instead, check the workspace
path and bail if it's mismatched.

Possibly we should also check files on DidOpen or such, but we can start
with this.
