Enable to hover runes found in basic literals in various forms.
When a rune is found, the hover message provides a summary composed of a
printable version (if it exists) of the rune, its codepoint and its name.
Behaviour varies slightly depending on the basic literal: rune literals
always display the summary when hovered, string literals only display it
when an escaped rune sequence is found to avoid providing unnecessary
information, and finally number literals only when expressed as a
hexadecimal number whose size ranges from one to eight bytes.

This CL handles the panic in the sergi/go-diff library which has not
yet been resolved. We add an error return to the ComputeEdits function
and return an error if there is a panic. I'm not sure if this is the
best approach, but it does seem better than allowing the server to
crash.
A concern would be that the user wouldn't know why their code wasn't
being formatted, but hopefully they might look through the logs and
notice the error message. At least, other features would continue
working. The best fix will definitely be the fix for the panic, but that
is not yet available.
Threading through the error return was not pretty, but I thought it was
probably worth doing since it could be needed in other situations.

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.

source.Analyzer now has a field to indicate if its suggested fix needs

The gopls daemon had different default logging behavior than the sidecar
gopls: by default, the daemon was started with -logfile=auto.
Additionally, because most logs are reflected back to the forwarder, the
actual daemon logs have very little (if any) information.
This means that if you simply start gopls with -remote=auto, you'll get
a single logfile named /tmp/gopls-<pid>.log, which is mostly empty. This
is not a delightful experience.
Fix this via several improvements:
+ Log lifecycle events in the Daemon, to give the log a purpose.
+ Give the daemon a new default log location:
/tmp/gopls-daemon-<pid>.log.
+ Don't pass -logfile=auto to the daemon by default.

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

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.

definition.Run requires a nil check of opts before applying to avoid
panic, and test must be run with markdown enabled.
When running 'go test' without -run flag, connection.initialize() was
not called and there was no problem because the default value of
Options.PreferredContentFormat was Markdown.
In addition, currently using the same connection despite different
options, therefore make to use a different connection for different
options.

While experimenting with different static analysis on x/tools, I noticed
that there are many actionable diagnostics found by staticcheck. Fix the
ones that were not false positives.

This change adds support for passing a span to cmd/suggested_fix.go, originally it would just take the filename and apply all the fixes for that file. Now, it can also take just a span within that file and only apply the fixes relevant to that span.
The //@suggestedfix marker now contains an extra parameter to specify which type of codeaction is expected.

With #34111, we are forwarding the LSP from one gopls instance to
another. This exposed an asymmetry in our LSP dispatching: for both
ClientDispatcher and ServerDispatcher, we unmarshal to non-nil response
structs. This means that when forwarding the LSP, we translate empty
JSON responses (corresponding to nil values) into the non-nil zero
value.
This causes problems for some editors, as reported in #37570. Fix it by
instead unmarshaling to a pointer.
This is, of course, a somewhat dangerous change. I fixed the one NPE
that occurred in tests, and have done some mild manual testing. I
wouldn't be surprised if we discover more NPEs later on, but I still
think this is the right change to make.

This change appends to the pkg.go.dev link the version of the module that is being used. To get this functionality, go/packages.Package now contains a module field which gets populated from the "go list" call. This module field is then used to get the version of the module that we are linking to.
