Update to v2.4.0, which brings optimizations and minor improvements.
Upstream fixed the issue with word breaks in v2.3.0,
released back in July 2021. For more, see:
https://github.com/mvdan/xurls/issues/49
In short, ASCII TLDs now require a word break in Relaxed again.
Note that non-ASCII TLDs don't require one, as that just breaks them.
So, in that sense, this is making non-ASCII TLDs work in gopls again.
Plus, we avoid wasting CPU cycles at init time by rebuilding the regexp.

Before this change, newWorkspace would fall back to other workspace
types if there was an error parsing go.work files, or one of the
workspace modules did not exist. Instead, in those cases, newWorkspace
now successfully builds a *workspace with an error set.
This respects the user's intent when working with a go.work file so that
gopls can surface a diagnostic with the error.

Add a new subdirectory 'signature-fuzzer' to the x/tools/cmd
directory, with contents:
internal/fuzz-generator Guts of the signature fuzzer
fuzz-driver Simple driver for the fuzzer
fuzz-runner Test harness for doing iterative fuzzing
This set of tools is primarily of interest to compiler developers as
opposed to end users. The fuzzer generates random Go code with
"interesting" randomly chosen function signatures (random numbers of
parameters of randomly generated types), then emits code to call these
random functions with known inputs, as well as code that checks to
make sure parameter values were passed correctly and that returns
worked. The generator tries to include odd scenarios and corner cases
(e.g. reflect calls, recursion, blank params, zero sized types, etc)
so as to explore all the nooks and crannies of the compiler.
This fuzzer was used during the bringup of the new register ABI (as
part of Go 1.17) to identify odd corner cases and flush out bugs. It
may be useful in the future if we have to support new ABI versions or
bring up register ABIs on new architectures.
See the README.md for more details.

These arrays can be quite large, reducing the size of them
save lot of space reducing cache usage and file size.

This will make GOWORK value appear in the gopls log
when initializing the workspace. This CL does not include
GOWORK in `environmentVariables` (in view.go) (yet).

The function printAcceptedFuzzType was renamed to
formatAcceptedFuzzType after PS6 of CL 374495, but the rename was
missed in one spot and didn't get caught by TryBots.

This CL adds a quickfix CodeAction that detects "missing method"
compiler errors and suggests adding method stubs to the concrete
type that would implement the interface. There are many ways that
a user might indicate a concrete type is meant to be used as an interface.
This PR detects two types of those errors: variable declaration and function returns.
For variable declarations, things like the following should be detected:
1. var _ SomeInterface = SomeType{}
2. var _ = SomeInterface(SomeType{})
3. var _ SomeInterface = (*SomeType)(nil)
For function returns, the following example is the primary detection:
func newIface() SomeInterface {
return &SomeType{}
}
More detections can be added in the future of course.

This will validate that first letter after FuzzFoo() should be uppercase
Also, following validation will be performed for f.Fuzz() calls :
1. f.Fuzz() should call a function and it should be of type (*testing.F).Fuzz().
2. The called function in f.Fuzz(func(){}) should not return result.
3. First argument of func() should be of type *testing.T
4. Second argument onwards should be of type []byte, string, bool, byte,
rune, float32, float64, int, int8, int16, int32, int64, uint, uint8, uint16,
uint32, uint64

When a prepare rename request is issued on an package
import with no alias, the range returned by prepare
rename has length 0. This by itself does not provide
enough information to the client about what the original
name of the import statement. By returning a range and
a placeholder, this allows the client to correctly present
the information about what is being renamed to the user.

LinkifyText should not generate links to global declarations for
identifiers that are type parameters.
Because the syntactic resolver does not record the declaration for type
parameters declared in the method receiver (see
https://golang.org/issue/50956) a name lookup is used as a workaround.
This is fine here because it is only applied to undeclared indentifiers
and LinkifyText is only ever called on a single declaration at a time,
not on a full AST.
