Update golang.org/x dependencies to their latest tagged versions.
Once this CL is submitted, and post-submit testing succeeds on all
first-class ports across all supported Go versions, this repository
will be tagged with its next minor version.

I felt a bit confused on my first reading of the docs for using `go work`.
It wasn't clear to me if the `tools` argument in `go work use tools tools/gopls` was an alias or a directory name, so I thought this might make it very clear to understand for first time users.

When awaiting diagnostics, we should almost always wrap expectations in
a OnceMet(precondition, ...), so that tests do not hang indefinitely if
the diagnostic pass completes and the expectations are still not met.
Before this change, the user must be careful to pass in the correct
precondition (or combination of preconditions), else they may be
susceptible to races.
This change adds an AllOf combinator, and uses it to define a new
DoneDiagnosingChanges expectation that waits for all anticipated
diagnostic passes to complete. This should fix the race in
TestUnknownRevision.
We should apply a similar transformation throughout the regression test
suites. To make this easier, add a shorter AfterChange helper that
implements the common pattern.

This change adds an internal API for marshalling and
unmarshalling a types.Package to "shallow" export data,
which does not index packages other than the main one.
The import function accepts a function that loads symbols

indirect dependencies).
The CL includes a test that the entire standard

Also:
- break dependency on go/ast.
- narrow the name and type of qualifiedObject.
- add (test) dependency on errgroup, and tidy go.mod.

Also make (*Connection).Close safe to call from Bind.
A jsonrpc2_v2.Server has no good way to report an error from Bind.
If the Server saves the error to return from its own Wait method, that
might not ever actually happen: Wait waits for in-flight connections
to complete, but if some existing connection stays up then Wait will
not return.
If the Server goes ahead with establishing the connection and installs
its own Handler, that Handler needs to decide whether to serve the
error from Bind or something more opaque, and at that point Bind may
as well return a handler that makes that choice more precisely.
If the Server merely logs the error and closes the Connection, then
the Bind method itself may as well do that directly too.
It seems to me that the only winning move is not to play. Only Bind is
in a position to decide how to handle its errors appropriately, so it
should not return them to the Server.

With proper synchronization, we don't need heuristics to determine

When the default filter glob changed to **/node_modules,

to degrade by an astonishing 20%.
(CPU profiles of the benchmark reported that the Disallow
functions percentage had increased only slightly, but these
measures are misleading since the benchmark has a very
CPU-intensive set-up step, so all the percentages are
quotients of this figure, masking their relative importance
to the small region during which the benchmark timer is

Previously, the disaster logic in the new diff implementation
would "encrypt" the before/after files using a monoalphabetic
substitution, which has been insecure since the 9th century.
Instead, save plain text, in file with mode 0600, and invite
the user to audit the file before sharing it with us.
Also, separate the two files using a NUL byte, not a newline,
which is highly ambiguous.
Also, in the JSON diff stats writer:
- print a warning if we can't create the log file.
(The previous code was subtle--it stored a nil *os.File in
an io.Writer, which caused Writes to fail with an error,
in effect, silently.)
- Don't hold the mutex around the write operation.
- Fix minor off-by-one error (re: 15)
- Crash if JSON encoding fails; it "can't happen".

This is the first in a series of CLs implementing the new stub
generator. The code is intended to reproduce exactly the current
state of the generated code.
This CL has the final file layout, but primarily consists
of the parsing of the specification.
The LSP maintainers now provide a .json file describing the messages and
types used in the protocol. The new code in this CL, written in Go,
parses this file and generates Go definitions.
The tests need to be run by hand because the metaModel.json file is not
available to the presubmit tests.

When a module contains multiple vulnerabilities, previously gopls published
one diagnostic message for each vulnerability. This change modifies this
behavior to publish only one vuln diagnostic for each module. This will
make the PROBLEMS panel more concise and readable. However, the information
about each vulnerability finding is useful, so we supplement this diagnostics
by sending a hover message in the module require line. An added benefit
of this approach is that, unlike the Diagnostics, VS Code supports rich
text rendering for Hover messages. So we can use markdown to add links and
necessary highlighting.
Before this change, go.mod require hover messages (e.g. go mod why result)
were associated only with the module path part, excluding the version string
part. But for vulnerability information hover message, I think it is better
to be applied to the entire module require line (both module path & version)
because they are information about the specific module/version. Currently
LSP hover returns only one hover, so we cannot use this different range only
to the vulnerability information hover. Thus, one side effect of this change
is that the module info hover message will be also shown to the version
part of each require statement.

Update golang.org/x dependencies to their latest tagged versions.
Once this CL is submitted, and post-submit testing succeeds on all
first-class ports across all supported Go versions, this repository
will be tagged with its next minor version.

We need to search intermediate test variants to find all imports of a
renamed package, but were missing them because we only considered
"active packages". Fix this by building up the set of renamed packages
based on metadata alone: it is unnecessary and potentially too costly to
request all (typechecked) known packages, when we only need access to
the metadata graph to determine which packages must be renamed.
In doing so, it becomes possible that we produce duplicate edits by
renaming through a test variant. Avoid this by keeping track of import
path changes that we have already processed.
While at it, add a few more checks for package renaming:
- check for valid identifiers
- disallow renaming x_test packages
- disallow renaming to x_test packages
Also refactor package renaming slightly to pass around an edit map. This
fixes a bug where nested import paths were not renamed in the original
renaming package.
Fix some testing bugs that were exercised by new tests.

An import path is not the same as a package path.
For example, the declaration:
import "example.com/foo"
may load a package whose PkgPath() is "vendor/example.com/foo".
There was a comment hinting at this in load.go.
This change introduces the concept of ImportPath as a
distinct type from PackagePath, and documents clearly
throughout the relevant APIs which one is expected.
Notes:
- Metadata.PkgPath is consistently set from the PackagePath,
not sometimes (when a root) from PackagePath and sometimes (when
indirectly loaded) from an arbitrary ImportPath that resolves to it.
I expect this means some packages will now (correctly)
appear to be called "vendor/example.com/foo"
in the user interface where previously the vendor prefix was omitted.
- Metadata.Deps is gone.
- Metadata.Imports is a new map from ImportPath to ID.
- Metadata.MissingDeps is now a set of ImportPath.
- the package loading key is now based on a hash of
unique imports. (Duplicates would cancel out.)
- The ImporterFunc no longer needs the guesswork of
resolveImportPath, since 'go list' already told us
the correct answer.
- Package.GetImport is renamed DirectDep(packagePath)
to avoid the suggestion that it accepts an ImportPath.
- Package.ResolveImportPath is the analogous method
for import paths. Most clients seem to want this.

Since we removed the 'recover' in analysis, which swept crash
bugs under the rug, we've seen a large number of crashes on
the builders in which an analyzer crashes while trying
to use the result of another analyzer (e.g. the inspector)
on the same package. Logging shows that the "same" package
is in fact a stale version of the same package.
The root cause is that the key for the analysis cache
is the analyzer name paired with the "recipe" for the
package. However, analysis is not content with an equivalent
package: identity matters for ast.Nodes, types.Objects, etc.
This change attemps to fix the problem by, in effect, using
the identity (not the recipe) of the package as part of the key.
It is materialized by adding a store of promises to the pkg,
and then using the analysis name as the key within this store.

Unlike other calls of qualified functions, the type of certain functions
in the unsafe package (namely Slice, Add) is not constant, and cannot be
determined by the types.Func being called. Update Finder.expr to
pre-emptively handle calls to functions in the unsafe package, similarly
to how it handles other builtins.

We now understand the longstanding race causing panics in gopls analysis
(the cache key for analysis handles is not correct, and can lead to
cache hits for analysis of stale packages).
It will take a little while to redesign our analysis caching, the
simplest solution being to hang analysis results off of the actual
package they are analyzing. In the meantime, suppress the panic as
before, to eliminate flakes.

This change moves the *pkg out of the actionHandle into
the actionResult. (In future we may not need to load the
package before creating the handle.) The actionResult
retains only the exported type information, to avoid keeping
the syntax trees (etc) live.
Also, perform object fact filtering once after the analysis pass,
instead of every time it is imported by another analysis.
Also, filter out unexported constants.
Also, log internal errors even when we don't bug.Reportf,
since errors merely returned by analysis are usually ignored,
making it harder to understand the analysis crashes.

Add support in gopls for working on "standalone main files", which are
Go source files that should be treated as standalone packages.
Standalone files are identified by a specific build tag, which may be
configured via the new standaloneTags setting. For example, it is common
to use the directive "//go:build ignore" to colocate standalone files
with other package files.
Specifically,
- add a new loadScope interface for use in snapshot.load, to add a bit
of type safety
- add a new standaloneTags setting to allow configuring the set of build
constraints that define standalone main files
- add an isStandaloneFile function that detects standalone files based
on build constraints
- implement the loading of standalone files, by querying go/packages for
the standalone file path
- rewrite getOrLoadIDsForURI, which had inconsistent behavior with
respect to error handling and the experimentalUseInvalidMetadata
setting
- update the WorkspaceSymbols handler to properly format
command-line-arguments packages
- add regression tests for LSP behavior with standalone files, and for
dynamic configuration of standalone files
