This CL fixes a several bugs in workspace invalidation:
- When invalidating the workspace due to a change in gopls.mod or
go.work files, we should not update the workspace if the change does
not parse. There was a comment to this effect, but it was not
properly implemented.
- Check go.work before gopls.mod, consistent with our intitial
workspace load.
- If we get an 'unchanged' change (such as a save) to go.work, don't
continue looking for gopls.mod.
A regression test that inadvertently relied on our mishandling of broken
go.work files is updated to have the correct syntax. A new regtest
expectation is added to assert on a clean workspace.

The 'go' command reads the main module's 'go.mod' file with the file
locked. If 'gopls' starts a 'go' command in the background that reads
the 'go.mod' file, there is a narrow window in which that read can
race with the test's ioutil.WriteFile.
This change retries the write (as a user would probably do), fixing
the test failure. However, I suspect that there may be a broader UX
issue here that it will mask: in order to actually avoid the race
without a locking error, something in the LSP protocol needs to be
synchronizing gopls-initiated reads with editor-initiated writes. The
test failure this fixes indicates that that synchronization seems not
to be happening.

In https://go.dev/issue/50879, we observe ECONNRESET errors from
'dial' in TestRedirect for various paths. That seems to imply that a
unique connection is being dialed for each path — but these
connections are all going through http.DefaultTransport, which has a
30-second keepalive, and the test takes well under that amount of time
to complete.
The only reason we would be dialing a connection per request would be
if the connection itself leaks — and, indeed, inspecting the test in
more detail it fails to close the response body.
I don't know why failing to close the response body would lead to
ECONNRESET errors, but at the very least fixing that issue should
reduce the number of 'dial' operations and thus the number of
platform-specific failure modes.

We care that gopls operations complete within a reasonable time.
However, what is “reasonable” depends strongly on the specifics of the
user and the hardware they are running on: a timeout that would be
perfectly reasonable on a high-powered user workstation with little
other load may be far too short on an overloaded and/or underpowered
CI builder.
This change adjusts the regtest runner to use the test deadline
instead of an arbitrary, flag-defined timeout; we expect the user or
system running the test to scale the test timeout appropriately to the
specific platform and system load.
When the testing package gains support for per-test timeouts
(golang/go#48157), this approach will automatically apply those
timeouts too.
If we decide that we also want to test specific performance and/or
latency targets, we can set up specific configurations for that (as
either aggressive per-test timeouts or benchmarks) in a followup
change.

As described in golang/go#50481, in the existing export data schema
blank type parameters do not have unique names, and therefore types with
multiple blank (receiver) type parameters cannot be correctly imported.
This CL implements the fix proposed in that issue, using the schema
<prefix>.$<index> as the exported name of a blank type parameter, where
<prefix> is the qualifying prefix and <index> is the index of the type
parameter in its type parameter list. The importer is backwards
compatible with the old schema: it will continue to import <prefix>._ as
long as there are not multiple blank type parameters.
I considered not making the exporter change simultaneously with the
importer change, so that we interleave the corresponding changes in the
standard library. However, that made it harder to test the importer, and
updating both seems unlikely to cause problems.

and change GetIndexExprData to an UnpackIndexExpr method, symmetric with
PackIndexExpr. With the IndexListExpr type, both UnpackIndexExpr and
PackIndexExpr can be moved to common.go.

We have inconsistent rendering of newlines in enums, as pointed out in
CL 314189 (that change edited the markdown directly, which won't work).

The fastfuzzy matcher is around 3x faster than the fuzzy matcher for
queries that need to search a large number of symbols, and has improved
scoring due to built-in knowledge about the structure of Go symbols.
Enable it in experimental builds of gopls, with plans to enable it by
default in the next release.

I'm not sure how to hit this in practice, since it appears that symbols
should only return errors with some type of corruption, but we should
keep going when searching for symbols in snapshot files.

Hook up the fastfuzzy symbol matcher to our fzf-style query parsing, for
consistency with the (slow) fuzzy matcher.
In the past I had wanted to implement this natively inside the
SymbolMatcher, but it is much simpler to keep using combinators. In the
common case we'll just be using fuzzy matching.

In the new SymbolMatcher, add an additional scoring feature that
considers whether the matching pattern streak is part of a whole-word
match. This differentiates matches of "foo" against "pkg.foo" and
"pkg.foobar".
