TestInput is fiendishly slow and memory-hungry. Breaking it into
subtests reveals that the vast majority of that cost can be attributed
to a single test case: "testdata/a_test.go".
Update the address-space-based skip to skip only that one input, skip
it under the race detector (it is timing out on the new
"linux-amd64-longtest-race" builder), and run the remaining inputs in
parallel (to reduce test latency now that we've better identified the
culprit).

For now, they must continue to refer to the same instance,

there will be no need for a global FileSet and each Package

The only explanation I can think of for the failure in
https://go.dev/issue/49387#issuecomment-1303979877 is that maybe the
idle timeout started as soon as conn1 was closed, without waiting for
conn2 to be closed. That might be possible if the connection returned
by Dial was still in the server's accept queue, but never actually
accepted.
To eliminate that possibility, we can send an RPC on that connection
and wait for a response, as we already do with conn1. Since the conn1
RPC succeeded, we know that the connection is non-idle, conn2 should
be accepted, and the request on conn2 should succeed unconditionally.

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

Prior to this CL we already shut down a jsonrpc2_v2.Conn when its
Reader breaks, which we expect to be the common shutdown path.
However, with certain kinds of connections (notably those over
stdin+stdout), it is possible for the Writer side to fail while
the Reader remains working.
If the Writer has failed, we have no way to return the required
Response messages for incoming calls, nor to write new Request
messages of our own. Since we have no way to return a response,
we will now mark those incoming calls as canceled.
However, even if the Writer has failed we may still be able to read
the responses for any outgoing calls that are already in flight. When
our in-flight calls complete, we could in theory even continue to
process Notification messages from the Reader; however, those are
unlikely to be useful with half the connection broken. It seems more
helpful — and less surprising — to go ahead and shut down the
connection completely when it becomes idle.
This is a redo of CL 446315, with additional fixes for bugs exposed on
the -race builders and some extra code cleanup from the process of
diagnosing those bugs.

Simplify the api-diff implementation to use `go run` and cmp.Diff. The
latter is more maintainable and produces more readable output, due to
supporting line diffs for multi-line strings.

Prior to this CL we already shut down a jsonrpc2_v2.Conn when its
Reader breaks, which we expect to be the common shutdown path.
However, with certain kinds of connections (notably those over
stdin+stdout), it is possible for the Writer side to fail while
the Reader remains working.
If the Writer has failed, we have no way to return the required
Response messages for incoming calls, nor to write new Request
messages of our own. Since we have no way to return a response,
we will now mark those incoming calls as canceled.
However, even if the Writer has failed we may still be able to read
the responses for any outgoing calls that are already in flight. When
our in-flight calls complete, we could in theory even continue to
process Notification messages from the Reader; however, those are
unlikely to be useful with half the connection broken. It seems more
helpful — and less surprising — to go ahead and shut down the
connection completely when it becomes idle.

Memory profiles show heavy allocation for the stack
and the function closure of FindDeclAndField.
This change moves both outside the loop, reducing
this function's fraction of allocation from 6.7%
before to 5.0% after, and reducing running time
by 3-7% on these benchmarks.

Serve had a misleading name and signature: it did not actually block

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.

Also implement and use the Shutdown method, which was mentioned in a
doc comment in CL 292169 but not actually present at that time.
With proper synchronization, we don't need heuristics to determine
whether an error is due to a connection or listener being closed.
We know whether we have called Close (and why), and we can assume
that if we have called Close then that is probably the reason for
any returned error.

Prior to this CL, (*Server).run only filters out inactive connections
when it accepts a new connection. If existing connections complete,
their associated resources can't be garbage-collected until either the
next connection is accepted or the Listener is closed.
This change moves the open-connection accounting to an explicit hook
passed to newConnection, eliminating the need to call Wait entirely.

This change fixes the semantics of Close to actually wait for
in-flight requests before closing the ReadWriteCloser. (Previously,
the Close method closed the ReadWriteCloser immediately, which I
suspect is what led to many of the failures observed in
golang/go#49387 and golang/go#46520.)
It achieves this by explicitly tracking the number of in-flight
requests, including requests with pending async responses, and
explicitly rejecting new Call requests (while keeping the read loop
open!) once Close has begun.
To make it easier for me to reason about the request lifetimes, I
reduced the number of long-lived goroutines from three to just one
(the Read loop), with an additional Handler goroutine that runs only
while the Handler queue is non-empty. Now, it is clearer (I hope!)
that the number of in-flight async requests strictly decreases
after Close has begun, even though the Read goroutine continues
to read requests (and, importantly, responses) and to forward
Notifications to the preempter.

In a type such as
type X interface { m() []*interface { X } }
the traversal never encounters the named type X in the result of m
since Interface.Methods expands it to a set of methods, one that
includes m, causing the traversal to get stuck.
This change uses an alternative, shallow hash function on the types
of interface methods to avoid the possibility of getting stuck in
such a cycle.
(An earlier draft used a stack of interface types to detect cycles,
but the logic of caching made this approach quite tricky.)

When the default filter glob changed to **/node_modules,
the performance of BenchmarkWorkspaceSymbols was observed
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
running.)
This change removes the unnecessary ^.* prefix from the
generated regular expression. Really the regexp package
ought to do this.
Also, minor cleanups and tweaks to the surrounding code.
