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.

This change permits starting gopls without a root URI or any workspace
folders. If no view is found for an opened file, we try to create a new
view based on the module root of that file. In GOPATH mode, we just
use the directory containing the file.
I wrote a regtest for this by adding a new configuration that gets
propagated to the sandbox. I'm not sure if this is the best way to do
that, so I'll let Rob advise.

The gopls workspace environment defaults to the process environment in
which gopls was started. This means that when switching environments,
gopls can potentially get a different environment when connecting as an
editor sidecar from when forwarding requests to the daemon.
To (hopefully mostly) mitigate this pain point, inject the Go
environment when forwarding the 'initialize' request, which contains
InitializationOptions containing the 'env' configuration. We could go
further and send the entire os.Environ(), but that seems problematic
both in its unbounded nature, and because in many cases the user may not
actually want to send their process env over the wire. Gopls behavior
should *mostly* be parameterized by gopls binary and Go env, and after
this change these should match for forwarder and daemon.
For go1.15, Explicitly set the GOMODCACHE environment variable in the
regtest sandbox. Without this, regtests were failing in the forwarded
environment because they implicitly shared a module cache.

-remote.debug: -debug for the auto-started daemon
-remote.logfile: -logfile for the auto-started daemon
As part of this change, no longer enable debugging the daemon by
default.
Notably none of this configuration affects serving, so modifying this
configuration has been chosen not to change the path to the automatic
daemon. In other words, this configuration has effect only for the
forwarder process that starts the daemon: all others will connect to the
daemon and inherit whatever configuration it had at startup. This should
be OK, because in the common case this configuration should be static
across all clients (e.g., many Vim sessions all sharing the same
.vimrc).
Exposing this configuration made the signature of lsprpc.NewForwarder

variadic options pattern for initializing both the Forwarder and
StreamServer, the latter just for consistency with the Forwarder.

When the gopls daemon is automatically managed (-remote=auto), it will
be started by one of the forwarder gopls processes that was in turn
started by the editor. By default, this puts it in the same process
group as the forwarder gopls.
Some editors (at least Vim) send SIGTERM to the process groups of
sidecar processes when exiting. This can cause the gopls daemon to
terminate, thereby losing state.
Rather than ignore SIGTERM (which is bound to be editor dependent
anyway), let's just put the gopls daemon in a separate session.

This allows us to register a telemetry exporter that works with mulitple active
debug instances.
It also means we don't have to store the debug information in our other objects.

When using the experimental feature where gopls runs as deamon, the
remote is spawned with debug enabled. It currently exposes the debug
interface to all network interfaces. This should be configurable in
the future, but until then we should at least keep it on the
localhost interface.
This change starts the debug on the local interface instead of all.

By running the client connection before the forwarder-remote handshake
completes, we introduce a race in the TestDebugInfoLifecycle: the editor
may connect and initialize before the handshake, and assertions on the
debug state fail.
Requiring that the handshake complete before running the client
connection fixes this flakiness. It also seems like a good thing to
have the handshake complete before proceeding with any LSP.

It would be bad behavior if a gopls forwarder process started the gopls
daemon and it stuck around indefinitely. Add an idle timeout by default
for the gopls daemon.

Gopls behavior on disconnection is currently somewhat undefined, because
it hasn't mattered when there was a single gopls session per binary
invocation. With golang/go#34111, this changes.
Checks are added to ensure clients and sessions are cleaned up when an LSP
connection closes. Also, normal client disconnection is differentiated
with the jsonrpc2.ErrDisconnected value.

Most users will not want to manage their own gopls instance, but may
still want to benefit from using a shared instance.
This CL adds support for an 'auto' network type that can be encoded in
the -remote flag similarly to UDS (i.e. -remote="auto;uniqueid"). In
this mode, the actual remote address will be resolved automatically
based on the executing environment and unique identifier, and the remote
server will be started if it isn't already running.

In the ideal future, users will have one or more gopls instances, each
serving potentially many LSP clients. In order to have any hope of
navigating this web, clients and servers must know about eachother.
To allow for such an exchange of information, this CL adds an additional
handler layer to the serving configured in the lsprpc package. For now,
forwarders just use this layer to execute a handshake with the LSP
server, communicating the location of their logs and debug addresses.
