Now "implementations" supports finding interfaces implemented by the
specified concrete type. This is the inverse of what "implementations"
normally does. There isn't currently a better place in LSP to put this
functionality. The reverse lookup isn't an important feature for most
languages because types often must explicitly declare what interfaces
they implement.
An argument can be made that this functionality fits better into find-
references, but it is still a stretch. Plus, that would require
find-references to search all packages instead of just transitive
dependents.

Implementing this required fixing a broken assumption about text edits
in the editor: previously these edits were incrementally mutating the

Calling `panic` with a nil value is not possible to detect using
recover. The existing SSA-based "nilness" analyzer already inspects
relationships with simple comparisons to nil and the surrounding code,
pointing out mistakes where provably nil values are used incorrectly.
This change adds calls to `panic` with similarly provable nil values to
the circumstances to report.
The tests included cover common forms of the mistake. In particular, the
case where the value passed to panic was of type `error` (which is to
say, an interface type), the nil was not properly detected.
Incorporating unpacking the `ChangeInterface` SSA transformation allow
these cases to be detected. This change may have an impact on the cases
caught by existing nilness circumstances, but those only in that they
detect additional true problems. The difference is considered safe
because the ChangeInterface operation does not change the kind of value
or its degree of nilness.
In discussion on this change, it was also pointed out that type
assertions using the CommaOk form do not cause panics when asserting on
nil values. The analyzer previously reported a false positive "nil
dereference" error in those cases and that is now fixed.

Also, don't run in the 'Shared' execution mode by default: normal gopls

When running gopls against an automatically started remote instance, we
want the lifecycle of the remote to be detached from that of its
clients, so that it doesn't shut down while clients are still connected.
On the other hand, a gopls process can consume significant resources, so
we don't want it to remain when there are no more connected clients.
The jsonrpc2 package is updated to support the concept of idle timeout:
a duration after which the server is shut down when there are no
connected clients. This is exposed in the gopls serve command via the

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.

For testability, and to support the exchange of debug information across
Forwarder and server, it is helpful to encapsulate all debug information
on the instance object.
This CL moves all state in the debug package into a new 'State' type,
that is added as a field on the debug.Instance. While doing so, common
functionality for object collections is factored out into the objset
helper type.
Also add two new debug object types: Client and Server. These aren't yet
used, but will be in a later CL (and frankly it was easier to leave them
in this CL than to more carefully rewrite history...).

The code to check if a candidate object matches our candidate
inference had become complicated, messy, and in some cases incorrect.
The main source of the complexity is the "derived" expected and
candidate types. When considering a candidate object "foo", we also
consider "&foo", "foo()", and "*foo", as appropriate. On the expected
side of things, when completing the a variadic function parameter we
expect either the variadic slice type and the scalar element type.
The code had grown organically to handle the expanding concerns, but
that resulted in confused code that didn't handle the interplay
between the various facets of candidate inference.
For example, we were inappropriately invoking func candidates when
completing variadic args:
func foo(...func())
func bar() {}
foo(bar<>) // oops - expanded to "bar()"
and we weren't type matching functions properly as builtin args:
func myMap() map[string]int { ... }
delete(myM<>) // we weren't preferring (or invoking) "myMap()"
We also had methods like "typeMatches" which took both a "candidate"
object and a "candType" type, which doesn't make sense because the
candidate contains the type already.
Now instead we explicitly iterate over all the derived candidate and
expected types so they are treated the same. There are still some
warts left but I think this is a step in the right direction.

Add support for var/func/const/type/import keywords at the file scope.
I left out "package" because, currently, if you are completing
something that means you must already have a package declaration. The
main hurdle was that anything other than a decl keyword shows up as
an *ast.BadDecl at the file scope. To properly detect the prefix we
manually scan for the token containing the position.
I also made a couple small drive-by improvements:
- Also suggest "goto" and "type" keywords in functions.
- Allow completing directly before a comment, e.g. "foo<>//". I
needed this for a test that would have been annoying to write
otherwise.
