Deep completion refers to searching through an object's fields and
methods for more completion candidates. For example:
func wantsInt(int) { }
var s struct { i int }
wantsInt(<>)
Will now give a candidate for "s.i" since its type matches the
expected type.
We limit to three deep completion results. In some cases there are
many useless deep completion matches. Showing too many options defeats
the purpose of "smart" completions. We also lower a completion item's
score according to its depth so that we favor shallower options. For
now we do not continue searching past function calls to limit our
search scope. In other words, we are not able to suggest results with
any chained fields/methods after the first method call.
Deep completions are behind the "useDeepCompletions" LSP config flag
for now.

every blocking the routine that handles replies.
It also protects against repeated or missing replies.

Previously we would always expand *types.Func completion candidates to
function calls, even if the expected type matched the function itself,
not its return value. Now we check the function itself before we check
its return value. This fixes cases like this:
func foo() int { return 0 }
var f func() int
f = <foo> // now completes to "foo" instead of "foo()"
Also, *types.Var function values were never getting expanded to calls.
I fixed the completion formatting to know that both *types.Func
and *types.Var objects might need to be invoked in the completion
item. This fixes cases like this:
foo := func() int { return 0 }
var i int
i = <foo()> // now completes to "foo()" instead of "foo"

if we want to complete to "buf" properly we need to apply the "&" type

incorrect in this situation since it is nonsensical to
