still need to cache packages with the path "command-line-arguments" to

A common annoying mis-completion is as follows:
type foo struct {
field int
}
func (f foo) Field() int { return f.field }
func (f foo) logic() {
if f.f<>
}
Now at <> we prefer "field" over "Field()". Similarly:
type foo struct {
}
func (f foo) DoSomething() { }
func (f foo) doSomething() { }
func (f foo) logic() {
f.d<>
}
Now at <> we prefer "doSomething()" over "DoSomething()". All else
being equally, you normally want private objects over public objects
when the private objects are available.
The same logic is applied to deep completions so we prefer "c.foo.bar"
over "c.Foo().bar".

When searching for deep completions, we can end up enumerating struct
types' fields a lot. Optimize fieldSelections to reduce work:
- Wait until we see an embedded field before we create the "seen"
map.
- Use a callback style to iterate over the struct's fields rather than
returning a slice of fields.
- Change "seen" checking strategy back to track struct types rather
than each individual field.
Struct with 5 non-embedded fields:
name old time/op new time/op delta
Fields-16 293ns ± 1% 20ns ± 2% -93.13% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
Fields-16 120B ± 0% 0B -100.00% (p=0.008 n=5+5)
name old allocs/op new allocs/op delta
Fields-16 4.00 ± 0% 0.00 -100.00% (p=0.008 n=5+5)
Same struct but add an embedded struct with 2 fields:
name old time/op new time/op delta
Fields-16 389ns ± 1% 142ns ± 1% -63.53% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
Fields-16 120B ± 0% 144B ± 0% +20.00% (p=0.008 n=5+5)
name old allocs/op new allocs/op delta
Fields-16 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.008 n=5+5)
I think the alloc/op went up because the "seen" map is no longer
allocated on the stack. There is more room for more optimization, but
it's probably not worth making things more complicated.

Three new flags are added to the serve command, and threaded through to

-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.

ca<>

This gets parsed as:
switch {

Even if we manually recover the "ca" token, "<>" is not positioned
inside the switch statement anymore, so we don't know to offer "case"
and "default" candidates. To work around this, we move the closing
brace down one line yielding:
switch {
