Rather than building cusom events and driving the exporter, the test now
registers a custom exporter and then uses the normal higher level methods to
deliver events to it.
This means we are testing the actual information that would arise in a user
program, and also means we no longer have to expose internal features just for
tests.
Metrics are not fully converted yet.

This allows early exporters to adjust the event for later ones.
This is used to lookup key values from the context if needed.
Also add a Query type event which is intended to perform all event
modifications but nothing else, and is used to lookup values from
the context. This cleans up a weirdness where the current lookup
presumes there will be an exporter with a matching mechanism.

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
the LSP forwarder:
-remote.listen.timeout: -listen.timeout for the auto-started daemon
-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
a bit hard to understand, so I decided to go ahead and switch to a
variadic options pattern for initializing both the Forwarder and
StreamServer, the latter just for consistency with the Forwarder.

switch {
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 {

Second I had to add logic to manually extract the completion prefix
inside empty switch statements, and finally some logic to offer (only)

offers the candidate:
if err != nil {

where <> denotes a placeholder so you can easily alter "err".
The completion will only be offered when:
1. The position is in a function that returns an error as final result
value, and
2. The statement preceding position is an assignment whose final LHS
value is an error.
The completion will contain zero values for the non-error return values
