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.

This change sends the expected boolean value for 'renameProvider'
to the client.
When a client does not send 'prepareSupport' in its initial
'initialize' request, the client expects to get a boolean value for
'renameProvider'. Since we do not yet provide prepare support, we just
set 'renameProvider' to true regardless of the value of prepareSupport.

This change provides support to rename identifiers within a single
package.
The renaming is performed by finding all references to an identifier,
and then creating text edits to replace the existing text with the
new identifier.
Editing an import spec is not supported.

This change removes the explicit configuration for improved
documentation on hover. We use a comment's synopsis rather than the full
comment.
However, we also add a "noDocsOnHover" setting that is used by the cmd
tests. Ultimately, no one should use this setting and we should remove
it. We leave it temporarily because the cmd tests still need work.
