b667c4c58e internal/lsp: cache the *ast.File and *token.File on the package
This change removes the need for the ast and token fields on the *goFile
object. We switch to using source.ParseGoHandles on the package, which
means that we can easily access both the AST and token via the package,
which is already cached.

a0f5e6c5c2 internal/lsp: sort rename results
We recommend that gopls integrators apply the []TextEdit responses in
reverse order to get a correct resulting document. This strategy works
when the response is already sorted. Have gopls return sorted []TextEdit
for each file.

4298585011 internal/lsp: provide deep completion candidates
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.

They always are a valid file URI, and we would fail miserably to cope if they were

and don't want to cope with an error that cannot occur.
If we ever have not file uri's, you will have to check if it is a file before calling
.Filename, which seems reasonable anyway.

b012c19798 internal/lsp: trim ASTs for which we do not require function bodies
This change trims the function bodies from the ASTs of files belonging to
dependency packages. In these cases, we do not necessarily need full
file ASTs, so it's not necessary to store the function bodies in memory.

This change will reduce memory usage. However, it will also slow down
the case of a user opening a file in a dependency package, as we will
have to re-typecheck the file to get the full AST. Hopefully, this
increase in latency will not be significant, as we will only need to
re-typecheck a single package (all the dependencies should be cached).

f217c98fae internal/lsp: fix completion insertion
The insertion range for completion items was not right. The range's
end was 1 before the start. Fix by taking into account the length of
the prefix when generating the range start and end.

Now instead of a "prefix", we track the completion's
"surrounding". This is basically the start and end of the abutting
identifier along with the cursor position. When we insert the
completion text, we overwrite the entire identifier, not just the
prefix. This fixes postfix completion like completing "foo.<>Bar" to
"foo.BarBaz".
