When proposing unimported package members, we start with packages loaded
in-memory first, for three reasons: we know that they're fast, they're
fully typed, and they're probably pretty relevant. I hadn't bothered
doing that for package names, because the first two reasons aren't very
relevant. But the third still is -- loaded packages are a pretty good
approximation for in module scope, etc.
With this change we do package names the same as members, so relevance
should be about as good. Not perfect, but nobody's complained much yet.
Fair bit of copy-and-paste, but I don't want to extend the
getAllCandidates abstraction outside of the imports package yet.

If we release gopls/v0.4.0 soon, we should keep these new analyzers off
by default. They were just merged, so they haven't been used enough to
be enabled, I think. We'll turn them on by default for gopls/v0.5.0.
Also, ended up creating a helper function to check if analysis has been
abled (which fixed a small bug in FindAnalysisError), and another helper
function to enable all analyses for testing purposes.

On case-insensitive file systems, the editor may send us a path that
works but doesn't match the actual file's case. Then when we run go
list, we'll get mismatching paths and everything will break.
We can't reliably fix this problem: tracking what case the editor
expects is too difficult to be worth it. Instead, check the workspace
path and bail if it's mismatched.
Possibly we should also check files on DidOpen or such, but we can start
with this.

To address, this, add two new functions for fake.Editor: RegexpSearch

workspace files and wrappers for regtext.Env.
This allows expressing edits as well as buffer locations in terms of
easily scannable regexps.
An alternative solution to this problem is to integrate markers ala
packagestest. I tried this, but it ended up being cumbersome to
implement and less usable than regexps, due to the static nature of
markers: after the buffer has been edited all markers must be
updated.

func (f foo) doSomething() { }
func (f foo) logic() {

Now at <> we prefer "doSomething()" over "DoSomething()". All else

The same logic is applied to deep completions so we prefer "c.foo.bar"

definition.Run requires a nil check of opts before applying to avoid
panic, and test must be run with markdown enabled.
When running 'go test' without -run flag, connection.initialize() was
not called and there was no problem because the default value of
Options.PreferredContentFormat was Markdown.
In addition, currently using the same connection despite different
options, therefore make to use a different connection for different
options.

This changes the way keys work, there is still a single internal key
implementation for performance reasons, but the public interface is a set of key
implementations that have type safe Of and Get methods.
This also hides the implemenation of Tag so that we can modify the storage form
and find a more efficient storage if needed.
