Currently, our hover text by default links point to public documentation
sites (e.g. pkg.go.dev). This doesn't make sense for private repos, so
hide the hovertext link when the import path matches GOPRIVATE.
Implementing this was a little messy. To be optimal I had to thread
the value of goprivate through cache.view, and to be correct I had to
duplicate some code from cmd/go internal.
Regtest will follow after https://golang.org/cl/232983 is submitted.

We had previously not been generating documentation on hover for
package declarations or import specs. We do this by adding a few special
cases, since package declarations don't appear in type information.
Throughout, we make the assumption that only one file in a package will
have the documentation for the package. go/doc just appends
documentation as it sees it. We may be able to do better by checking for
a "Package ..." but that still is not guaranteed. Not sure what the
right approach is, so this assumption may be the best option.

The code for formatting function signatures is fairly confusing.
Factoring out an unexported signature type simplifies things a bit.
Hopefully we'll be able to pull out more formatting logic from the other
features. Ideally, I'd like to return to the separation between
internal/lsp/source and internal/lsp so that a formatting package can be
pulled out and used in internal/lsp.

by pre-computing documentation is actually significantly more than the

needs to be investigated, so we begin by just precomputing all of the
