This change adds an additional cache for type information, which here is
just a *packages.Package for each package. The metadata cache maintains
the import graph, which allows us to easily determine when a package X
(and therefore any other package that imports X) should be invalidated.
Additionally, rather than performing content changes as they happen, we
queue up content changes and apply them the next time that any type
information is requested.

Like the previous change to the FIle interface, we treat Read as if it were an
accessor, we remember the content part but not the error part, and we may fill
it in asynchronously, so this change makes it explicit.
In the future we should probably trap the error in the read and push it back
through another channel though, it will be the root cause of later errors.

we don't really use them, only generate them in cases where the failure is way more fundamental, and then also fail
to remember them for the next call to the same accessor. Better to not have them.

This change makes sure to handle escaped characters, for instance, files
in the module cache contain "@" in the path. Also, return errors when a
package is not found for a file.

Refactor code as a follow-up to

Also, change every instance of "source.URI()" to "fromProtocolURI", so
that we can add a better implementation of that later on (for Windows
support).

This change separates a cache package out of the
golang.org/x/tools/internal/lsp/source package. The source package now
uses an interface instead a File struct, which will allow it be reused
more easily. The cache package contains the View and File structs now.

This makes the format code use the AST that is already cached on the file to do
the formatting. It also moves the core format code into the source directory.

I realized this was a mistake, we should try to keep the source
directory independent of the LSP protocol itself, and adapt in
the outer layer.
This will keep us honest about capabilities, let us add the
caching and conversion layers easily, and also allow for a future
where we expose the source directory as a supported API for other
tools.
The outer lsp package then becomes the adapter from the core
features to the specifics of the LSP protocol.

A file is strongly associated with a view, and knows how to manage it's own
contents.
We can also now track files that are not "active"

This allows us to write the lsp verbs in terms of a stable underlying source
management layer.
This should make it easier to refactor the underlying layer to add more powerful
caching and incremental modes as we go.

Any time a file is changed, we compute diagnostics for its package and
return them to the client. No caching is implemented yet, so we parse
and type-check the package each time.
