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 moves gopls from type-checking packages using the
go/packages API to type-checking from source. This is the first step in
adding caching to gopls.

Rather than replacing the whole file on gofmt or goimports, use the Myers
diff algorithm to compute diffs for a file. We send those back as text
edits.

The source package now exposes an Identifier method that returns information
about an identifier, which can be used to implement Definition, TypeDefinition
and Hover, as well as other command line functions in a later cl.

Refactor code as a follow-up to
https://go-review.googlesource.com/c/tools/+/154742.
Also, change every instance of "source.URI()" to "fromProtocolURI", so
that we can add a better implementation of that later on (for Windows
support).

Added a View interface to the source package, which allows for reading
of other files (in the same package or in other packages). We were
already reading files in jump to definition (to handle the lack of
column information in export data), but now we can also read files in
diagnostics, which allows us to determine the end of an identifier so
that we can report ranges in diagnostic messages.

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 change adds a very simple implementation of hovering. It doesn't
show any documentation, just the object string for the given object.
Also, this change sets the prefix for composite literals, making sure we
don't insert duplicate text.

It is impossible to reconstruct a line and column correctly from export data, so
we have to attempt to find open and process the file in order to guess what the
original pos was when we have one that originated in export data.
This occurs in any time in go to definition when the target is not in the same
pacakge as the source.
