This change uses the wonderful functions from x/mod to get the proper edits for the quick fixes on a go.mod diagnostic. It also creates a goModData structure to hold the data thats gets passed into the various parse functions, this will help reduce the large function prototypes that can occur when we decompose the logic. It also refactors the Modfiles() function to return span.URIs vs FileHandles.

In golang.org/cl/209419, CheckPackageHandle was renamed to
PackageHandle, but a number of references to CheckPackageHandle remained
in function names and comments.
This CL cleans up most of these, though there was at least one case
(internal/lsp/cache.checkPackageKey) where the obvious renaming
conflicted with another function, so I skipped it.

The early return logic for didOpen events in
(*snapshot).invalidateContent was preventing the creation of a new
snapshot, which was in turn stopping the versions from being updated.
This exposed a fundamental issue in the way we were calculating
workspace diagnostics. Since we weren't waiting for diagnostics to be
completed for an entire snapshot before replying that the server had
been initialized, snapshots were being cloned without any type
information. For quickfix code actions, we assume that we have all
information cached (since we need to have sent the diagnostics that the
quickfix is mapped to), so we were not finding the cached analysis
results.
To handle this in the short-term, we key analyses by their names, and
then regenerate results as-needed for code actions. This is technically
more correct than simply assuming that we have the analyses cached. In a
follow-up CL, I will send a follow-up that will make sure that
snapshots "wait" on each other to be fully constructed before being
cloned.

Code generation has been unified, so that tsprotocol.go and tsserver.go
are produced by the same program. tsprotocol.go is about 900 lines shorter,
partly from removing boilerplate comments that golint no longer requires.
(And partly by generating fewer unneeded types.)
The choice made for a union type is commented with the set of types. There
is no Go equivalent for union types, but making themn all interface{}
would replace type checking at unmarshalling with checking runtime
conversions.
Intersection types (A&B) are sometimes embedded (struct{A;B;}, and
sometimes expanded, as they have to be if A and B have fields with the
same names.
There are fewer embedded structs, which had been verbose and confusing to
initialize. They have been replaced by types whose names end in Gn.
Essentially all the generated *structs have been removed. This makes
no difference in what the client sends, and the server may send a {}
where it previously might have sent nothing. The benefit is that some
nil tests can be removed. Thus 'omitempty' in json tags is just
documentation that the element is optional in the protocol.
The files that generate this code will be submitted later, but soon.
