memoization CL out into their own change. This will clean up the diffs
in the memoization CL.

This adds an IDs map to the metadata cache, which maps package paths to
IDs. This is only ever used by the Import function in the type checker.

Previously when you added a new file to an existing package, the new
file would get stuck with the "no package for file" error until you
saved the file and then made changed a different file in the
package. There were two changes required to fix the errors:
First, we need to invalidate the package cache when a new file is
added to a package so that the package will actually re-parse and
re-type check. We now notice if file names changed when updating a
package's metadata and invalidate the package cache accordingly.
Second, when dealing with overlay (unsaved) files, we need to map
the *goFile to the package even if we fail to parse the
file (e.g. the new file fails to parse when it is empty). If we don't
map it to the package, the package won't get refreshed as the file is
changed.

This change replaces the strings that were previously used for both the
ID and package path fields. This is a precursor to the change that will
replace the uses of package path with package ID.

Now the "type" of a *ast.PkgName is the package it points to. Of
course, a package is not a real types.Type, but we can still jump you
there. We have to pick one of the package's files, so we choose the
longest one, hoping it is the most interesting.
Similarly, the "definition" of an *ast.ImportSpec is the package being
imported.
I also added a nil check for the package in SignatureHelp. This panics
for me occasionally.

Prior to this change, if a package was rendered invalid by a change in
one of its dependencies, diagnostics would not be propagated until the
user typed in one of the package's files. Now, these updated diagnostics
are sent along with the diagnostics for the dependency.

The "analyses" cache in lsp/cache.(*Package).GetActionGraph was not
getting cleared on errors. This could result in future calls to
GetActionGraph waiting on the "ready" channel indefinitely. This in
turn caused the goroutine in cacheAndDiagnose to block indefinitely
and never send the diagnostic results back.
Now we use a defer statement to always close the channel. If we did
not succeed, we also clear out the cache entry and set a "succeeded =
false" flag to signal waiters that they need to retry. If in the
future errors other than context.Canceled/Timeout are possible, this
retry behavior may need to be revisited.

This change brings back handling for circular imports, which was removed
because I originally thought that go/packages would handle that.
However, since we are type-checking from source, we still end up having
to deal with that.
Additionally, we propagate the errors of type-checking to the
diagnostics so that the user can actually see some of the problems.

This change adds a Package interface to the source package, which allows

unnecessary fields in a *go/packages.Package).
This change also adds an analysis cache for each package, which is used
to cache the results of analyses to avoid recomputation.
