This change moves as much view initialization code into the
initialization function, instead of having it happen on view create.
Also, the `go env` variables that are collected at inconsistent times
are all collected on view creation. That is sufficient, since the view
is recreated if the environment changes.
I had originally hoped that the initial call to `go env` and the
-modfile detection could become part of this parallel initialization as
well, but you can't create a *packages.Config until the temporary
modfile has been set up, so it still makes sense to do that on view
create. This is, however, the reasoning behind the refactorings in
the -modfile detection in this CL. The main changes are a few renamings
and a split between snapshot.ModFiles and view.modFiles to maximize the
amount of work done in the view. I changed view.modfiles to moduleInformation
because I thought we might want to store additional information there at some
point. Rohan, please let me know if you disagree with any of the changes I made,

We have multiple use cases for scanning: goimports, import completion,
and unimported completions. All three need slightly different features,
and the latter have very different performance considerations. Scanning
everything all at once and returning it was not good enough for them.
Instead, design the API as a series of callbacks for each
directory/package: first we discover its existence, then we load its
package name, then we load its exports. At each step the caller can
choose whether to proceed with the package. Import completion can stop
before loading exports, goimports can apply its directory name
heuristics, and in the future we'll be able to stop the scan short once
we've found all the results we want for completions.
I don't intend any significant changes here but there may be some little
ones around the edges.

This change adds support for returning versions along with file URIs, so
that the client can know when to apply changes. The version is not yet
propagated along to the internal/lsp/cache package, so this change will
have no effect (VS Code ignores a version of 0 and still applies the
changes).
A few minor changes made in the rename code (to remove the view
parameter). Some minor staticcheck fixes.

Add a new "verboseOutput" config flag (defaults to "false") to enable
verbose go/packages and imports output. Previously this output was
always present.
The go/packages output would dump out the entire (humongous) "go list"
JSON response which would lock up my editor for a second whenever
something triggered a go/packages call.
The imports output would produce a bunch of "gopathwalk" debug
messages that aren't useful in general and in particular add noisy
output to tests.

Loading completion suggestions can be slow, especially in GOPATH mode
where basically anything can change at any time. As a compromise, cache
everything for 30 seconds. Specifically, after a completion operation
finishes, if the cache is more than 30 seconds old, refresh it
asynchronously. That keeps user-facing latency consistent, without
chewing up CPU when the editor isn't in use. It does mean that if you
walk away for an hour and come back, the first completion may be stale.
In module mode this is relatively benign. The only things the
longer caching affects are the main module and replace targets, and
relevant packages in those will generally be loaded by gopls, so they'll
have full, up-to-date type information regardless.
In GOPATH mode this may be more troublesome, since it affects
everything. In particular, go get -u of a package that isn't imported
yet won't be reflected until the cache period expires. I think that's a
rare enough case not to worry about.

Since a user's module cache is generally going to be much bigger than
their main module, one would expect that caching just information about
the module cache would be sufficient. It turns out that's not correct.
When we discover something in the module cache, we have to make sure
that a different version of it isn't already in scope. Doing that can
require information about the main module or replace targets, so that
needs to be cached too.
Concretely, when I'm working in x/tools, if a scan discovers a version
of x/tools in the module cache, it should usually ignore that version.
But that might not be true in more complicated cases, especially those
involving nested modules whose boundaries change.
So, cache everything except GOROOT. Since the new data is mutable,
we store it separately from the module cache data so that it can be
discarded easily between runs.

Scan most sources, including GOPATH, the module cache, the main module,
and replace targets as appropriate. Use the cached stdlib instead of
scanning GOROOT.
We heavily cache the contents of the module cache, so performance is
decent. But we have to look at all the modules not in the module cache
too to get the right versions of modules (see
(*ModuleResolver).canonicalize), which currently isn't cached at all,
even just for a single run. That ends up being pretty expensive.
The implementation changes are relatively small; add package name
loading to scan(), cache that result, and allow callers to control what
directories are scanned so that it can skip GOROOT.
I also cleared out most of the stdlib from the unimported completion
test and added a simple external completion to it for safety's sake.

Now when a file is deleted we force the file's packages to refresh

- Kick off diagnostics in a goroutine to match how DidChange works.
This will allow us to work through big sets of file changes faster,
and will save duplicated work once type checking can be canceled.
- Don't assume a watched file is only part of one view.
Two interesting cases we don't handle yet:
- If the deleted file was the only file in the package, we don't
currently update diagnostics for dependent packages. This requires
rejiggering how diagnostics are invoked a bit.
- If the deleted file is still open in the editor and then later
closed, we don't trigger metadata/diagnostics refresh on DidClose.

This change adds supports for a package belonging to multiple files.
It requires additional packages.Loads for all of the packages to which a
file belongs (for example, if a non-test file also belongs to a package's
test variant).
For now, we re-run go/packages.Load for each file we open, regardless of
whether or not we already know about it.
This solves the issue of packages randomly belonging to a test or not.
Follow-up work needs to be done to support multiple packages in
references, rename, and diagnostics.

This change just separates minor changes made along the course of the
memoization CL out into their own change. This will clean up the diffs

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.

We panic if the uri was not a valid file uri instead
They always are a valid file URI, and we would fail miserably to cope if they were
not anyway, and there are lots of places where we need to be able to get the filename
and don't want to cope with an error that cannot occur.
If we ever have not file uri's, you will have to check if it is a file before calling
.Filename, which seems reasonable anyway.

This change marks any unresolved packages discovered as imports by
go/packages.Load. It re-runs go/packages.Load for any package with
missing imports, which will result in the LSP registering changes in
dependencies.
However, this means that we re-run go/packages.Load on
package's with unresolved imports much more than we normally would, so
it may result in a slowdown or unexpected behavior. I'm not sure if this
is necessarily the correct approach here.
