This change adds the notion of a "workspace directory", which is
basically the set of directories that contains workspace packages. These
are mainly used for replace targets right now. It's a little trickier
than expected because the set of workspace directories can technically
change on any go.mod change.
At first, I wanted DidModifyFiles to report whether there was a change,
but I don't think it's actually that expensive to check on each call
and it complicates the code a bit. I can change it back if you think
it's worth doing.
The parse mod handle changes are because I needed an unlocked way of
parsing the mod file, but I imagine they'll conflict with CL 244769
anyway.
The next CL will be to "promote" replace targets to the level of
workspace packages, meaning we will be able to find references in them.

To manually collect cache entries, we need to know when a snapshot is
idle. Add a reference count in the form of a WaitGroup and keep track of
its uses. The pattern is that any time a snapshot is returned, it comes
with a release function that decrements the ref count.
Almost all uses of a snapshot originate in a user-facing request,
handled in beginFileRequest. There it's mostly an exercise in passing
Snapshots around instead of Views.
In the other places I took the path of least resistance. For file
modifications I tried to minimize the amount of code that needed to deal
with snapshots. For diagnostics I just acquired the snapshot at the

ParseGoHandles serve two purposes: they pin cache entries so that
redundant calculations are cached, and they allow users to obtain the
actual parsed AST. The former is an implementation detail, and the
latter turns out to just be an annoyance.
Parsed Go files are obtained from two places. By far the most common is
from a type checked package. But a type checked package must by
definition have already parsed all the files it contains, so the PGH
is already computed and cannot have failed. Type checked packages can
simply return the parsed file without requiring a separate Check
operation. We do want to pin the cache entries in this case, which I've
done by holding on to the PGH in cache.pkg.
There are some cases where we directly parse a file, such as for the
FoldingRange LSP call, which doesn't need type information. Those parses
can actually fail, so we do need an error check. But we don't need the
PGH; in all cases we are immediately using and discarding it.
So it turns out we don't actually need the PGH type at all, at least not
in the public API. Instead, we can pass around a concrete struct that
has the various pieces of data directly available.
This uncovered a bug in typeCheck: it should fail if it encounters any
real errors.

Due to the runtime's inability to collect cycles involving finalizers,
we can't close over handles in memoize.Functions without causing memory
leaks. Up until now we've dealt with that by closing over all the bits
of the snapshot that we want, but it distorts the design of all the code
used in the Functions.
We can solve the problem another way: instead of closing over the
snapshot/view, we can force the caller to pass it in. This is somewhat
scary: there is no requirement that the argument matches the data that
we're working with. But the reality is that this is not a new problem:
the Function used to calculate a cache value is not necessarily the one
that the caller expects. As long as the cache key fully identifies all
the inputs to the Function, the output should be correct. And since the
caller used the snapshot/view to calculate that cache key, it should
always be safe to pass in that snapshot/view. If it's not, then we
already had a bug.
The Arg type in memoize is clumsy, but I thought it would be nice to
have at least a little bit of type safety. I'm open to suggestions.

Completion could be slow due to calls to astutil.PathEnclosingInterval
for every candidate during formatting. There were two reasons we
called PEI:
1. To properly render type alias names, we must refer to the AST
because the alias name is not available in the typed world.
Previously we would call PEI to find the *type.Var's
corresponding *ast.Field, but now we have a PosToField cache that
lets us jump straight from the types.Object's token.Pos to the
corresponding *ast.Field.
2. To display an object's documentation we must refer to the AST. We
need the object's declaring node and any containing ast.Decl. We
now maintain a special PosToDecl cache so we can avoid the PEI call
in this case as well.
We can't use a single cache for both because the *ast.Field's position
is present in both caches (but points to different nodes). The caches
are memoized to defer generation until they are needed and to save
work creating them if the *ast.Files haven't changed.

We use file identities pervasively throughout gopls. Prior to this
change, the identity is the modification date of an unopened file, or
the hash of an opened file. That means that opening a file changes its
identity, which causes unnecessary churn in the cache.
Unfortunately, there isn't an easy way to fix this. Changing the
cache key to something else, such as the modification time, means that
we won't unify cache entries if a change is made and then undone. The
approach here is to read files eagerly in GetFile, so that we know their
hashes immediately. That resolves the churn, but means that we do a ton
of file IO at startup.
Incidental changes:
Remove the FileSystem interface; there was only one implementation and
it added a fair amount of cruft. We have many other places that assume
os.Stat and such work.
Add direct accessors to FileHandle for URI, Kind, and Version. Most uses
of (FileHandle).Identity were for stuff that we derive solely from the
URI, and this helped me disentangle them. It is a *ton* of churn,
though. I can revert it if you want.

Now that we support authoring cgo packages better, we need a way to
regenerate the C definitions. Doing it automatically is very difficult;
in particular, referencing a new symbol from the C package may require
regeneration, but we don't want to do that for every typo.
For now, give the user a button and make them push it. We attach a
code lens to the import "C" line. This is vulnerable to the usual
user-didn't-save glitches.

Currently, our hover text by default links point to public documentation
sites (e.g. pkg.go.dev). This doesn't make sense for private repos, so
hide the hovertext link when the import path matches GOPRIVATE.
Implementing this was a little messy. To be optimal I had to thread
the value of goprivate through cache.view, and to be correct I had to
duplicate some code from cmd/go internal.
Regtest will follow after https://golang.org/cl/232983 is submitted.

Some code lenses may be undesirable for certain users or editors -- for
example a code lens that runs tests, when VSCode already supports this
functionality outside of the LSP. To handle such situations, support
configuring code lenses via a new 'codelens' gopls option.
Add support for code lens in regtests, and use this to test the new
configuration. To achieve this, thread through a new 'EditorConfig' type
that configures the fake editor's LSP session. It made sense to move the
test Env overlay onto this config object as well.
While looking at them, document some types in source.Options.

We were previously sending diagnostics for nonexistent files, and then
adding them to the snapshot in the process. Remove this behavior, and
add a regression test. Case insensitive filesystems were too confusing
to write a test for, but fortunately, Filippo reported another instance
of this bug, so I used that for the regression test.

This change is the first step in handling golang/go#38136. Instead of
creating multiple diagnostic reports for type error analyzers, we add
suggested fixes to the existing reports. To match the analyzers for
FindAnalysisError, we add an ErrorMatch function to source.Analyzer.
This is not an ideal solution, but it was the best one I could come up
with without modifying the go/analysis API. analysisinternal could be
used for this purpose, but it seemed to complicated to be worth it, and
this is fairly simple. I think that go/analysis itself might need to be
extended for type error analyzers, but these temporary measures will
help us understand the kinds of features we need for type error
analyzers.
A follow-up CL might be to not add reports for type error analyzers
until the end of source.Diagnostic, which would remove the need for the
look-up.

If we release gopls/v0.4.0 soon, we should keep these new analyzers off
by default. They were just merged, so they haven't been used enough to
be enabled, I think. We'll turn them on by default for gopls/v0.5.0.
Also, ended up creating a helper function to check if analysis has been
abled (which fixed a small bug in FindAnalysisError), and another helper
function to enable all analyses for testing purposes.

When caching file data specific to a session (anything with a Version or
tied to a view), we now need to be more careful about the existence of
multiple sessions.
This change fixes a few places where we appear to cache session data
without explicitly referring to the session. In principal this could
cause data corruption in multi-session gopls instances, but I have not
been able to force this to occur in either manual or automated testing.
Also fix a data race to the unsaved overlays:

For testability, and to allow the exchange of debug information when
forwarding the LSP, it will be necessary to access debug information
stored in cache objects. This is cumbersome to do if our constructors
return source interfaces rather than concrete types.
This CL changes cache.New and (*Cache).NewSession to return concrete
types. This required removing NewSession from source.Cache. I would
argue that this makes sense from a philosophical perspective: everything
in the source package operates in a context where the Session and Cache
already exist.
