Fix the imports text edits by computing it on first principles. This
fixes at least a couple bugs:
- Incorrect handling of positions between \r and \n with windows line
endings.
- Incorrect computation of edits when the imports source prefix is
synthetically terminated with just \n, but the actual source has
\r\n.
This is an unsatisfying solution, necessary because of the interaction
of token.File with file termination (token.File does not capture this
information).
Efforts to fix token.File proved complicated, and this is causing
problems for our users, so I think we should do this for now.

Refactor the lsprpc package to move the logic for 'automatic' server
discovery into an AutoDialer abstraction, which both implements the v2
jsonrpc2 Dialer interface, and provides a dialNet method that can be
used for the existing v1 APIs.
Along the way, simplify the evaluation of remote arguments to eliminate
the overly abstract RemoteOption.

Retrying CL 271477, this time with parts of CL 322650 incorporated.
This CL moves to a model where we don't automatically delete invalidated
metadata, but rather preserve it and mark it invalid. This way, we can
continue to use invalid metadata for all features even if there is an
issue with the user's workspace.
To keep track of the metadata's validity, we add an invalid flag to
track the status of the metadata. We still reload at the same rate--the
next CL changes the way we reload data.
We also add a configuration to opt-in (currently, this is off by
default).
In some cases, like switches between GOPATH and module modes, and when a
file is deleted, the metadata *must* be deleted outright.
Also, handle an empty GOMODCACHE in the directory filters (from a
previous CL).

Add a benchmark for the processing of workspace/didChange notifications,
attempting to isolate the synchronous change processing from
asynchronous diagnostics. To enable this, add a new type of expectation
that asserts on work that has been _started_, but not necessarily
completed. Of course, what we really want to know is whether the current
notification has been processed, but that's ~equivalent to knowing
whether the next one has been started. Really, it's off-by-one, but
amortized over e.g. the 100 iterations of a benchmark we get
approximately the right results.
Also change some functions to accept testing.TB, because in a first pass
at this I modified the regtest framework to operate on testing.B in
addition to testing.T... but that didn't work out as IWL is just too
slow to execute the benchmarks outside of the environment -- even though
we can ResetTimer, the benchmark execution is just too slow to be
usable. It seems like a fine change to accept testing.TB is some places,

type checking, but AFAICT that ends up being more harm than good. For
example, let's say we want to Find References on fmt.Printf in the stdlib.
Before this CL, we'd force a new type check of the fmt package, then
find no references because nothing else would have been checked against
that new version.
While there may be some features that work better in the current regime,
I can't think of any, and we have no test coverage for them. So I'd
rather start with what makes sense, and if we want to change it maybe

Our WorkDone reporting was generating a random token for each unit of
work, even if a token was supplied by the client. Change this to use
the client token if it is non-empty, and skip the
workDoneProgress/create request.
After this change we can no longer rely on tokens being a string.
Update our progress tracking accordingly.

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.

Previously, we were only invalidating workspace packages when the go.mod
changed, but we really need to be invalidating all known packages.

I'm not sure how the regtest didn't catch this - is it possible that
it could unmarshal a single string a slice of string? Either way, I'd
like to get the fix in quicker - I'll try to add more regtests for this
later.
Also, validate the upgrade results more thoroughly.

I finally spent the time to understand why branch changes were causing
unexpected errors. There may be other bugs, but this is the first I
spotted. For batched invalidations, we were overriding the value of
invalidateMetadata for each file, so the results depended on the order
of files in the didChangeWatchedFiles notification.

The logic for extracting a function is quite signficant, and the code
is expensive enough that we should only call it when requested by the
user. This means that we should support extracting through a command
rather than text edits in the code action.
To that end, we create a new struct for commands. Features like extract
variable and extract function can supply functions to determine if they
are relevant to the given range, and if so, to generate their text
edits. source.Analyzers now point to Commands, rather than
SuggestedFixFuncs. The "canExtractVariable" and "canExtractFunction"
functions still need improvements, but I think that can be done in a
follow-up.

When a package consists of files that only fail to parse, we fail to
associate parse errors with the package, and therefore return no
diagnostics. To address this, we need to associate the errors with the
package. This involves adding a *token.File to the parseGoData so that
error messages and positions can be properly extracted, even when there
is no associated AST.

Some modules may need to be added to the go.mod without being associated
with an import statement. In such cases, we show the missing module
diagnostic on the whole go.mod file. This isn't ideal, but mapping to
the full require statement isn't that simple, and this is an easy enough
starting point. The code in mod_tidy.go is becoming more unwieldy - I
think I will clean it up in a follow-up.

This change is a follow-up from CL 242477. We now also surface errors
in indirect dependencies as diagnostics in the go.mod file. Any errors
we cannot match are surfaced as diagnostics on the entire go.mod file.
This isn't the most user-friendly way, but it seems simplest.

This change expands the scope of a workspace to the whole module, if the
user is in module mode. This means that diagnostics will appear and will
be updated for the whole module, even if the user only opens a
subdirectory. Similarly, references and other such queries will always
return consistent results, no matter which directory the user opens.
A new "root" field is added to the view. This is either the view's
folder or its module root. Almost all uses of view.folder have been
changed to view.root.
