CL 239754 eagerly initialized the environment. This turns out to be a
problem for gopls, which calls ApplyFixes with no ProcessEnv.
Reinitializing it every time seriously harmed the performance of
unimported completions. Move back to lazy initialization.
Working with invalid options has caused a lot of confusion; this is only
the most recent. We have to maintain backwards compatibility in the
externally visible API, but everywhere else we can require fully
populated options. That includes the source byte slice and the options.
LocalPrefix is really more of an Option than an attribute of the
ProcessEnv, and it is needed in ApplyFixes where we really don't want to
have to pass a ProcessEnv. Move it up to Options.

This CL got away from me a little.
For a number of reasons, the existing goimports API of passing in values
for various GO* values was not working. For one, the number of necessary
variables kept growing. For another, we tried to avoid calling `go env`
in GOPATH mode by using `build.Default`, but that turns out to be buggy;
see golang/go#39838. And finally, it created massive confusion about
whether the values were intended to be read from the OS environment, or
fully evaluated by the `go` command.
There are only two users of the internal imports API, so there really
shouldn't need to be more than two modes. For the command line tool, we
have to call `go env` to deal with the `go/build` bug. So we just do it.
Tests use that same path, but can augment the enviroment to set
themselves up. In contrast, `gopls` needs to fully specify the
environment. It can simply pass in the fully evaluated GO* values.
Finally, make the change I was actually here to make: propagate
GOMODCACHE and use it where appropriate.

Resolvers are lazy initialized. That worked fine until the addition of
the scan semaphore -- it's not a good idea to create that lazily, since
you can't synchronize on a channel that doesn't exist.
Specifically, this caused a gopls hang when completion finished without
needing to use the resolver. In that case, we'd call ClearForNewScan/Mod
on an uninitialized resolver, and then hang receiving from a nil
channel.
Instead, eagerly initialize where convenient, and particularly the scan

Filesystem walks of large GOPATHs/module caches can take seconds,
especially on systems with slow filesystems like MacOS and WSL. We don't
want to block completion requests on walks finishing. At the same time,
cancelling a walk midway through results in an unusable cache, where we
don't know which parts have been scanned so far.
The best option is to run the walks in a separate goroutine. Then we can
detach and let them finish. On the other side, we need to be able to
reattach for the next completion request.
Introduce a new method on caches, ScanAndListen, which first processes
all the items in the cache, then notifies of any new items. This allows
us to reattach to an existing scan without missing anything.
The background scan introduces concurrency to the resolvers where there
wasn't any before. We can't use mutexes, because there's no way to stop
Lock() when a context expires. Use a 1-element semaphore channel to
accomplish the same effect.
Along the way: Only rescan GOPATH if the resolver has been cleared. None
of this makes sense for GOPATH without that. Fix a bug where we were
scanning the main module twice in module mode. Stop loading exports in
module tests, it slows them down a ton.

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.

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.

We intend to use the GOPATH resolver's results during LSP
autocompletion. That means we have to be able to cache its data, same as
we do for modules. Convert it to use a dirInfoCache.
Cache exports in the dirInfoCache. Along the way, store exports as slices
rather than maps. We don't need the extra structure the vast majority of
the time, and the memory overhead is nontrivial.

Add a function that returns all the exported identifiers associated with
a package name that doesn't have an import yet. This will allow
completions like rand<> to return rand.Seed (from math/rand) and
rand.Prime (from crypto/rand).

When proposing packages to import, we can propose more relevant packages
first. Introduce that concept to the pkg struct, and sort by it when
returning candidates.
In all cases we prefer stdlib packages first. Then, in module mode, we
prefer packages that are in the module's dependencies over those that
aren't. We could go further and prefer direct deps over indirect too,
but I didn't have the code for that handy.
I also changed the alphabetical sort from import path to package name,
because that's what the user sees first in the UI.

CL 203820 removes an assumption in go/build that srcDir is in the main
module, since in general it need not be. That requires the use of some
other mechanism for callers to communicate the correct location of the
main module.
Fortunately, we already have a WorkingDir field on the ProcessEnv
struct that does exactly that. We can simply propagate it through if
the corresponding field is present on go/build.Context.
