`stamblerre/gocode`, which is the fork of `mdempsky/gocode` that supports Go 1.11 modules, uses `packages.Load` to load all of the Go code for, among other things, IDE autocomplete support. A common aspect to IDE autocomplete is asking for suggestions very frequently (perhaps at every character typed). Once the user has typed another character, the previous request for autocomplete is invalid and can be canceled.
`packages.Load` already stops its `go list` component if the context is canceled, but if the context is canceled afterward, then it will parse all of the files that it found. This change stops the parsing of Go files once it detects that the context has been canceled. When a file has not been processed due to cancelation, its error will be set to that of the context.
This change dramatically improves the performance of the `stamblerre/gocode` fork when requests have been canceled.

go/packages needs to call `go list` multiple times, which causes
redundant work and slows down goimports. If we reimplement `go list` in
memory, we can reuse state, saving time. `go list` also does work we
don't really need, like adding stuff to go.mod, and skipping that saves
more time.
We start with `go list -m`, which does MVS and such. The remaining work
is mostly mapping import paths and directories through the in-scope
modules to make sure we're giving the right answers. Unfortunately this
is quite subtle, and I don't know where all the traps are. I did my
best.
cmd/go already has tests for `go list`, of course, and packagestest is
not well suited to tests of this complexity. So I ripped off the script
tests in cmd/go that seemed relevant and made sure that our logic
returns the right stuff in each case. I'm sure that there are more cases
to cover, but this hit all the stuff I knew about and quite a bit I
didn't.
Since we may want to use the go/packages code path in the future, e.g.
for Bazel, I left that in place. It won't be used unless the magic env
var is set.
Files in internal and imports/testdata/mod were copied verbatim from
cmd/go.
