Change span to hide its fields and have validating accessors
This catches the cases where either the offset or the position is being used
when it was not set.
It also normalizes the forms as the API now controls them, and allows us to
simplify some of the logic.
The converters are now allowed to return an error, which lets us cleanly
propagate bad cases.
The lsp was then converted to the new format, and also had some error checking
of its own added on the top.
All this allowed me to find and fix a few issues, most notably a case where the
wrong column mapper was being used during the conversion of definition results.

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

This change allows golsp to be run on a port, with an intermediary
command passing the data through. This allows for improved logging.
Also, add necessary changes to VSCode integration to allow changing the
name of the command for golsp.

Refactor code as a follow-up to

Also, change every instance of "source.URI()" to "fromProtocolURI", so
that we can add a better implementation of that later on (for Windows
support).

Added a View interface to the source package, which allows for reading
of other files (in the same package or in other packages). We were
already reading files in jump to definition (to handle the lack of
column information in export data), but now we can also read files in
diagnostics, which allows us to determine the end of an identifier so
that we can report ranges in diagnostic messages.

It also adds code for using struct fields as flags to allow us to remove all the

This change adds support for goimports as a code action that can be run
on save. However, there do appear to be issues with the propagation of
the context.Only field of the CodeActionParams, so we treat every
codeAction as an organizeImports action - this should be fixed in the
next vscode-languageclient release
(https://github.com/Microsoft/vscode-languageserver-node/issues/442).
