The -json and -c=N flags, formerly belonging only to the
go/packages-based {single,multi}checkers, are now supported by
unitchecker as well.
The no-op -source, -v, -all, and -tags flags, formerly belonging only
to unitchecker, have moved to the analysisflags package, which is
common to all checkers.
The -flags flag now reports all registered flags (except the
{single,multi}checker-only debugging flags) rather than just those
related to analyzers, allowing one to say: 'go vet -json' or 'go vet -c=1'.
The code for printing diagnostics, either plain or in JSON, has been
factored and moved into the common analysisflags package.
This CL depends on https://go-review.googlesource.com/c/go/+/149960 to
cmd/go, which causes 'go vet' to populate the ID field of the *.cfg.
This field is used as a key in the JSON tree.
Added basic tests of the new -json and -c unitchecker flags.

(By "vet lite", we mean static tools that must be invoked by a build
system, such as 'go vet'.)
This CL publishes the former internal/unitchecker package.
Its misnamed Main function is renamed Run, and it has a new Main
that does the steps of a real main (log, flag, etc).
The motivation for this change is to reduce cmd/vet-lite to the point
of triviality to simplify the maintenance of the vendored copy of
x/tools in GOROOT, because GOROOT/src/cmd/vet will need a copy of that
logic. It is now essentially a one-liner.
Also, improve usage messages; analysisflags.PrintUsage wasn't
appropriate for all callers so it has been eliminated.
Each of {single,multi,unit}checker prints its own 1-line usage message.

- add a no-op -tags flag for legacy compatibility.
Tags processing is done by go vet, but it passes the flag on.
Exercised by cmd/go TestGoVetWithTags.
- rename OtherFiles to NonGoFiles in the JSON *.cfg file, to match
the name actually used for this field (see github.com/golang/go/issues/27665).
We really need to publish the types for this protocol.
Exercised by cmd/go TestScript/vet_asm.
- suppress diagnostics in cfg.VetxOnly mode.
Exercised by cmd/go TestTestVet.

Per discussion with Russ,
the -all/-source/-v flags now silently do nothing, and
the -printffuncs (et al) shims now silently delegate to -printf.funcs, and
the -NAME.enable (et al) flags are now called just -NAME.
Various minor tweaks to command-line help messages.

Details:
- Add -source, -v, and -all flags to vet-lite.
These have no effect and issue a warning.
- Add usage message to vet-lite that lists all
analyzers and explains -foo.enable and other flags.
- Factor this help message (common to vet-lite and
multichecker) into analysisflags.
- Add legacy aliases of new flags.
e.g. -printfuncs is now -printf.funcs
The old names work but issue a warning when used.
Also: update comments to say -vettool not$GOVETTOOL
I think we should probably do away with singlechecker
in a follow-up: a singleton multichecker is good enough,
and will allow us to remove cases in the flag-processing
logic.

Also:
- add cmd/vet-lite, a version of cmd/vet that doesn't depend on
go/packages and must be run under "go vet". This will be vendored
into $GOROOT/src/cmd/vet.
- add an integration test for a unitchecker-based command under "go vet".
