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.

The analysisflags package provides a function to help
ensure that all drivers support consistent command-line
interfaces. In particular, -analyzer.enable flags use
tristate logic as in vet, and the -flags flag dumps
a list of flags in JSON for use by 'go vet' and other
build systems.
This code is in a separate package from internal/checker
(the common parts of multichecker, singlechecker)
because we don't want the forthcoming vet-lite (formerly
known as doctor) driver to have an unnecessary dependency
on go/packages. (When go/packages is promoted to the
standard library we can consolidate them.)
+ Test of tristate analyzer selection logic.
