go/analysis/cmd/vet-lite: make CLI closer to cmd/vet

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.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
