Details:
- added support for complex numbers as distinct from floats:
%[efg] allows complex; %b does not.
- %p: only Signature, Map, Chan, Slice, unsafe.Pointer allowed.
- %s: allow []byte.
- allow a verb to match map[K]V and []T if it matches K/V/T,
e.g. %d now matches []int. i.e. matching is recursive.
- use go/types' constant folding. literal() is gone.
- group cases together.
Added tests.

A trailing % resulted in a bad error message.
Also clean up a couple of dregs left over from the
refactoring to add indexed formats.

Rewrite the checker to be more flexible and better documented, being
more explicit about parsed format vs. checked arguments.
No attempt yet to do check indexed formats; this just paves the way.
All tests still pass.

Simplify the code a bit, get it working after recent go/types changes,
and handle "%*%" just in case. Preparation for handling argument indexing.

They will be deleted from their current homes once this has landed.
Changes made to import paths to make the code compile, and to find
errchk in the right place in cmd/vet's Makefile.
TODO in a later CL: tidy up vet.
