- Automatically determine the first argument to check.
- Skip checking matching non-variadic functions.
- Skip checking matching functions accepting non-interface{}
variadic arguments.
- Removed fragile 'magic' code for special cases such as math.Log
and error interface.

Previously format argument was detected via scanning func type args.
This didn't work when func type couldn't be determined if the func
is declared in the external package. Fall back to scanning for
the first string call argument in this case.

cmd/vet's printf checker currently uses a hardcoded map of function
names to expected positions of format strings. We can be a bit more
precise than this by looking up the signature of the function, which
helps when libraries implement functions like Errorf or Logf with
extra arguments like log levels or error codes.
Specifically, the format string param is assumed to be the last string
parameter of the called function.
Fixes#12294.

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.
This CL doesn't use go/doc to parse. It only addresses // comments.

Given, say, var f *os.File, a new vet check in CL 14122 diagnoses:
fmt.Printf("%s\n", f.Name)
fmt.Println(f.Name)
but not
fmt.Printf("%v\n", f.Name)
In all three cases the error is that the argument should be f.Name().
Diagnosing Println but not Printf %v seems oddly inconsistent,
so I changed %v to have the check too. In fact, all verbs now have
the check except %p and %T.
Fixes Dave Cheney's confusion when trying to write an example
of the new vet check advertised in the Go 1.6 release notes.

Printing a function value is nearly useless outside of debugging, but
can occur by mistake when one forgets to call it. Diagnose this.
I did this myself just the other day and it arose in cl/14031.
Easy to fix and seems worthwhile.

cp -r x/tools/cmd/vet cmd/vet without any changes.
The next change will adjust the source to use std
repo go/types and friends.
This may (temporarily) break the build; the next
commit (immediately following) will fix it. We do
it in two commits so that we can see the manual
changes.

Most examples in this issue now better, but #10 is incomplete and I'm not
certain how to reproduce it. It actually looks like a go/types problem, since
the type being reported is coming directly from that package.
