delete import "xxx" in package xxx.

inside package xxx, xxx is not declared
anymore so s/xxx.//g

delete file and package level forward declarations.

note the new internal_test.go and sync
and strconv to provide public access to
internals during testing.  the installed version
of the package omits that file and thus does
not open the internals to all clients.
