3345599aaf goose: remove optional directive
This introduces some short-term pain in practice, but I aim to fix that
with the goose.Value directive.

cfc6111ea5 goose: add show command
Lists provider sets in packages given on the command line, including
outputs grouped by what is needed to obtain them.

The goose package now exports the loading phase as an API.

Example output: https://paste.googleplex.com/5509965720584192

1380f96c06 goose: add interface binding
An interface binding instructs goose that a concrete type should be used
to satisfy a dependency on an interface type. goose could determine this
implicitly, but having an explicit directive makes the provider author's
intent clear and allows different concrete types to satisfy different
smaller interfaces.

cb1853b1af goose: use readable variable names
Names are inferred from types most of the time, but have a fallback for
a non-named type. Names are now also disambiguated from symbols in the
same scope.

b92ac73ae3 goose: read tests from testdata
Since tests are all written in terms of Go source, it makes tests easier
to write.  They still need to be arranged in a GOPATH for go build, but
tests that just call Generate can operate in-place because I've faked
the filesystem.

34987b6bee goose: use function name as implicit provider set
Single-element provider sets are frequently useful enough to warrant
being a default.  Larger groupings within a package are less frequent.
