235a7d8f80 goose: allow non-injector code to live along with injectors
Previously, goose would ignore declarations in the //+build gooseinject
files that were not injectors. This meant that if you wanted to write
application-specific providers, you would need to place them in a
separate file, away from the goose injectors. This means that a typical
application would have three handwritten files: one for the abstract
business logic, one for the platform-specific providers, one for the
platform-specific injector declarations.

This change allows the two platform-specific files to be merged into
one: the //+build gooseinject file. goose will now copy these
declarations out to goose_gen.go. This requires a bit of hackery, since
the generated file may have different identifiers for the imported
packages, so goose will do some light AST rewriting to address these
cases.

(Historical note: this was the first change made externally, so also in
here are the copyright headers and other housekeeping changes.)

f8e446fa17 goose: use marker functions instead of comments
To avoid making this CL too large, I did not migrate the existing goose
comments through the repository.  This will be addressed in a subsequent
CL.

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.

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.
