Fix panic in schema test
If the swagger files for testing are lost, the func `loadSchemaForTest` or `NewSwaggerSchemaFromBytes` will return a non-nil error and a nil schema. In this case, the calling for `ValidateBytes` will result in panic. So, call Fatalf instead of Errorf.
Also fix minor typos.

Remove Codec from versionInterfaces in meta (RESTMapper is now agnostic
to codec and serialization). Register api/latest.Codecs as the codec
factory and use latest.Codecs.LegacyCodec(version) as an equvialent to
the previous codec.
Currently, the validation logic validates fields in an object and supply default
values wherever applies. This change factors out defaulting to a set of
defaulting callback functions for decoding (see #1502 for more discussion).
* This change is based on pull request 2587.
* Most defaulting has been migrated to defaults.go where the defaulting
functions are added.
* validation_test.go and converter_test.go have been adapted to not testing the
default values.
* Fixed all tests with that create invalid objects with the absence of
defaulting logic.
API object fuzzer is used to randomly populate API object for testing. Similar
code of the fuzzer was duplicated in multiple files. This change refactors the
tests and moves the fuzzer to a separate file.
