This patch moves fake.go to mount_fake.go, and follows to principle of always returning a discrete type rather than an Interface. All callers of "FakeMounter" are changed to instead use "NewFakeMounter()". The FakeMounter "Log" struct member is changed to not be exported, and instead only access through a new "GetLog()" method.
