Most of our code was including Log.h even though that is not where the "lldb" log channel is defined (Log.h defines the generic logging infrastructure). This worked because Log.h included Logging.h, even though it should. After the recent refactor, it became impossible the two files include each other in this direction (the opposite inclusion is needed), so this patch removes the workaround that was put in place and cleans up all files to include the right thing. It also renames the file to LLDBLog to better reflect its purpose.
