Clean: divide the source files

soundmanager.c becomes bigger, so divide it into some files.

soundmanager.h ... declare functions and set entry point of binder
sm_def.h ... define keys for json, default value and so on
soundmanager.c ... implementation

-/**
- * Call "connect" function of Audio Manager.
- * Getting resource right to output audio stream.
- * Please input following keys with value into json string object in argument.
- * In case of using libsoundmanager,

- *
- * The order of arguments is not important.
- *
- * #### Parameters
- * Request key
- * - sourceID   : Source ID getting in return value in registerSource or appname.
- * - sinkID     : Sink ID. This should be more than 0. If no request, defalut value is set by sound manager
- *
- * This will be changed in near future because these arguments should be aliased like
- * sinkID:100 -> sinkID:"speaker"
- *
- * This will be modified after integrating
- *
- * #### Return
- * - error      : Error status number. If error is 0, it means the request is accepted, otherwise error message is attached with error code in reply message.
- *
- * #### Note
- * sourceID and sinkID should be more than 0
