All functions now follow a consistent error reporting scheme. A negative return value always indicates an error condition. A return value of 0 always indicates success, except for the few functions which have to return a count of bytes or directory records upon success. Previously, it was hard to tell what function returned what in case of error, which led the bugs in smba_write() and smba_read(), neither of which gracefully fell back on SMB_COM_WRITE/SMB_COM_READ, respectively if SMB_COM_WRITE_RAW/SMB_COM_READ_RAW failed. State variables are now named according to their respective purpose where possible. Previously, it was "rval", "errnum", "result" which were used almost interchangeably regardless of purpose.
