2013-08-19ringbuffer: fix the ambiguous nameGrissiom
RT_RINGBUFFER_SIZE could mean "the size of the whole buffer", "the size of the empty space" or "the size of the data". Moreover, it's never a micro anymore. Change it to rt_ringbuffer_data_len before it's too late. Also, RT_RINGBUFFER_EMPTY is changed to rt_ringbuffer_space_len.

Reset the vcom state in class_{run,stop} and when the PC is not receiving data from me.
2013-05-12cdc_vcom: not to start sending data when the data is already sendingGrissiom
We start the sending transaction in SOF handler. But if the data is already sending, start an other transaction will cause data lose. Implement a state machine is cdc_vcom and avoid that.

The data filled into dcd_ep_write does not to be limited by MaxPacketSize.

2013-05-09cdc_vcom: fix the bug that use ringbuffer pool as usb packet bufferGrissiom
This commit set the buffer for packet to CDC_MaxPacketSize which is a reasonable value for it. However, maybe we should make CDC_{RX,TX}_BUFSIZE configurable as well.
