In the process of implementation for USB isochronous transfer, the
timeout (100ms) is not enough for Plantronics USB headset. So pass
longer timeout (300ms) to function libusb_control_transfer will
make USB headset of Plantronics work.
This change only results a longer execution time in ENUMERATION process
for few devices like Plantronics USB headset which need more time to do
its internal operations. For most USB devices, time less than 100ms are
enough to complete the execution of libusb_control_transfer. So basically
it will not affect the whole system performance.
In the long term, a better solution (eg: async control transfer) will be
introduced to replace current implementation.

Current ring buffer processing logic assumes every transaction
will be submited to physical device before next transaction
coming. So it use two states 0 (free) and 1 (used) to represent
the state of every data block in the ring buffer. With the help
of the two state, the ring buffer could accept and process data
normally.
But this logic is not proper for ISOC transfer, which generally
submits many transactions even none of them arrive the physical
device. So this patch uses three values to represent the state
of data block in the ring buffer:
USB_XFER_BLK_FREE: this block could be filled with new data;
USB_XFER_BLK_HANDLING: this block is submited to physical device
but response from device is still not received;
USB_XFER_BLK_HANDLED: this block has been processed by physical
device.
The new logic will do different things for each state, which will
make the ISOC transfer work successfully.

And the req/ack message pairs has various types, which

the type of input messages to struct mngr_msg, that is
inconvenient.
We replace payload[0] with an union, which contains all

longer needed. And we can avoid potential out-of-boundary
