Use the CDCACM as a SYSLOG output device, send message to remote proc.
If there are more than one CDCACM devices, then a device minor number
may also need to be provided. Default: 0

Make sure that the cdcacm is disconnected before the usbdev gets unregistered.
Also, check if the device is connected or not in cdcuart_txempty (uart_txempty). Otherwise there may be a crash during uart_tcdrain, called in tty close path, if the usbdev unregistration happens during the loop.
This issue can be triggered by monitoring the cable connection status in one thread, sending BOARDIOC_USBDEV_DISCONNECT if the usb cable is detached. In another thread close the ttyACM.

Some USB controllers can receive or send multiple data packets then
generate one interrupt. This mechanism can reduce the number of data
copies. Extend req buf to accommodate this.

When usb is re-enumerated due to the reset signal, we need to push
the rx_pending message into the serial port buffer.

drivers: usbdev: minor fix
drivers: usbdev: usbmsc full speed not available
Change transfer size to be based on maxpacket size.
drivers: usbdev: Fix string ID calculation
For *_STRBASE defines, it already unnecessary because composite device setup
has been changed, it would be calculated by *_composite.c in board sources.
drivers: usbdev: Fix invalid/unsupported command processing
Mass Storage Class shall stall when invalid or unsupported commands
has been recieved.
drivers: usbdev: Remove unnecessary reset logic
drivers: usbdev: Flags comparison fix
drivers: usbdev: Descriptor type mismatch fix when dual speed is enabled
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
