dev-serial: add always-plugged property to ensure USB device is always attached

Some operating systems will generate a new device ID when a USB device is unplugged
and then replugged into the USB. If this is done whilst switching between multiple
applications over a virtual serial port, the change of device ID requires going
back into the OS/application to locate the new device accordingly.

Add a new always-plugged property that if specified will ensure that the device
always remains attached to the USB regardless of the state of the backend
chardev.

Patch generated using:

$ ./scripts/codeconverter/converter.py -i \

which will split "typdef struct { ... } TypedefName"

Followed by:

- move the typedefs and #defines above the type check macros

usb-serial: Fix timeout closing the device

Linux guests wait ~30 seconds when closing the emulated /dev/ttyUSB0.
During that time, the kernel driver is sending many control URBs
requesting GetModemStat (5). Real hardware returns a status with
FTDI_THRE (Transmitter Holding Register) and FTDI_TEMT (Transmitter
Empty) set. QEMU leaves them clear, and it seems Linux is waiting for
FTDI_TEMT to be set to indicate the tx queue is empty before closing.

Set the bits when responding to a GetModemStat query and avoid the
shutdown delay.

usb-serial: Increase receive buffer to 496

A FTDI USB adapter on an xHCI controller can send 512 byte USB packets.
These are 8 * ( 2 bytes header + 62 bytes data). A 384 byte receive
buffer is insufficient to fill a 512 byte packet, so bump the receive
size to 496 ( 512 - 2 * 8 ).

usb-serial: chunk data to wMaxPacketSize

usb-serial has issues with xHCI controllers where data is lost in the
VM. Inspecting the URBs in the guest, EHCI starts every 64 byte boundary
(wMaxPacketSize) with a header. EHCI hands packets into
usb_serial_token_in() with size 64, so these cannot cross the 64 byte
boundary. The xHCI controller has packets of 512 bytes and the usb-serial
will just write through the 64 byte boundary. In the guest, this means
data bytes are interpreted as header, so data bytes don't make it out
the serial interface.

Re-work usb_serial_token_in to chunk data into 64 byte units - 2 byte
header and 62 bytes data. The Linux driver reads wMaxPacketSize to find
the chunk size, so we match that.

Real hardware was observed to pass in 512 byte URBs (496 bytes data +
8 * 2 byte headers). Since usb-serial only buffers 384 bytes of data,
usb-serial will pass in 6 64 byte blocks and 1 12 byte partial block for
462 bytes max.
