FT232x driver: support hardware flow control.

We had everything in place, except we never actually sent the command to
the device.

Note that the other drivers (prolific, etc) as well as pc_serial need to
be updated as well (might do it when I get access to hardware where I
can test the changes).

usb_serial: add PID for FTDI FT231X.

- Same driver as other FTDI chips, but less IO pins.

usb_serial: clean up usb device identification

* Update FTDI, KLSI, Prolific, and Silicon drivers to share a
common structural layout for device identification.
* More flexible and cleaner than massive switch case statements.
* Avoids the problem of different chipsets from identical vendors.

Switched to use USB_cdc.h definitions.
Expanded search in every configuration, not only first. ELSA USB modem for instance
publish two configurations, the first one being a vendor-specific one for
Windows NT.
ACMDevice now don't assume anymore union functional descriptor is always there.
The data interface index can be found also in Call Management (CM) functional
descriptor.

(Style cleanup pending...)

- change KLSI init the way it's done by the linux driver
- do not count usb headers as part of count returned by write(), else we might end up writing more than the passed amount :)

Rework of the usb_serial driver:
* Refactored everything to C++ with the different devices as subclasses
* Added proper ACM detection with parsing of the ACM descriptors
* Added device transfer error handling and fixed some concurency issues
* Big cleanup to conform to our style guide

This should make at least ACM stable to use. Commiting this over my K850i with
ACM compliant USB modem and UMTS data connection. Note that support for all
other device classes (Prolific, FTDI and KLSI) is untested but should work the
same as before. Note also that since we currently lack a TTY module this will
only build/work for R5 or Dano with the proper TTY headers.
