Andrey Smirnov 7a5da60e26 Change USB strings handling code ...

This commit add an extra field to the _usbd_device, that allows to
keep track of the number of USB strings  which allows simplify
boundaries checking code in usb_standard_get_descriptor.

This commit also changes the index base for strings in
usb_standard_get_descriptor which allows to get rid of necessity to
have a dummy one-character string in a strings array.
