build: Enable additional build errors and warnings

Help catch more errors by enabling additional build errors and warnings.
Address some of the warnings seen with these new flags, including moving
the libusb_transfer structure back out of the usbi_transfer structure to
address 'warning: invalid use of structure with flexible array member'.
Apparently a structure ending with a flexible array member is not okay
with the compiler as the last member within another structure.

libusb

Build Status Build Status Coverity Scan Build Status

libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD, Haiku and Solaris userspace. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version (see COPYING).

libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems. Please see the PORTING file for more information.
