The asprintf function returns -1, and leaves the first parameter
undefined in case of an allocation error. This conflicts with the
code's assumption that the parameter is set NULL on error.
Check all return values of asprintf, and ensure that the string
parameter is not used as a return value on error paths.

There is code that is meant to check for the error of an ioctl, but the
return variable that it checks isn't actually assigned from the ioctl.
Assign the return value before checking it.

Split the project into a UVC gadget library and a test application. To
avoid rolling out a custom build system, switch to CMake.
