libusb-dl.h for inclusion from core.c

I got an idea: Load libusb1 by dlopen("libusb-1.0.so.0", RTLD_NOW|RTLD_LOCAL);
and bind symbols during library initialization.

I just listed all calls and made specially crafted include file.

If I include it in core.c, I can remove -lusb-1.0 (well, I have to add -ldl, so
it is theoretically possible to introduce new clashes against libdl. But it is
much less probable.

Now I have to modify the build system to make the solution upstream-able.

To make easy proof of concept, I took testlibusb.c from libusb0 test dir,
renamed print_device to libusb_open, and started with my new libusb.

Before: SIGSEGV
After: Works
