Move all include files to src/include

- 86Box's own headers go to /86box
- munt's public interface goes to /mt32emu
- all slirp headers go to /slirp (might want to consider using only its public inteface)
- single file headers from other projects go in include root

+ * 86Box	A hypervisor and IBM PC system emulator that specializes in
+ *		running old operating systems and software designed for IBM
+ *		PC systems and compatibles from 1981 through fairly recent
+ *		system designs based on the PCI bus.
+ *
+ *		This file is part of the 86Box distribution.
+ *
+ *		Implementation of the ISA Bus (de)Bugger expansion card
+ *		sold as a DIY kit in the late 1980's in The Netherlands.
+ *		This card was a assemble-yourself 8bit ISA addon card for
+ *		PC and AT systems that had several tools to aid in low-
+ *		level debugging (mostly for faulty BIOSes, bootloaders
+ *		and system kernels...)
+ *
+ *		Definitions for the Advanced Power Management emulation.
