Additions: relicence components needed for Linux shared folders to MIT. bugref:9109: Shared folders: update to match in-kernel code more closely This change makes the code on which the Linux kernel shared folder patch is based MIT-licenced, so that the version in the Linux kernel can be too. This would make it easier to move code back and forth.

42	/** @page pg_guest_lib VirtualBox Guest Library
43	*
44	* This is a library for abstracting the additions driver interface. There are
45	* multiple versions of the library depending on the context. The main
46	* distinction is between kernel and user mode where the interfaces are very
47	* different.
48	*
49	*
50	* @section sec_guest_lib_ring0 Ring-0
51	*
52	* In ring-0 there are two version:
53	* - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
54	* who is responsible for managing the VMMDev virtual hardware.
55	* - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
56	*
57	*
58	* The library source code and the header have a define VBGL_VBOXGUEST, which is
59	* defined for VBoxGuest and undefined for other drivers. Drivers must choose
60	* right library in their makefiles and set VBGL_VBOXGUEST accordingly.
61	*
62	* The libraries consists of:
63	* - common code to be used by both VBoxGuest and other drivers;
64	* - VBoxGuest specific code;
65	* - code for other drivers which communicate with VBoxGuest via an IOCTL.
66	*
67	*
68	* @section sec_guest_lib_ring3 Ring-3
69	*
70	* There are more variants of the library here:
71	* - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
72	* - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
73	* drivers which uses special loader and or symbol resolving strategy.
74	* - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
75	* Dylibs.
