bugref:8087: Additions/x11: support non-root X server: make declarations in the R3 guest library hidden by default. The library is always linked statically, but when it was linked into our libGL, the guest library symbols entered the name space of processes loading that, in particularly overriding the same symbols in the X server drivers which need their own, different version of the guest library functions.

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