33	/* Shared Folders Host Service.
34	*
35	* Shared Folders map a host file system to guest logical filesystem.
36	* A mapping represents 'host name'<->'guest name' translation and a root
37	* identifier to be used to access this mapping.
38	* Examples: "C:\WINNT"<->"F:", "C:\WINNT\System32"<->"/mnt/host/system32".
39	*
40	* Therefore, host name and guest name are strings interpreted
41	* only by host service and guest client respectively. Host name is
42	* passed to guest only for informational purpose. Guest may for example
43	* display the string or construct volume label out of the string.
44	*
45	* Root identifiers are unique for whole guest life,
46	* that is until next guest reset/fresh start.
47	* 32 bit value incremented for each new mapping is used.
48	*
49	* Mapping strings are taken from VM XML configuration on VM startup.
50	* The service DLL takes mappings during initialization. There is
51	* also API for changing mappings at runtime.
52	*
53	* Current mappings and root identifiers are saved when VM is saved.
54	*
55	* Guest may use any of these mappings. Full path information
56	* about an object on a mapping consists of the root identifier and
57	* a full path of object.
58	*
59	* Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP
60	* function which returns current mappings. For guest convenience,
61	* removed mappings also returned with REMOVED flag and new mappings
62	* are marked with NEW flag.
63	*
64	* To access host file system guest just forwards file system calls
65	* to the service, and specifies full paths or handles for objects.
