108	*
109	* Shared Folders map a host file system to guest logical filesystem.
110	* A mapping represents 'host name'<->'guest name' translation and a root
111	* identifier to be used to access this mapping.
112	* Examples: "C:\WINNT"<->"F:", "C:\WINNT\System32"<->"/mnt/host/system32".
113	*
114	* Therefore, host name and guest name are strings interpreted
115	* only by host service and guest client respectively. Host name is
116	* passed to guest only for informational purpose. Guest may for example
117	* display the string or construct volume label out of the string.
118	*
119	* Root identifiers are unique for whole guest life,
120	* that is until next guest reset/fresh start.
121	* 32 bit value incremented for each new mapping is used.
122	*
123	* Mapping strings are taken from VM XML configuration on VM startup.
124	* The service DLL takes mappings during initialization. There is
125	* also API for changing mappings at runtime.
126	*
127	* Current mappings and root identifiers are saved when VM is saved.
128	*
129	* Guest may use any of these mappings. Full path information
130	* about an object on a mapping consists of the root identifier and
131	* a full path of object.
132	*
133	* Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP
134	* function which returns current mappings. For guest convenience,
135	* removed mappings also returned with REMOVED flag and new mappings
136	* are marked with NEW flag.
137	*
138	* To access host file system guest just forwards file system calls
139	* to the service, and specifies full paths or handles for objects.
