117	*
118	* Shared Folders map a host file system to guest logical filesystem.
119	* A mapping represents 'host name'<->'guest name' translation and a root
120	* identifier to be used to access this mapping.
121	* Examples: "C:\WINNT"<->"F:", "C:\WINNT\System32"<->"/mnt/host/system32".
122	*
123	* Therefore, host name and guest name are strings interpreted
124	* only by host service and guest client respectively. Host name is
125	* passed to guest only for informational purpose. Guest may for example
126	* display the string or construct volume label out of the string.
127	*
128	* Root identifiers are unique for whole guest life,
129	* that is until next guest reset/fresh start.
130	* 32 bit value incremented for each new mapping is used.
131	*
132	* Mapping strings are taken from VM XML configuration on VM startup.
133	* The service DLL takes mappings during initialization. There is
134	* also API for changing mappings at runtime.
135	*
136	* Current mappings and root identifiers are saved when VM is saved.
137	*
138	* Guest may use any of these mappings. Full path information
139	* about an object on a mapping consists of the root identifier and
140	* a full path of object.
141	*
142	* Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP
143	* function which returns current mappings. For guest convenience,
144	* removed mappings also returned with REMOVED flag and new mappings
145	* are marked with NEW flag.
146	*
147	* To access host file system guest just forwards file system calls
148	* to the service, and specifies full paths or handles for objects.
