New API call for path conversion

On second thought, when I see path, I think path list (POSIX defines 
'path' as a single file name, but the GNU Coding Standards frown on that 
definition as it is often confused with $PATH).  cygwin_conv_name doesn't 
quite work either (POSIX defines 'name' as a component in the middle of a 
path that doesn't contain a directory separator).  cygwin_conv_file 
implies that the name maps to an existing file, which is not necessarily 
the case.  Maybe cygwin_conf_file_name for one, and cygwin_conf_path_list 
for multiple?

At any rate, a rose by any other name is still a rose - as long as the 
names of the single vs. list converters are justifiable, and the semantics 
are documented, I'll live with it.
