Make pointers returned via TIFFGetField const
According to http://bugzilla.maptools.org/show_bug.cgi?id=2125#c6
callers are not allowed to modify pointer or array values returned from
TIFFGetField or the like. So, make this explicit in the documentation
by specifying these things as const. Note that this is not an ABI
change, since C does not encode const in libraries. Also, this is
not really an API change, since the varargs call strips away all
the types anyway. So it really is more of a documentation change.
fixes #11
