configure.in, configure: include/config.h.in: Added stropts and poll.
include/smb.h: Moved old typedefs of uint8 etc. into include/includes.h where
               all the other defines live (changed them from typedefs to
               defines).
Other changes : changed from using uint32 to SMB_DEV_T and SMB_INO_T
in preparation for moving to size independed (ie. 64 bit clean) device
and inode access. Stat call wrapper comes next :-).
