turn path macros into inline function

Use static inline functions instead of macros for has_dos_drive_prefix,
offset_1st_component, is_dir_sep and find_last_dir_sep in order to let
the compiler do type checking.

The definitions of offset_1st_component and is_dir_sep are switched
around because the former uses the latter.
