Fix validation of marker dir objects

For marker directory objects, validate_object() always returned False.
This was because st_size from stat was being compared to Content-Length
stored in metadata. Unlike files, for directories st_size is always
4096. Hence the comparison would always be '4096 == 0' which would
fail.

This patch makes the following changes:
* Do size comparison of st_size and Content-Length only for files.
* Get rid of _is_dir everywhere. This will simplify things.
