cope with directory entries returned from readdir(3) with type DT_UNKNOWN
Such directory entries need special handling to make our directory traversal code work on filesystems that do not support the d_type optimization. I found this problem because references stored in the refs/ directory were not shown by 'got log' and 'tog log' when a repository is mounted over NFS. helpful feedback + ok millert@
fix ignores when a path is passed to 'got status'
Problem reported by semarie, who also provided initial regression test code. ok semarie
replace the update_blob_fileindex_entry() helper function
This makes it easier to tell in which code paths we are expecting to handle a potential 'ie' NULL pointer and avoids a pointless search of the file index.
