I've merged the first 2 patches into dev branch with modification (so no
need to resend the first two patches).

The rest patches are still a bit messy, I've set up a new
experimental-dump branch, please check out:

There are some stuffs needing to be resolved in advance:
 1) rename all "dumpfs_" prefix into "erofsdump_";
 2) I feel still uncomfortable when reading get_path_by_nid() and
    erofs_read_dir(). Could we refactor them by introducing
    erofs_for_each_dir() or likewise?
 3) file_category_types and the switch in dumpfs_print_inode() are
    duplicated to me. I think one of them can be removed instead.
 4) please help using "filefrag -v -b1" style when printing extent info
    in erofsdump_show_inode_phy(), like below:

 ext:     logical_offset:        physical_offset: length:   expected: flags:
   0:        0..   20479: 21788270592..21788291071:  20480:             last,eof
