Rename variables into camelCaset
Use ext2fs_dir_iterate2()
Add new structure DirIterate and pass it to iterate callback
Fix printing dirent (see into length)
Pass DirIterate structure everywhere
Optimize checking for directory.

No need to double call to ext2fs_read_inode() we already have inode
Add brief description
Move ino/inode into DirIterate stucture
Make readDir recursive
Move buffer into DirIterate
Debug: add new helpers for iterating
Get rid off readDirs() function
Fix going into directories only (and avoid "." and "..")
Get rid of rootIno field
Fix dirIterateAddroot(): we need strcat() instead of strcpy()
Fix double slashes in dirIterateAddroot()
Debug: add message for recursive handling
Get rid off buffer for ext2fs_dir_iterate2() and seems that this fix bug
Fix compiler warning about memrchr() by adding _GNU_SOURCE
Fix dirIterateRemoveRoot(): we need to change pointed-ty not pointer

And not current by the byte after "/".

This is the final fix for recursive iterator.
