Introduce a new option to dir-iterator, using dir_iterator_begin()
flags parameter, allowing to control whether or not directories will
be exposed before their contents. In essence, pre-order traversal over
file system entries that are directories.
This changes the default behavior of the dir-iterator API. Instead
of iterating directories before doing so over their contents, the new
default behavior does not expose directories at all. Iteration is still
performed, however, within directories, iterating over any other entry.
Only directory paths are ignored.
To iterate over directories in pre-order, reproducing the previous
default behavior, enable the new flag DIR_ITERATOR_DIRS_BEFORE in the
flags parameter of dir_iterator_begin():
* ignore directories by not setting DIR_ITERATOR_DIRS_BEFORE
* iterate directories pre-order by enabling DIR_ITERATOR_DIRS_BEFORE
Adjust existing callers, in refs/files-backend.c and builtin/clone.c
to enable DIR_ITERATOR_DIRS_BEFORE since these callers require iteration
over directories before doing so over their contents.
Update t/t0066-dir-iterator.sh and t/helper/test-dir-iterator.c to test
the new iteration scheme, which is the new default behavior, and the new
flag DIR_ITERATOR_DIRS_BEFORE which reproduces the old default behavior.
