Implement rudimentary reference counting for sqfs_object_t2023-01-19T15:24:56+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2022-12-04T00:33:45+00:00urn:sha1:47f24f2a8faf71395a1d054e9823beb000442cce
Implement grab/drop functions to increase/decrease reference count
and destroy the object if the count drops to 0.
Make sure that all objects that maintain internal references actually
grab that reference, duplicate it in the copy function, drop it in
the destroy handler.

Make sqfs_tree_node_get_path more robust2022-07-08T17:17:35+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2022-07-05T10:16:36+00:00urn:sha1:75063b2e14dacc13fcbeeba24e580198a7c1c638
Test against various invariants:
- Every non-root node must have a name
- The root node muts not have a name
- The name must not be ".." or "."
- The name must not contain '/'
- The loop that chases parent pointers must terminate, i.e. we must
never reach the starting state again (link loop).
Furthermore, make sure the sum of all path components plus separators
does not overflow.

sub directory and fix up the includes that make use of them.
