2023-06-15	libio: remove ostream_append_sparse and fallback implementation	David Oberhollenzer
	Instead of a separate append-sparse function, simply accept NULL as an input for append. For both Unix and Win32, a fallback needs to be implemented. For XFRM, we can just memset the input buffer to zero, same for the libsquashfs data writer. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-12	libio: add open handle functions to istream/ostream	David Oberhollenzer
	For the backends, this simplifies the code as both paths (open file and open stdio) use the same basic code. Even when merging them only in the backend, it would be done in a similar way. Making the functions public allows other uses as well. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-11	libio: move istream buffer logic into interall callbacks	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-09	libio: remove eof flag from istream_t interface	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-05	Move dir_entry_xattr_t from libio to libsquashfs	David Oberhollenzer
	The structure and functions are renamed to sqfs_xattr_* instead, an additional helper is added to accept an encoded xattr. Documentation and unit test are added as well. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-05	libio: remove buffer_offset from istream_t	David Oberhollenzer
	Instead, make the buffer const, let the user adjust the pointer and size. The offset can then be inferred in precache. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-04	libio: Move istream_t precache logic into backend implementation	David Oberhollenzer
	The end goal is to remove direct buffer access from the istream_t interfaces and make that opaque. For the tar implementation, this already safes us needless buffer copying, as we essentially allow the user to read-through from the underlying stream.

2023-06-01	libio: split dir_entry_t from dir_iterator_t, add create helper	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-22	libtar: add a dir_iterator_t implementation for tar files	David Oberhollenzer
	The existing istream_t wrapper is mered into this one as well, we can open the files via the iterators open_file_ro function. Unit tests and tar2sqfs are modified accordingly. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-16	libio: add xattr query interface to dir_iterator_t	David Oberhollenzer
	Again, with a dummy implementation for Unix and Windows backends. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-15	libio: remove device number from dir_iterator_t, add flag field	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-14	libio: Add a function to open an istream_t from a directory iterator	David Oberhollenzer
	For the native versions, this is currently dummied out, always returning an error number. The idea is to laster wrap the libtar interface around a directory iterator, here we need that method to support the existing use case in tar2sqfs.

2023-05-14	libio: Move skip function into dir_iterator_t base interface	David Oberhollenzer
	For regular iterator types, it's a no-op, for the tree iterator, it skips the sub tree. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-13	Move directory iterator from libutil to libio	David Oberhollenzer

2023-01-31	Move library source into src sub-directory	David Oberhollenzer
