2023-06-15	libsquashfs: cleanup the flag situation on istream/ostream functions	David Oberhollenzer
	- The ostream creation functions already have flag arguments, but make them an sqfs_u32 instead of int. - Add flag arguments to the istream functions, sanitzie and forward them when opening the handle. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15	Migrate file istream/ostream from libio to libsquashfs	David Oberhollenzer

2023-06-15	libsquashfs: Add sqfs_open_native_file function	David Oberhollenzer
	Having a function to interpret the flags and open a native file handle simplifies the istream/ostream/file code which shares that decoding part, particularly on windows where the character set needs to be transformed. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15	libsquashfs: Add a get_filename function to sqfs_file_t	David Oberhollenzer
	Similar to the sqfs_istream_t & sqfs_ostream_t interfaces. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15	Move sqfs_istream_t & sqfs_ostream_t into libsquashfs	David Oberhollenzer
	For now, only the interfaces and helper functions are moved, the concrete implementations remain in libio. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
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>
2023-06-07	libsquashfs: Add utility functions to read xattrs into list	David Oberhollenzer
	The common pattern is used in rdsquashfs and sqfs2tar, move the code to libsquashfs. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-05	libsqfs: Add an xattr writer function to add a combined key-value struct	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>
2023-04-01	libsquashfs: remove the default block writer alignment feature	David Oberhollenzer
	The idea of the block align feature was to allow micro-managing that some files are forcefully aligned to 1k/4k ("device block") boundaries, hoping to improve access time at the cost of data density. The feature was not exposed in the tools for a long time and eventuall added to the sort file. Measurement and experimentation showed, that it in fact worsened the read performance on a test system with an old micro SD card as the bottle neck. The feature is removed, and if needed, can be brought back simply by wrapping/sub-classing the default block writer, if need be..
