lsblk: new applet

Add a simple lsblk utility that lists information about block devices. Reads from /sys/block to enumerate devices and displays their size, type, and mount point. Features: - Lists all block devices or specific devices - Shows device size in human-readable format (B, K, M, G, T, P) - Shows device type (disk, loop, partition) - Shows mount point if device is mounted - Sorts devices alphabetically - Minimal implementation (~2.5 kb) Mostly rewritten by vda.linux function old new delta lsblk_main - 511 +511 process_SYS_BLOCK_entry - 460 +460 .rodata 106856 106960 +104 read_ull - 81 +81 packed_usage 35924 35952 +28 compare_devices - 25 +25 applet_names 2856 2862 +6 applet_main 1644 1648 +4 ------------------------------------------------------------------------------ (add/remove: 5/0 grow/shrink: 4/0 up/down: 1219/0) Total: 1219 bytes Signed-off-by: Osama Abdelkader Signed-off-by: Denys Vlasenko
