Btrfs-progs: fix some build warnings on 32bit platform
Fix following build warnings on 32bit platform:
...
utils.c:1708:3: warning: left shift count >= width of
type [enabled by default]
if (x << i & (1UL << 63))
^
qgroup-verify.c:393:9: warning: cast to pointer from integer
of different size [-Wint-to-pointer-cast]
return (struct tree_block *)unode->aux;
^
qgroup-verify.c:407:38: warning: cast from pointer to integer
of different size [-Wpointer-to-int-cast]
if (ulist_add(tree_blocks, bytenr, (unsigned long long)block, 0) >= 0)
^
cmds-restore.c:120:4: warning: format %lu expects argument of type
long unsigned int, but argument 3 has type size_t [-Wformat=]
fprintf(stderr, "bad compress length %lu\n", in_len);
...
BTW, this patch also switches other castings with new helpers.
