The status display was reading the state while the task was updating
it. Use a mutex to prevent the race.

With the current btrfs-convert, if we convert a ext4 without data checksum,
it'd not set nodatasum flag in inode item, nor create csum item, reading
file ends up with checksum errors.

With larger file system (in this case its 22TB), ext2fs_open() returns
EXT2_ET_CANT_USE_LEGACY_BITMAPS error message with
ext2fs_read_block_bitmap().
To overcome this issue,
(a) we need pass EXT2_FLAG_64BITS flag with ext2fs_open.
(b) use 64-bit functions like ext2fs_get_block_bitmap_range2,
ext2fs_inode_data_blocks2,ext2fs_read_ext_attr2
(c) use 64bit types with btrfs_convert_context fields

Build under musl libc fails because of missing PATH_MAX and XATTR_NAME_MAX
macro declarations. Add the required headers.

Rename 'free' and also 'used' for consistency.

Use one flag field instead of several variables. The change cascades
down to the callchain and modifies several functions.
