The header is exported as /usr/include/btrfs-list.h but as it's only a
delcaration, it's not used for anything, so the change is safe.

This header is exported to /usr/include/btrfs but there are no known
users, so the change should be safe.

We can use the new BTRFS_IOC_GET_SUBVOL_ROOTREF and
BTRFS_IOC_INO_LOOKUP_USER ioctls to allow non-root users to list
subvolumes.
This is based on a patch from Misono Tomohiro but takes a different
approach (mainly, this approach is more similar to the existing tree
search approach).

Attempt to use the BTRFS_IOC_GET_SUBVOL_INFO ioctl (added in kernel
4.18) for subvolume_info() if not root. Also, rename
get_subvolume_info_root() -> get_subvolume_info_privileged() for
consistency with further changes.
This is based on a patch from Misono Tomohiro.

async became a keyword in Python 3.7, so, e.g., create_subvolume('foo',
async=True) is now a syntax error. Fix it with the Python convention of
adding a trailing underscore to the keyword (async -> async_). This is
what several other Python libraries did to handle this.

Right now, we're defaulting to top=5 (i.e, all subvolumes). The
documented default is top=0 (i.e, only beneath the given path). This is
the expected behavior. Fix it and make the test cases cover it.

The 'swap' is too generic and clashes with some userspace tools that
compile against btrfs, eg. snapper when including
boost::smart_ptr::scoped_array after kerncompat.h:
/usr/include/boost/smart_ptr/scoped_array.hpp:127:13: error: macro "swap" requires 2 arguments, but only 1 given
a.swap(b);

Found using -Wmissing-prototypes in GCC. This should improve LTO
behavior.
Note that set_free_space_tree_thresholds is an unused function. Adding
inline seems to remove the unused function warning.

Replaced bswap with _ variants bswap_32 etc. While it's a glibc
extension, all of the popular libc implementations (glibc, uClibc, musl,
BIONIC) seem to support it.
Added static inline to two functions to match little endian variants. This
fixes a linking error experienced when compiling on gcc 7.3.0 with LTO,
possibly a bug that was fixed later.

Add a new section, QUOTA RESCAN, to explain why and when we need a full
quota rescan when assigning/removing qgroup relationship.
Also, since 'remove' shares the same options of 'assign', add reference
to 'assign' options for 'remove' subcommand.

Even though we have --rescan option, it still needs the user to manually
specify it or call quota rescan command.
This does not make much sense for the most common usecase and only
confuses users. When the rescan is not desired, the --no-rescan option
can be used, eg. when a mass qgruop assignment happens and the repeated
rescan would slow things down. This is considered a marginal usecase.

Rename the function so its name falls in line with the rest of btrfs
nomenclature. So when we change the uuid of the header it's in fact of
the buffer header. Also remove the root argument since it's used solely
to take a reference to fs_info which can be done via the mandatory eb
argument. No functional changes.

Originally print-tree uses depth first search to print trees.
This works fine until we reach 3 level trees (root node level is 2).
For tall trees whose root level is 2 or higher, DFS will mix nodes and
leaves like the following example:
Level 2 A
/ \
Level 1 B C
/ | | \
Level 0 D E F G
DFS will cause the following output sequence:
A B D E C F G
Which in term of node/leave is:
N N L L N L L
Such mixed node/leave result is sometimes hard for human to read.
This patch will introduce 2 new options, --bfs and --dfs.
--dfs: keeps the original output sequence, and to keep things
compatible it's the default behavior.
--bfs: uses breadth-first search, and will cause better output
sequence like:
A B C D E F G
Which in term of node/leave is:
N N N L L L L
Much better sorted and may become default in the future.

Introduce a new function, btrfs_next_sibling_tree_block(), which could
find any sibling tree blocks at path->lowest_level, unlike level 0
limited btrfs_next_leaf().
Since this function is more generic than btrfs_next_leaf(), also make
btrfs_next_leaf() a wrapper of btrfs_next_sibling_tree_block(), to keep
the interface the same as kernel.
This would provide the basis for later breadth-first search print-tree.
