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

The context is zeroed in convert_open_fs after and overwrites the rbtree
initialization, which accidentally is the same (NULL).

It's not really necessary to configure and regenerate Makefiles in cases
like adding a new source file. The build environment and optional
features are not affected by that.

The convert and image utilities used include, but we specify the headers
by path relative to the toplevel directory for clarity. The compiler
option is not needed.

The dependencies are duplicated in many targets, but we can use the $^
variable to simplify the command line.

Reorder target dependencies:
1) target-specific objects
2) common objects
3) library objects
4) static libraries
1-3 are for faster detection of build failures, the specific objects
reflect changes to the source, but otherwise is only a cosmetic change.
The 4 is for correct order during linking, if we'd use the $^ variable.

Introduce a new macro, BTRFS_SB_OFFSET() to calculate backup superblock
offset, this is handy if one wants to initialize static array at
declaration time.

Large numbers like (1024 * 1024 * 1024) may cost reader/reviewer to
waste one second to convert to 1G.
Introduce kernel include/linux/sizes.h to replace any intermediate
number larger than 4096 (not including 4096) to SZ_*.

The regulare mkfs_btrfs does not anything special about convert and just
passes the arguments. Make that two functions.

btrfs-progs: qgroup: add sync option to 'qgroup show'

The sync call is unlikely to fail so we optimistically turn it to a
warning if that happens so we return inaccurate numbers instead of a
hard exit.

The value of sort option ('S') is not used for option letter.
Therefore, I'll change the single letter to non-character.

The 'qgroup show' command does not synchronize filesystem.
Therefore, 'qgroup show' may not display the correct value unless
synchronized with 'filesystem sync' command etc.
So add the '--sync' option so that we can choose whether or not
to synchronize when executing the command.

The assertion and warn/bug have reversed condition checks, using the
same helpers drops the exact value, so we'll print the message directly
without the helpers.
