like adding a new source file. The build environment and optional

glibc 2.10+ (5+ years old) enables all the desired features:
_XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a
single _GNU_SOURCE define in the makefile alone. For portability to
other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also
defined.
This also resolves Debian bug report filed by Michael Tautschnig -
"Inconsistent use of _XOPEN_SOURCE results in conflicting
declarations". Whilst I was not able to reproduce the results, the
reported fact is that _XOPEN_SOURCE set to 500 in one set of files
(e.g. cmds-filesystem.c) generates/defines different struct stat from
other files (cmds-replace.c).
This patch thus cleans up all feature defines, and sets them at a
consistent level.

This patch adds some functions to manage the printing of the data in
tabular format.
The function
struct string_table *table_create(int columns, int rows)
creates an (empty) table.
The functions
char *table_printf(struct string_table *tab, int column,
int row, char *fmt, ...)
char *table_vprintf(struct string_table *tab, int column,
int row, char *fmt, va_list ap)
populate the table with text. To align the text to the left, the text
shall be prefixed with '<', otherwise the text shall be prefixed by a
'>'. If the first character is a '=', the the text is replace by a
sequence of '=' to fill the column width.
The function
void table_free(struct string_table *)
frees all the data associated to the table.
The function
void table_dump(struct string_table *tab)
prints the table on stdout.

This commit improves the static-only building of btrfs-progs, and adds
support for installing the static only tools:
- It now ensures that all programs are built statically, not only a
small subset of them, by defining 'progs_static' from the existing
'progs' variable.
- It changes the order of libraries in the btrfs-%.static rule so
that -lpthread (part of STATIC_LIBS) appears *after* the '$($(subst
-,_,$(subst .static,,$@)-libs))' logic, which brings in
-lcom_err. This is needed because libcom_err.a uses the semaphore
functions, which are available in the pthread library.
- Adds the necessary rules to generate the btrfsck.static link and
btrfstune.static binary.
- Adds an 'install-static' target to install the static
binaries. Note that they are renamed to not carry a '.static'
suffix.

This patch adds functionality (in qgroup-verify.c) to compute bytecounts in
subvolume quota groups. The original groups are read in and stored in memory
so that after we compute our own bytecounts, we can compare them with those
on disk. A print function is provided to do this comparison and show the
results on the console.
A 'qgroup check' pass is added to btrfsck. If any subvolume quota groups
differ from what we compute, the differences for them are printed. We also
provide an option '--qgroup-report' which will run only the quota check code
and print a report on all quota groups. Other than making it possible to
verify that our qgroup changes work correctly, this mode can also be used in
xfstests for automated checking after qgroup tests.
This patch does not address the following:
- compressed counts are identical to non compressed, because kernel doesn't
make the distinction yet. Adding the code to verify compressed counts
shouldn't be hard at all though once kernel can do this.
- It is only concerned with subvolume quota groups (like most of
btrfs-progs).

Until now if one of device's first superblock is corrupt,btrfs will
fail to mount. Luckily, btrfs have at least two superblocks for
every disk.
In theory, if silent corrupting happens when we are writting superblocks
into disk, we must hold at least one good superblock.
One side effect is that user must gurantee that the disk must be
a btrfs disk. Otherwise, this tool may destroy other fs.(This is also
reason why btrfs only use first superblock in every disk to mount)
This little program will try to correct bad superblocks from
good superblocks with max generation.
There will be five kinds of return values:
0: all supers are valid, no need to recover
1: usage or syntax error
2: recover all bad superblocks successfully
3: fail to recover bad superblocks
4: abort to recover bad superblocks

There were a few problems that were breaking sparse checking:
- We were defining CHECK_ENDIAN late in the environment, after
linux/fs.h has been included which defines __force and __bitwise in
confusing ways that conflict with ours. Define it up with __CHECKER__
so that linux/fs.h and our copy are acting on the same input.
- We had manually set a few of gcc's internal defines to give to sparse.
It's easier to just ask gcc for all the defines it sets and hand those
to sparse.
- We weren't passing the same *FLAGS to sparse as we were to CC.
- glibc has so many errors with FORTIFY turned on that sparse gives up
and doesn't show us any errors from our code. It's a questionable
hack to always turn on FORTIFY ourselves, so we'll just not do that
when building with sparse.
And add a nice '[SP]' quiet output line for sparse checks.
