Karel Zak 33f2d6b84d btrfs-progs: autoconf: use standard PACKAGE_* macros
- use standard PACKAGE_{NAME,VERSION,STRING,URL,...} autoconf macros
  rather than homemade BTRFS_BUILD_VERSION

- don't #include version.h, now the file is necessary for library API only

Note that "btrfs version" returns "btrfs-progs <version>" instead of
the original confusing "btrfs <version>".

Dimitri John Ledkov e69e015634 btrfs-progs: drop feature defines from C files, in favour of CFLAGS defines
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.

Josef Bacik 2d80d0d645 Btrfs-progs: add a message to know zero log ran successfully
If there are errors when opening the fs because of PARTIAL we could think that
the zero-log didn't actually work.  Add a printf so we know that it was
successfull.  Thanks,

Gui Hecheng f1672e50c7 btrfs-progs: use check_argc_* to check arg number for all tools
Since this patch:
	btrfs-progs: move the check_argc_* functions into utils.c

All tools including the independent tools(e.g. btrfs-image, btrfs-convert)
can share the convenience of the check_argc_* functions, so this patch
adopt the argc check functions globally.

Josef Bacik 4735d0bb82 Btrfs-progs: rework open_ctree to take flags, add a new one V2
So I needed to add a flag to not try to read block groups when doing
--init-extent-tree since we could hang there, but that meant adding a whole
other 0/1 type flag to open_ctree_fs_info.  So instead I've converted it all
over to using a flags setting and added the flag that I needed.  This has been
tested with xfstests and make test.  Thanks,

David Sterba dd21bc16ad btrfs-progs: separate super_copy out of fs_info
Allocate fs_info::super_copy dynamically of full BTRFS_SUPER_INFO_SIZE
and use it directly for saving superblock to disk.

This fixes incorrect superblock checksum after mkfs.

Chris Mason 6da41f2a74 btrfs-progs: make sure btrfs-zero-log writes something
The close_ctree code does a check to see if the FS has
changed before it does any IO.  This forces the commit.
