- 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>".

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.

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,

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.

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,

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.

The close_ctree code does a check to see if the FS has
changed before it does any IO. This forces the commit.
