Btrfs-progs: fix a bug of converting sparse ext2/3/4

When converting a sparse ext* filesystem, btrfs-convert adds checksum extents
for empty extents, whose disk_bytenr = 0, and this can end up with some weird
problems, one of them is the failure of reading free space cache inode on
mounting converted btrfs.

The fix is simple, just to skip making checksum on empty extents.

btrfs-progs: fix return value problem for btrfs sub show

If you exec:
	# btrfs sub show <dir>	<== non-subvolume dir
The cmd print error messages as expected, but returns 0.
By convetion, it should return non-zero and we should explicitly
set it before it goto out.

With other pieces adopted:
1) removed a unnecessary return value set -EINVAL
2) fixed another code branch which may return 0 upon error.
3) with 2) applied, the ret = 0 follows can be removed

btrfs-progs: apply realpath for btrfs fi show when mount point is given

For now,
	# btrfs fi show /mnt/btrfs
gives info correctly, while
	# btrfs fi show /mnt/btrfs/
gives nothing.

This implies that the @realpath() function should be applied to
unify the behavior.

Made a more clear comment right above the call as well.

Btrfs-progs: add_refs_for_implied: Use root_id instead of root_bytenr.

resolve_one_root() returns the objectid of a tree rather than the logical
address of the root node. Hence using root_bytenr is misleading. Fix this.

btrfs-progs: print root dir verbose error in fsck

Before this patch, when btrfsck found an error in root dir, it will only
output the following message "root %llu root dir %llu error" without any
detailed error.

Just add print_inode_error() to print out the whole error.

btrfs-progs: add ./configure script

Add ./autogen.sh script, you have to use it after "git clone/clean" to
generate ./configure from configure.ac.

Modify version.sh to be usable from the configure script.

The patch also renames Makefile to Makefile.in, but does NOT change
anything in the file.

btrfs-progs: use config.h

- the header file is generated by ./configure, the standard autotools
  way is to use -include config.h on compiler command line rather than
  include the file directly from code

- remove _GNU_SOURCE from code, the macros is already defined in config.h
  by AC_USE_SYSTEM_EXTENSIONS autoconf macro

btrfs-progs: 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
