Use "[u]" instead of "[uninit]" and limit the amount of detail printed
for the extent tree blocks, so it is more similar to the format used
for direct/indirect mapped inodes.

After cleaning up ext2fs_bg_flag_set() and ext2fs_bg_flag_clear(),

Extend the stat command to display more detailed extent information if
the file uses extent mapping instead of displaying the block map using
the block_iterate funtion.
Add the command dump_extents which displays even more detailed
information about an inode's extent tree.
This commit is an extension of a patch from Curt Wohlgemuth.

This is a regression from commit
8fdf29117f, which attempts to access
current_fs via a feature check before we check that it's open.
Just moving the feature check below the open check should fix it.

Print out the currently supported features of e2fsprogs/libext2fs
via a new "debugfs supported_features" command. This helps scripts
to know whether it is possible to try and enable specific features

Taking a cue from getfattr... if a string is "mostly"
printable characters, go ahead & print as a string,
and escape what's left over.
so we get:
Extended attributes stored in inode body:
selinux = "system_u:object_r:root_t:s0\000" (28)
instead of:
Extended attributes stored in inode body:
selinux = "73 79 73 74 65 6d 5f 75 3a 6f 62 6a 65 63 74 5f 72 3a 72 6f 6f 74 5f 74 3a 73 30 00 " (28)
(selinux includes the trailing null in "len" so it
never prints as a string today)

This change allows debugfs to be reused as the base for e2fsprogs
internal test programs, by linking debugfs object files with
additional object file(s) that define additional commands. The test
program's object file(s) should define their own comand table, and
define the symbol extra_cmds to be a pointer to the ss_request_table.
In addition, the symbol debug_prog_name can be used to override the
name of the program printed in the version banner and in the ss
prompt.

When recovering a large number of deleted files, linking the undeleted
inodes to directories may require a directory to be expanded. This
could allocate a block that that had been used by one of the
yet-to-be-undeleted files. So the 'undel' command been enhanced to
allow the destination pathname to be optional. This will allow the
cautious user to undelete all of the inodes without specifying a
destination pathname, and then either use debugfs's link command to
add hard links, or use e2fsck to link all of the recovered files to
the lost+found directory.

Mke2fs is supposed to set the uid/gid ownership of the root directory when
a non-rooot user creates the filesystem. This wasn't working correctly
if the uid/gid was > 16 bits. In additional, debugfs wasn't displaying
large uid/gid's correctly. This patch fixes these two programs.

This feature is initially intended for testing purposes; it allows an
ext2/ext3 developer to create very large filesystems using sparse files
where most of the block groups are not initialized and so do not require
much disk space. Eventually it could be used as a way of speeding up
mke2fs and e2fsck for large filesystem, but that would be best done by
adding an RO_COMPAT extension to the filesystem to allow the inode table
to be lazily initialized on a per-block basis, instead of being entirely initialized
or entirely unused on a per-blockgroup basis.
