ocfs2ne: Add tunefs_dlm_[un]lock()
Because we have a master ocfs2_filesys object that access the dlm, but
sub-objects that are passed to the operations, we need to have online
operations access teh master object when locking the cluster.

ocfs2ne: Create a shared filesystem state object.
The first caller to tunefs_open() will allocate a state object to
describe what tunefs has for the filesystem. This includes the online
ioctl(2) fd and any local mount O_EXCL fds. Later, we'll add cluster
locking info.

ocfs2ne: Whoops, clear the allowed errors from tunefs_open()
tunefs_open() has a couple special error codes to tell us we need to
behave a certain way (eg, PERFORM_ONLINE). Once we've handled that
behavior, we need to clear the error so later code doesn't think
something broke.

ocfs2ne: Connect up resize units.
ocfs2ne_resize_volume can now handle a new size in blocks, clusters, or
bytes. This is accomplished by prefixing the size with the unit.
ocfs2ne uses the argument argument of -S to determine this.

tunefs.ocfs2: Add an interactive function to libtunefs.
While tunefs methods just perform their operations by default, sometimes
people want to select the operations interactively. The -i option is
added, and the tunefs_interact() function uses it. Methods can now call
tunefs_interact() before they do anything. If it returns true, they
proceed. If it returns false, they exit cleanly.
tunefs_interact() always returns true when in non-interactive mode (-i
was not specified).

tunefs.ocfs2: Add global bitmap checking to libtunefs.
In theory, a clean filesystem has a consistent global bitmap. We have
flags like RESIZE_INPROG and TUNEFS_INPROG to force fsck.
The old tunefs.ocfs2 also scans the global bitmap for any operation that
requires operation. It's a reasonably fast extra sanity check. Let's
port that to tunefs_open() with the flag TUNEFS_FLAG_ALLOCATION.

libocfs2: Move printable feature flags to feature_string.c
We currently have pretty-print strings for each feature flag in
ocfs2/ocfs2.h It's just a bunch of defines, but it was good to have the
strings defined in one place.
However, we weren't even using them correctly. tunefs.ocfs2/query.c
used them, but debugfs.ocfs2/utils.c had its own strings. They didn't
even match.
In the end, we have a place for this sort of thing:
libocfs2/feature_string.c. This patch adds the entire feature<->string
mapping, including tunefs INPROG flags. The functions
ocfs2_snprint_feature_flags() and ocfs2_snprint_tunefs_flags() have the
capability of using the strings to print out a feature set.
The strings are removed from ocfs2/ocfs2.h. tunefs.ocfs2/query.c and
debugfs.ocfs2/utils.c are changed to use the ocfs2_snprint_*_flags()
API.
As a bonus, tunefs.ocfs2 no longer needs glib.
While were there, a bug in tunefs.ocfs2/query.c is fixed. The print
format wasn't properly terminated, so we switch to ocfs2_malloc0() to
ensure this.

libocfs2: Add ocfs2_feature_foreach()
The ocfs2_parse_feature() function will include dependent features when
used. For example, if you ask it to parse "unwritten", it will return a
feature set that includes both unwritten extents and sparse files,
because unwritten extents depends on sparse files. The same is true in
reverse. If you ask it "nosparse", it will return a reverse set that
includes sparse files and every thing that depends on it.
However, the caller has no way of knowing which feature needs to be
added or removed first. A naively ordered program might try to add
unwritten extents before sparse files. That will fail.
We introduce ocfs2_feature_foreach() and
ocfs2_feature_reverse_foreach(). These functions take a feature set and
iterate over it, calling a supplied callback once per feature. The
former function does it in "set" order, the latter obviously in "clear"
or reverse order.

libocfs2: Clearing features should clear their dependancies.
The ocfs2_parse_feature() API was not symmetric. If asked to set a
feature, it would set the feature and its dependencies. However, when
asked to clear a feature, it would not clear the other features that
depended on it. Thus, a caller looking at the list of features to clear
would have to know the reverse dependencies as well.
This change modifies ocfs2_parse_feature() to include the reverse
dependencies. In addition, ocfs2_merge_feature_with_level() takes
advantage of the change to become simpler.
Finally, tunefs.ocfs2 now expects the reverse dependencies. Instead of
adding them by hand, it makes sure they exist and behaves appropriately.
