tunefs rework: Link ocfs2ne into the build.
ocfs2ne is now built alongside tunefs.ocfs2. They should do identical
things.

tunefs rework: Add ocfs2ne.c
This is the master ocfs2ne program which will become tunefs.ocfs2. It
handles processing all arguments and locking down the filesystem before
calling the selected operations in turn.
This is the culmination of a rework of tunefs.ocfs2. There were these
major goals:
1) All operations would be independent. They do not need to know what
else is running. They live in a separate C file and can be tested by
themselves.
2) All operation can run in the same invocation of tunefs. The master
program makes sure the appropriate locks are taken and that each
operation is given a clean filesystem to work with.
3) The actual working code should move over with only small changes.
The code that performs an operation is largely unchanged. Output
functions are different, and a couple common bits of code moved into
libocfs2ne.

tunefs rework: Add the libocfs2ne sources.
The libocfs2ne library contains the routines shared by all ocfs2ne
methods and programs. This includes opening and closing the filesystem,
locking the cluster, managing online operations, and interacting with
the user.

libocfs2: ocfs2_parse_feature() checks for conflicts too.
We don't allow --fs-features options to conflict. That is,
"sparse,nosparse" is illegal, whether explicit or from a dependency.
Rather than have subprograms check this themselves, do it in
feature_string.c

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.

commit 50e5660ea3e18857077be8a89004022f736dd50c

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.
