These uses sometimes do and sometimes don't have '\n' terminations. Make
the uses consistently use '\n' terminations and remove the newline from
the functions.

OCFS2 is often used in high-availaibility systems. However, ocfs2
converts the filesystem to read-only at the drop of the hat. This may
not be necessary, since turning the filesystem read-only would affect
other running processes as well, decreasing availability.
This attempt is to add errors=continue, which would return the EIO to
the calling process and terminate furhter processing so that the
filesystem is not corrupted further. However, the filesystem is not
converted to read-only.
As a future plan, I intend to create a small utility or extend
fsck.ocfs2 to fix small errors such as in the inode. The input to the
utility such as the inode can come from the kernel logs so we don't have
to schedule a downtime for fixing small-enough errors.
The patch changes the ocfs2_error to return an error. The error
returned depends on the mount option set. If none is set, the default
is to turn the filesystem read-only.
Perhaps errors=continue is not the best option name. Historically it is
used for making an attempt to progress in the current process itself.
Should we call it errors=eio? or errors=killproc? Suggestions/Comments
welcome.

ocfs2 sometimes needs to block signals around dlm operations, but it
currently does it with sigprocmask(). Even worse, it's checking the
error code of sigprocmask(). The in-kernel sigprocmask() can only error
if you get the SIG_* argument wrong. We don't.
Wrap the sigprocmask() calls with ocfs2_[un]block_signals(). These
functions are void, but they will BUG() if somehow sigprocmask() returns
an error.

There's no need to recalculate things via ocfs2_max_file_offset() as we've
already done that to fill s_maxbytes, so use that instead. We can also
un-export ocfs2_max_file_offset() then.

We re-use the RESVSP/UNRESVSP ioctls from xfs which allow the user to
allocate and deallocate regions to a file without zeroing data or changing
i_size.
Though renamed, the structure passed in from user is identical to struct
xfs_flock64. The three fields that are actually used right now are l_whence,
l_start and l_len.
This should get ocfs2 immediate compatibility with userspace software using
the pre-existing xfs ioctls.

Use the "format" attribute on ocfs2_error() and ocfs2_abort() so that the
compiler will warn when we get calls to those functions wrong.
