64 bit block pointers, extended attribute storage, and a few
other things.
This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

failures as well as successes when a run of clean_all_inodes completes.
Explicitly cast to off_t in get_dinode and get_rawblock, to make sure we
read the right block.
a potential problem with cleaning fragments at all.
Better sanity checks when selecting files to coalesce; in particular don't
shift too far left when comparing the number of discontinuities to the log2
of the number of total blocks.
Better log messages: note beginning of coalescing correctly; also take
the log message from add_segment out of "if (debug)" for symmetry with the
"finished segment" message.
Use lfs_bmapv to find the inode, rather than looking it up manually in
the ifile; this should give more up-to-date information, since trolling
through every inode in the fs could take some time.
be digging itself deeper into a hole, it forks off a subprocess
that locates files with too many discontinuities and rewrites them, if
there is enough room.
Optionally the user can manually coaleasce files by running with "-c".
The recent change to lfs_markv is required for the coalescer to do anything.
All of "digging itself deeper", "too many discontinuities", and "enough room"
need to be better defined.
