* ext2fs_allocate_block_bitmap() now allocates a bitmap with cluster

  newly added function, ext2fs_allocate_subcluster_bitmap() allocates
  a bitmap with block granularity (even for bigalloc file systems).
  The newly added function ext2fs_get_bitmap_granularity() will return
  the number of bits (log2) of the granularity used by the bitmap.

* The ext2fs_{mark,unmark,test}_block_bitmap2() functions will shift
  their passed-in argument by log2(cluster_ganularity) bits right.
  This means that the arguments for the single-argument bitmap
  functions will be interpreted with block granluarity, since this
  minimizes code changes in the rest of the code base.

* The ext2fs_{get,set}_block_bitmap_range() functions will interpret
  their arguments in cluster granularity.  This is a bit inconsistent,
  but the caller of those functions will need to be taught about the

mke2fs: Display progress report during the device discard

For some time now we are doing initial discard of the device prior to
filesystem creation. However, there is no feedback for the user and
hence on some devices with slow TRIM implementation it may appear that
mke2fs is stuck.

This commit introduce new function mke2fs_discard_device(), which is a
wrapper for io_channel_discard(). The discard is done in chunks of
2GB, which seems reasonably well for both slow and fast devices, and
discard progress is reported back to the user.

I gave up on doing fancy things like align discard according to
discard_alignment, checking for discard granularity and computing
estimate time. First of all, because it would require either new ioctl
to retrieve those information or use of libudev library, none of it
seems to be worth it. Regarding discard_granularity, I doubt there is
any sane device with discard granularity that big it would affect this.

create a resize inode with 0 reserved blocks, and mark the resize_inode
feature.

A subsequent slight downward resize of the filesystem would remove
the resize inode, making any further offline resizing impossible.

This is especially odd in light of the fact that a large downward
resize (say, to 8T) will actually add blocks to the resize inode -
so a small resize removes it, a large resize expands it ...

commit 8ade268cf2fde8629b51bfd1c044a83db88234cd had added this:

  If the filesystem is grown to the point where the resize_inode is no
  longer needed, clean it up properly so e2fsck doesn't have to.

but, it seems e2fsck does not care about this situation, either.

So, simply leave the resize_inode intact in this case, and everything
seems to be happy.

not loff_t (even though the system call interface is 64-bit clean).
This causes e4defrag to fail on files greater than 2GB.  Fix this by
trying to use fallocate64(), and using the hard-coded syscall if it
does not exist.
