list_journal can print the entire contents of the journal, and non-dirty
entries don't get validated, so we have to account for that.

This has been leading to too many people taking metadata dumps of rw
mounted filesystems.

It was forcing human readable units even without the -h flag,
so use the functions that respect that configuration.

The splice fd might have been closed, and a double-close here shouldn't
be a concern because we're not doing any interesting multithreaded
things and it's local to this function.

Add an option for controlling whether we create a third redundant
superblock at the end of the device.
For image files that are going to immediately be resized, we want to
skip this.

this allows O_CREAT to be passed through, for the new image creation

Non power of two bucket sizes are allowed - but not preferred.
We were accidentally picking bucket sizes that weren't blocksize
aligned - ouch.

- we can now correctly open by parsing sysfs, instead of falling back to
reading the superblock and grabbing the UUID
- non-UUID filesystem names now work

With single device mode we won't always show up in sysfs by UUID, but
the new VFS ioctl handles this nicely.

Add a helper to check for close errrors - especially bad file
descriptors, that can be a fun source of heisenbugs.

This needed an access() check, like the other uses, instead of exiting
if it can't be read.
Factor out a small common helper for this.

We don't want users hitting this accidentally, and if needed for some
strange reason (it shouldn't be), it can still be specified via -o.

Migrate now works: there is an inconsequential free space inconsistency
after marking the new superblock (in migrate_superblock), which we're
hacking around with a fsck.

bucket size now takes into account system memory and amount of memory
required to fsck: on very large filesystems it will automatically scale
up bucket size to ensure we can fsck.

More work to regularize device options, with common command line
parsing - like other options.
This fixes an assortment of little nits: buggyness with the discard
option, device state (and others) can now be specied at device add time,
and is a decent cleanup.

-a is used when called from system to mean "automatic invocation, run
check only if you think you need it".
Since we have self healing and online fsck, we never need run fsck
automatically at boot time.
