fix a bunch of issues I noticed along the way after a hint from Eli Schwartz.

fstab.5 mount.8: add note about field separator
The value of the mount option X-mount.idmap= can contain spaces as
separators between mappings. Unfortunately, this conflicts with the
fstab format where fields are separated by spaces. Using quotes does
not solve this issue because fields are separated before they are
parsed.
This limitation of the fstab parser within libmount is due to backward
compatibility. The fstab format is a de-facto standard and is parsed
by many tools and libraries, including third-party shell scripts. It
would not be practical to introduce any improvements in libmount that
would make fstabs unparseable in other places.
Users must understand that in-field spaces must be escaped by \040.
For example, X-mount.idmap="0:0:1\040500:1000:1".

libmount: exec mount helpers with posixly correct argument order
This improves compatibility with non-gnu userspaces.
On systems where the libc provides posix getopt instead of gnu getopt,
mount helpers which use getopt to parse arguments will not parse
options which appear after non-option arguments. This patch ensures
mount/unmount work as expected in this situation.
mount: fix expected argument order for mount helpers in tests
Reads of ext superblocks can race with updates. If libblkid observes a
checksum mismatch, re-read the superblock with O_DIRECT in order to get
a consistent view of its contents. Only if the O_DIRECT read fails the
checksum should it be reported to have failed.
This fixes a problem where devices that were named by filesystem label
failed to be found when systemd attempted to mount them on boot. The
problem was caused by systemd-udevd using libblkid. If a read of a
superblock resulted in a checksum mismatch, udev will remove the
by-label links which result in the mount call failing to find the
device. The checksum mismatch that was triggering the problem was
spurious, and when we use O_DIRECT, or even perform a subsequent retry,
the superblock is correctly read. This resulted in a failure to mount
/boot in one out of every 2,000 or so attempts in our environment.
e2fsprogs fixed[1] an identical version of this bug that afflicted
resize2fs during online grow operations when run from cloud-init. The
fix there was also to use O_DIRECT in order to read the superblock.
This patch uses a similar approach: read the superblock with O_DIRECT in
the case where a bad checksum is detected.

Bitfields have their uses, but the uses here didn't make any sense.
Code generated to read or write bitfields is more complicated (and
slower) because, well, the bits need to be manipulated with special
instructions. So bitfields should be used when we have a structure
that is repeated hundreds or thousands of times in memory and those
saving are higher than the cost of having more complicated code. This
can happen for example in the kernel code. But the code here has
structures that are instantiated once or or at most few times.
In addition, a bitfield often does not save any memory because of
alignment requirements. In the majority of cases modified here, the
bitfield was the last field in a structure, so no memory savings were
made.
(To be clear: those small savings are not particularly important. The
motivation for this patch is to eradicate the antipattern of making
things more complicated without any benefit.)
Currently, additional locations (such as /run or /usr/lib) are only
read if /etc/issue does not exist. This behavior makes it difficult to use
local settings (/etc) together with generated (/run) and distribution-specific
(/usr/lib) files. Let's read all the locations.
If the output of issue files is unwanted, the option --noissue can be
used, or the default locations can be ignored by using --issue-file
<list>.
