lscpu: reuse the same buffer
Now we use libsmartcols for the default output and all is allocated in
the smartcols table. So, we can reuse the same buffer for all
sprintf/scanf calls.
lscpu: Read available CPUs max and min frequencies
Problem:"lscpu frequency-info" command was always reading CPU0
max and min frequencies. If CPU0 is guarded or offline then it used to
display max and min frequencies as NULL.
This patch will read overall CPU max and min frequencies.

tests: Add UDF CD-ROM hybrid image (ISO+Joliet+UDF) created by Nero 6
This image was created by Nero Burning ROM version 6 via option CD-ROM
(UDF/ISO) with UDF version 2.01 and enabled ISO Joliet extension. Moreover
for testing purposes it has set custom Disc label (and also every other
identifier) which is different for ISO, Joiliet and UDF part. It contains
ISO/Joliet/UDF string prefix to distinguish between them.
So reading this image as basic ISO would produce different label as when
reading it as ISO with Joliet image and also different as UDF image.
UUID is different due to fact that ISO image does not have UUID and
libblkid generate one from compilation date. Plus "Joliet Extension" in UDF
context does not make sense.
Reporting meaningless ID_FS_LABEL=UDF_Volume written in that commit was
caused by reading wrong value for UDF label and it was fixed in commit 2f2730bc77c972d613cfec421468c84f15749708.
So after this revert blkid reports for UDF filesystems label of UDF
filesystem and not label of ISO (if present) like other systems. In most
cases UDF and ISO labels are same (sometimes just one is upper case).

sulogin: reduce vulnerability surface
Hopefully these changes are unreachable code, but better safe than sorry
when dealing with setuid root code that is installed everywhere. Quite
obviously the introduced abort() calls protect from impossible inputs.
Secondly set all possible data to be read-only in attempt to make it more
difficult to alter anything at all.

blkid: add long options
This change attempts to make tab completion more reasonable by alloging
memorizable option names. That also has positive impact to manual page, in
which referrals to other options are now easier to understand.
All short options are kept exactly as they were to avoid ABI breakage. The
only exception is -f option that getopt(3) recognized, but was not found
from anywhere else. The -f has been part of blkid since the initial commit.

lsipc: fix options parsing and sync with man page
Option --pid was never implemented so remove it from struct options and
manual page. Interestingly this option was not in usage(). Short option
string had 'u' that has never appear anywhere else, so it is also removed.
Finally add options --bytes and --numeric-perms to manual page.
