rename: make --no-act to imply --verbose
It is reasonable to assume use of --no-act means one wants to always see
what would have happen if rename is done. To say same slightly differently,
if there is sn use case for silent rename --no-act run I cannot think one.

libblkid: udf: Change algorithm for reporting UUID
Ensure that reported UUID always contains only lowercase hexadecimal digits
and is always 16 characters length, padded with zero digits.
Volume Set Identifier is converted to UTF-8 before generating UUID from it.
As it could potentially contain any Unicode character. So correctly handle
both 8bit and 16bit OSTA Compressed Unicode encodings.
Disks which have only lowercase hexadecimal digits in Volume Set Identifier
would have same UUID as before this patch.

libblkid: udf: Correctly handle UDF strings encoded in 8bit OSTA Compressed Unicode
String encoded in 8bit OSTA Compressed Unicode contains one Unicode
codepoint per 8bits. Maximal Unicode codepoint is U+FF. Which effectively
means that it is equivalent to Latin1 encoding.
Before this patch libblkid copied raw 8bit OSTA Compressed Unicode from
disk and treated it as UTF-8. It worked fine just for UTF-8 invariants,
other characters were incorrectly encoded. This patch fixes this problem.
Note that processing UUID is not fixed in this patch.

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).

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.

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.
