This commit will allow user to create quickly plenty of ipc
resources. Earlier the line bellow gave no satisfaction.

An --all option will remove all ipc entries. The option takes
optional resource argument, which limits the removal to be
applied only the given resource entries.

Two includes added & a sort to alphabetical order.
ipcs.c should add these lines:
#include <features.h> // for __GLIBC__
#include <stddef.h> // for size_t

Previously for instance lack of memory space caused unknown
reason to be printed, and ipcrm tried to continue.

With long options usage function had to be changed. The change
also takes libc error printing facilities to use, primarily to
get rid of execname & progname variables.

Checking same return value twice does not make command any
better. Secondly the program_invocation_short_name is known to
work, so global progname variable does not add anything extra.

Reduce code duplication and print better error message if an
unsupported cpu number was passed.

The current cpulist_parse() function ignores extra non-parsable characters at
the end of the to be parsed cpu list string. E.g. it would accept something
like "0bla" and just set bit 0 in the cpu set. Since such a string is invalid
implement stricter parsing that makes sure that everything of the string has
been succesfully parsed.

If cpulist_parse() gets passed a cpu list with a stride value of 0 it will be
stuck in an endless loop. E.g. the following cpu list will cause an endless
loop: "0-2:0". Fix this by causing a parse error if the stride value is 0.

The opening and closing braces for two following if statements within
cpulist_parse() are placed in an odd manner.
Just fix this to prevent broken code in the future.

The comments for cpumask_parse() and cpulist_parse() each describe
the wrong function. Just exchange the comments.

Some vendors have several hypervisors. Therefore it makes sense to not only
print out the hypervisor vendor but also the name of the hypervisor.

The parsable output includes only lines of online CPUs. To also include
lines for all offline CPUs the "--all" option can be specified.

lscpu only prints lines for online CPUs. At least for the human readable
list the offline CPUs are of interest as well. In order to distinguish
between online and offline CPUs introduce the "Online" column.
By default the human readable output now displays online and offline CPUs.
The parsable output is not changed. It will print only lines for online
CPUs as it used to do.

CPUs may be in a configured or deconfigured state depending if the CPU resource
may be used by the guest. If a CPU is in configured state the guest may use it
(i.e. set it online). It it is in deconfigured state it cannot use it before
changing its state to configured. Display this CPU attribute as well.

Based on patch from Heiko Carstens <heiko.carstens@de.ibm.com>:
lscpu currently only supports a parsable output which contains a row for
each cpu and its attributes. This output contains only comas as separators
and is hard to read for humans.
Therefore add a new option "-e | --extended" which outputs the rows in a
much more readable (and non-parsable) form. Just like for the -p option a
list of columns can be specified that shall be included in the output.
By default this option will print all columns that contain data.

First check path before accessing files to be sure they actually exist. This is
necessary when also informations for offline CPUs will be printed. Since we do
not necessarily know if "cpu is offline" means the same as "path does not
exist" just check for it.

Simplify the logic to "always print a ',' for each cache except if it is the
last one. This is also a preparation patch for printing the cache column for
offline CPUs where it would print one colon too much because of the current
logic.

The extended parsable output prints a colon instead of comma between each
item. The case where a CPU doesn't belong to any cache was not converted.
Just fix this.

Fix typo where the comma operator has been introduced.
Use a semicolon instead so we end up with simple assignment expressions.
