We want to address the case that we have printed the last useful
stats line already within the loop. Avoiding an additional line
"Discarded 0 bytes ..." at the end.
Note there is a behavior change now for the edge cases "-v -l 0" and
"-v -o blksize" where we don't print any stats line anymore. But actually
it's correct, we never make any BLKDISCARD syscall with zero range.
Perhaps we should return error in these cases to help people who always
want to parse stats output on success.

We will see if this makes our "--step" tests reliable.

xz decompression creates sparse files if possible. This saves about 1G
disk space in build directory and a lot I/O and time.
BTW regarding compatibility ... CentOS 7 is the first system I've met
which does not install bzip2 but xz only by default.

lscpu currently prints information for CPUs configured in the system.
In case of KVM or other virtualized guest operating systems, this
refers to the virtual system, and bears no relation to the physical
topology of the system.
It would be useful if lscpu could also display the physical topology
info when available:
$ ./lscpu
Architecture: ppc64le
Byte Order: Little Endian
CPU(s): 16
On-line CPU(s) list: 0-15
Thread(s) per core: 1
Core(s) per socket: 1
Socket(s): 16
NUMA node(s): 1
Model: IBM pSeries (emulated by qemu)
Hypervisor vendor: KVM
Virtualization type: para
L1d cache: 64K
L1i cache: 32K
NUMA node0 CPU(s): 0-15
Physical sockets: 2 <<< New
Physical chips: 4 <<< New
Physical cores/chip: 4 <<< New
For now, physical topology information is available on platforms that
support the following RTAS (Real time abstraction service) call provided
by librtas:
rtas_get_sysparm(PROCESSOR_MODULE_INFO).
Currently this call is available to the PowerVM (pHYP) guests on PowerPC.
With a patch propoosed to PowerKVM, this RTAS call would also be available
to PowerKVM guests.
Based on input from Nishanth Aravamudan and Karel Zak.

* more verbose output about columns width counting
* strlen_line() does not care about space between columns and extra
tree ASCII art. Let's assume that all termwith is possible to use
for this extra stuff, it means that maximal buffer size is
biggest_line + termwidth.

agetty uses NETLINK_ROUTE to be notified about network interface
changes. Unfortunately, the code that monitor the netlink FD does not
increment number of the monitored file descriptors when call
select(2), so the netlink notifications are invisible for agetty.
