lscpu: add human readable extended cpu table output
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.
