reuse in other binaries that require counter list filtering.

Add command line option --counters XXX,YYY to specify a comma
separated list of counter names to be displayed. The counter names
have to match exactly beside case sensitivity.
All counters not listed in the list specified by the --counters option
are not shown.

Add a command line flag '-a' to include the counter set values
from each individual CPU. Up to now only the total sum from
all CPUs was printed.

Add command line flag -d to display the counter value in form of
a delta value. This format shows the increase of that counter value
compared to the previous value.
The first line is the base for the delta calculation and always
shows 'Total'. The remaining lines show 'Delta' in the third
column.

Add command line flag -s to display the counter name in an
abbreviated form. The abbreviated form is a character for the
PAI counter set followed by a number.
PAI crypto counter set is abbreviated to 'C'.
PAI NNPA counter set is abbreviated to 'N'.
The number refers to the defined counter number ranging from
1 to X.

Add command line flags -i (read interval) and -l (loops) to
show the counter values for the specified number of iterations.
The CPUs to read the counter values from can be specified
on the command line. If none are specified, all online CPUs
are used.
For example the command '# lspai -l 2 -i 10 -t nnpa'
displays all PAI NNPA counter values two times with 10 second
interval.
