cpumf/lswhc: Add short names to lshwc output

Browse Source 
Add option -s or --short to display the header using a short
counter name. With this option the counter symbol names, which can be
very long as in IDCW_ON_DRAWER_DRAWER_HIT are replaced by a shorter
name. That name consists of an abbrevation for the counter set
this counter belongs to and the counter number in that set.

The abbrevations are:
B --> Basic counter set
P --> Problem state counter set
C --> Crypto counter set
E --> Extended counter set
M --> MT_Diagnostic counter set
U --> Undefined counter.

Display E165 for counter name IDCW_ON_DRAWER_DRAWER_HIT
which is counter number 165 from the extended counter set.
