Karel Zak f9ac021032 lscpu: remove obsolete code 
This is the first step in conversion from old lscpu to the new code.
The patch removes obsolete code from lscpu.c and lscpu.h. The old
output code in lscpu.c is temporary disabled by #ifdef due to
incompatibility between old and new internal APIs -- this will be
changed later by small steps to make all all the changes review-able.

Karel Zak fa6a21bf63 lscpu: calculate threads number from type specific values 
Don't use global CPU masks (like "online" or "present") to
calculate type specific number of threads due systems with
mixed CPU types.

It's also necessary to check all thread_siblings maps to get the
highest number, because some threads (CPUs) may be disables, for
example old lscpu calculates number of threads from the cpu0 and
if you disable cpu0's sibling (cpu4):

	CPU(s):                          8
	On-line CPU(s) list:             0-7
	Thread(s) per core:              2        <---
	Core(s) per socket:              4
	Socket(s):                       1

 # chcpu --disable 4
 CPU 4 disabled

	CPU(s):                          8
	On-line CPU(s) list:             0-3,5-7
	Off-line CPU(s) list:            4
	Thread(s) per core:              1        <--- !
	Core(s) per socket:              4
	Socket(s):                       1

because 'thread_siblings' contains only one thread for cpu0:

 # cat /sys/devices/system/cpu/cpu{0,1,2,3,4,5,6,7}/topology/thread_siblings_list
 0
 1,5
 2,6
 3,7
 cat: /sys/devices/system/cpu/cpu4/topology/thread_siblings_list: No such file or directory
 1,5
 2,6
 3,7
