Plot CPU filtering in kernelshark has the following bug:
1) Deselect CPU A from Plot CPU list
2) Plot gets updated with no CPU A
3) Deselect CPU B
4) Plot continues to have CPU B
This is due to a bug in graph_plot_cpus_update_callback(),
which seems to be checking old_all_cpus != new_all_cpus before doing any
update. This condition is true on 1, but false on 2.
Removing that check fixes the problem.
Tested:
Above sequence now does expected filtering.

The button "All CPUs" in CPU filter dialog allows setting of all CPUs
but doesn't clear CPUs when it is unchecked. Make sure that when the
"All CPUs" button is unchecked, all the CPUs get unchecked.
Tested: In kernelshark, go to Filter->list CPUs and uncheck "All CPUs"
button. All the CPUs should be unchecked at that point.

The sched tracepoint names are unique and so there is no need to check
for the subsystem name while looking up the event ID.
This helps kernel shark display the graphs correctly for trace.dat files
generated from trace collection mechanisms that don't record the subsystem.

"width" and "height" were swapped, causing the vertical marker and cursor lines
to be drawn with the wrong height.
