[PATCH 1/5] perf,tools: add processor socket info in hist_entry and addr_location

[kan.liang]

From: Kan Liang <kan.liang@intel.com>

Add processor socket id info in hist_entry and addr_location.
For perf report, the socket id info is from perf.data.
For others, the socket id info is from current system.

[PATCH 4/5] perf,tools: zoom in/out for processor socket

[kan.liang]

From: Kan Liang <kan.liang@intel.com>

Currently, users can zoom in/out for threads and dso in perf top and
report. This patch extends it for socket.
'S' is the short key to zoom into current Processor Socket.

Nice feature.

Would be nice to also able to zoom into the current logical CPU.

So this works in 'perf top' only for the first screen rendering, when it
refreshes we lose the "SOCKET" header (why all caps?) and the colum
stops being %03d and instead becomes %d, I am checking now.

Patch below fix this, but we stumble in another problem, when zooming it
is not eliding the SOCKET column, i.e. if we're zooming into a column,
it will have the same value for all entries, no use in showing it, save
some columns, will check that as well.

Will fold the fixes to the patches where the problems were introduced,
the feature is cool, one more zoom! :-)

Thanks,

One more fixed, see below, now we have another, using ESC should remove
the last applied Zoom operation, just like for the other Zoom operations
(DSO, thread, etc), looking at that now.

Fixed, see below, to test, press S, then d to zoom into Socket then DSO
and then press ESC to unzoom one level (the DSO in this case) then ESC
again, to unzoom the Socket one.

If you use the left arrow key it will be equivalent to ESC, but we'll
repurpose the left/right arrows for horizontal scrolling soon.

perf tools: Add processor socket info to hist_entry and addr_location

This information will come from perf.data files of from the current
system, cached when needed, such as when the 'socket' sort order gets
introduced.

perf hists browser: Zoom in/out for processor socket

Currently, users can zoom in/out for threads and dso in 'perf top' and
'perf report'.

This patch extends it for the processor sockets.

'S' is the short key to zoom into current Processor Socket.

[ - Made it elide the Socket column when zooming into it,
    just like with the other zoom ops;
  - Make it use browser->pstack, to unzoom level by level;
  - Rename 'socket' variables to 'socket_id' to make it build on
    older systems where it shadows a global glibc declaration ]
