perf hists browser: Warn about lost events
...
Just like the old perf top --tui and the --stdio version.
But because we have the initial menu to choose which event to show in a
session with multiple events we can see how many chunks were lost in
each of the event types, clarifying which events are being affected the
most.

perf hists browser: Recalculate browser pointers after resort/decay
...
In browsers that access dynamic underlying data structures, like in the
hists browser and its hist_entry rb_tree, we need to revalidate any
reference to the underlying data structure, because they can have gone
away, decayed.
This fixes a problem where after a while the top entries get behind the
top of the screen, i.e. the top_idx stays at 0, which means it is at the
first entry in the rb_tree when in fact it wasn't because the
browser->top didn't got revalidated after the timer ran and the
underlying data structure got updated.

perf hists browser: Update the browser.nr_entries after the timer
...
Previously the hist_browser dealt with a static tree of entries, now it
needs to update the nr_entries in the browser after the timer runs.
A better solution will come when moving using another thread for the
collapse_resort, etc, but for now this is ok.

perf hists browser: Fix TAB/UNTAB use with multiple events
...
When requesting multiple events, say:
# perf top -e instructions -e cycles -e cache-misses
The first screen lets the user chose what to see first, then to switch
one can either use the left key to get back to the event menu or simply
use TAB to go the next and shift+TAB to go the prev.
When using TAB/UNTAB the call to perf_evlist__set_selected(event) was
missing, fix it.

I.e. when in the annotate TUI window, if Enter is pressed over an

This is just a proof of concept and works only on x86_64, more work is
needed to support kernel modules, userland, other arches, etc, but
should already be useful as-is.

perf top: Reuse the 'report' hist_entry/hists classes
...
This actually fixes several problems we had in the old 'perf top':
1. Unresolved symbols not show, limitation that came from the old
"KernelTop" codebase, to solve it we would need to do changes
that would make sym_entry have most of the hist_entry fields.
2. It was using the number of samples, not the sum of sample->period.
And brings the --sort code that allows us to have all the views in
'perf report', for instance:
[root@emilia ~]# perf top --sort dso
PerfTop: 5903 irqs/sec kernel:77.5% exact: 0.0% [1000Hz cycles], (all, 8 CPUs)

^C
All the filter lists can be used as well: --dsos, --comms, --symbols,
etc.
The 'perf report' TUI is also reused, being possible to apply all the
zoom operations, do annotation, etc.
This change will allow multiple simplifications in the symbol system as
well, that will be detailed in upcoming changesets.

perf hists browser: Fix seg fault when annotate null symbol
...
In hists browser, press hotkey 'a' to annotate current symbol.
Now it causes segment fault if 'a' is pressed on a null symbol.
Here are 2 small bugs:
- In perf_evsel__hists_browse, the condition check after 'a' is pressed
is not correct, we should check ->sym instead of ->map.
- In symbol__tui_annotate we must check whether sym is NULL or not
before getting annotation structure.
This patch fixes above 2 small bugs.

perf tools: Improve support for sessions with multiple events
...
By creating an perf_evlist out of the attributes in the perf.data file
header, so that we can use evlists and evsels when reading recorded
sessions in addition to when we record sessions.
More work is needed to allow tools to allow the user to select which
events are wanted when browsing sessions, be it just one or a subset of
them, aggregated or showed at the same time but with different
indications on the UI to allow seeing workloads thru different views at
the same time.
But the overall goal/trend is to more uniformly use evsels and evlists.
