With underlying dynamic data structures we need to invalidate pointers
to them after a timer, as that entry may have vanished (decayed in top,
for instance).
I forgot about browser_ui->top. Fix it by resetting it to null after a
timer. The seek operation from SEEK_SET will then set it to a valid
entry because it starts from rb_first(&hists->entries).

When using multiple events the 'top' and 'report' tools will first
present the user with a menu to choose the event to browse.
After that the user can either press <- to go back to the menu and
choose another event or instead press TAB to go the next event without
having to go back to the menu or shift-TAB (UNTAB) to go the previous
event, useful to quickly visually see if multiple events are correlated.
The handling of each hists browser return was broken by the ed7e566,
that combined both switches, the first that was for choosing the event
and the second that was for checking if switching to the next event
without passing thru the events menu.
Repeat with me: Don't be clever like that.
Fix it by moving the switch to right after the call to the hists
browser, making abundantly clear that the two switches are unrelated.
This also fixes a compiler warning about the 'pos' variable being
possibly used unitialized.

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.

is not correct, we should check ->sym instead of ->map.
- In symbol__tui_annotate we must check whether sym is NULL or not

When looking at a callchains enabled perf data file one can find it
tiresome to start with all callchains collapsed and then to have to go
one by one expanding them.
So associate 'E' with "Expand all callchains" and 'C' with "Collapse all
callchains".
This way now one can have the top level view and then switch to/from
having all callchains expanded.
More work is needed to allow expanding just from one branch down to its
