perf report: Support multiple events on the TUI

Browse Source 
The hists__tty_browse_tree function was created with the loop to print
all events, and its equivalent, hists__tui_browse_tree, was created in a
similar fashion, where it is possible to switch among the multiple
events, if present, using TAB to go the next event, and shift+TAB
(UNTAB) to go to the previous.

The report TUI now shows as the window title the name of the event and a
leak was fixed wrt pstacks.
