parentperf ui browser: Introduce ui_browser__input_window (diff)
perf ui browser: Add 's' key to filter by symbol name
Now user can enter symbol name interested via ui_browser__input_window, and perf can process it using hists__filter_by_symbol(). Giving empty symbol (by pressing 's' followed by ENTER) will disable the filtering.
