perf ui tui progress: Implement the ui_progress_ops->finish() method
So that we can erase the progress bar after we're done with it, avoiding things like: ------------------------------------------------------------------- ┌─Error:──────────────────────────────────────────────────────┐ │Can't annotate unmapped_area_topdown: │ │ │ │No vmlinux file with build id a826726b5ddacfab1f0bade868f1a79│ │was found in the path. │ │ │ │Note that annotation using /proc/kcore requires CAP_SYS_RAWIO│ ┌Processin│ │──┐ │ │Please use: │ │ └─────────│ │──┘ │ perf buildid-cache -vu vmlinux │ │ │ │or: │ │ │ │ --vmlinux vmlinux │ │ │ │ │ │Press any key... │ └─────────────────────────────────────────────────────────────┘ Can't annotate unmapped_area_topdown: ------------------------------------------------------------------- I.e. that finished progress bar behind the error window. It is not a problem when we end up redrawing the whole screen, but its ugly when we present such error windows, provide a TUI method so that code like the above may avoid this situation, as will be done with the annotation code in the next cset.
