Subject: [PATCH 1/6] perf ui/tui: Move progress.c under ui/tui directory

From: Namhyung Kim <[email protected]>

Current ui_progress functions are implemented for TUI only. So move
the file under the tui directory. This is needed for providing an UI-
agnostic wrapper.

Subject: [PATCH 3/6] perf ui/gtk: Implement ui_progress functions

From: Namhyung Kim <[email protected]>

Implement progress update function for GTK2 front end.

Note that since it will be called before gtk main loop so that
we should call gtk event loop handler directly.

Subject: [PATCH 4/6] perf ui: Add ui_progress__finish()

From: Namhyung Kim <[email protected]>

Sometimes we need to know when the progress bar should disappear.
Checking curr >= total wasn't enough since there're cases not met that
condition for the last call. So add a new ->finish callback to
identify this explicitly. Currently only GTK frontend needs it.

Subject: [PATCH 2/6] perf ui: Introduce generic ui_progress helper

From: Namhyung Kim <[email protected]>

Make ui_progress functions generic so that UI frontend code will add
its callbacks.

It's called during perf_session__process_events() which is executed
before creating the main window.
