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

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

[Namhyung Kim]

From: Namhyung Kim <namhyung.kim@lge.com>

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.

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

[Namhyung Kim]

From: Namhyung Kim <namhyung.kim@lge.com>

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.

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

[Namhyung Kim]

From: Namhyung Kim <namhyung.kim@lge.com>

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.

When is the progress bar shown? Why does it need to be a separate dialog? 
Can't we embed it in the current perf window (and make the other 
UI components disabled if necessary)?

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

perf ui tui: Move progress.c under ui/tui directory

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.

perf ui gtk: Implement ui_progress functions

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.

perf ui: Add ui_progress__finish()

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.
