[PATCH 0/7] perf ui: Add basic error handling for GTK2 front-end (v3)

[Namhyung Kim <namhyung@gmail.com>]

Hi,

This patchset implements ui__warning/error() functions for GTK2.
Patch 1 is a resend (which forgot to cc LKML) and independent of
this series. Patch 2 converts invocations of ui__warning followed
by exit (or similar effect) into ui__error.

I chose GtkInfoBar widget to implement ui__warning since it provides
a simple way to do what we want IMHO. In fact, a guy sat next to me
at the Korean GNOME hackfest suggested to use it. The only problem
is it requires 2.18 (or newer) version of GTK+ libraries. So I added
status bar as a fallback when info bar is not supported, and this
can be used to implement helpline functions later.

Changes from v2:
 * Convert critical use of ui__warning to ui__error (by Ingo)
 * Use GtkInfoBar instead of a message dialog (by Pekka)

Any comments are welcome.

Thanks,
Namhyung
