perf ui/gtk: Add GTK info_bar widget to browser window

The GtkInfoBar is a modern UI component to display messages without
bothering the main window. It'll be used for showing a warning message.

As the GtkInfoBar requires 2.18 (or newer) version of GTK+ library, add
availability check to Makefile too.

perf ui/gtk: Use struct perf_error_ops

Define and use perf_gtk_eops to provide a GTK2 message dialog for error
reporting and a info_bar for warning.

As GtkInfoBar requires recent GTK+ libraries, provides a fallback
implementation using statusbar widget too.
