When the icon-release signal is emitted on a GtkSearchEntry, the
contents is now cleared only if it's for the secondary icon. The primary
icon can be used for another purpose.

Bug 704216: Fix prototype for gdk_quartz_device_core_warp.
Make info bar action area horizontal

A vertical action area causes the info bar to be imposingly large.
This defeats the whole point of the info bar which is to be
unobtrusive. Not to mention it is impossible to make it look
and feel good.
Make the info bar action area border the same as the internal spacing

Using a consistent spacing feels much more polished.
Fix infobar docs to not mention type colors

The theme may not use colors to distinguish the info bar
message types.
