* Update Scintilla to version 3.7.5
This now requires a C++11-capable compiler.
Closes#1308.
* Test using newer dist on Travis
Since Scintilla needs C++11
* Add debugging code for when configure fails
* Workaround a pkg-config-corsswrapper bug on Ubuntu 14.04

Use a per-line cache to avoid re-computing the offset from the start of
the buffer each time. This dramatically speeds up multiple replacements
on large files.

On GTK2 and GTK3 < 3.3.6 there is no GtkAccessibleClass::widget_unset()
method, so we can't destroy our accessible object right away. So, to
avoid accessing a destroyed widget, we need to check whether the widget
still exists in the the ScintillaGTKAccessible destructor.
In other methods it's not necessary because the wrapping GObject class
makes sure not to forward other when the widget has been destroyed, but
we still have to destroy the C++ instance no matter what, so the check
has to be on this side.
Fixes#1410.
Avoid crash when detaching the widget from the accessible object
without destroying that widget.
In such situations, the widget is still valid but we will have
destroyed the orphaned accessible object. Thus, we must make sure we
disconnected the signal handlers the late accessible had set up on the
widget, as they won't be implicitly disconnected by widget
finalization in this case.
Fixes#1385.
We cannot compute the length in characters after the text has been
deleted, so we need to compute it in BEFOREDELETE. However, we need to
emit the signal once the buffer has actually changed, so we need to
cache the value in-between those events.
