[gtk/wip/smcv/roaring-license: 49/49] Move roaring bitmaps code to gtk/roaring/ and add a README

[Simon McVittie <smcv src gnome org>]

commit 95cd8c1eb91d34954eacde65832a4bd7002da309
Author: Simon McVittie <smcv debian org>
Date:   Sat Aug 8 16:17:59 2020 +0100

    Move roaring bitmaps code to gtk/roaring/ and add a README
    
    As suggested by Matthias Clasen on gtk!2408. This keeps the
    Apache-licensed stuff together.
    
    As per the discussion on gtk!2408 and gtk!2409, replacing this with
    upstream CRoaring is specifically not supported by the GTK maintainers.

+Roaring bitmaps implementation
+==============================
+
+This directory contains code modified for GTK, based on the Roaring
+bitmaps reference implementation
+[CRoaring](https://github.com/RoaringBitmap/CRoaring).
+
+It is not necessarily compatible with past or future versions of CRoaring,
+and replacing it with a different version or linking to a system copy
+is not supported.
+
+See the source files for copyright and licensing information, and the
+`COPYING` file for the full text of the Apache license, version 2.0.
+
+When proposing modifications for these files, please consider whether they
+are also suitable for submission to CRoaring.
