Clarify licenses

- add license headers to everything
- convert a few files from public domain or LGPL2.1+ to GPL2+
- some archaeology to clarify which files are from which library
parent 517288ae

Too many changes to show.

To preserve performance only 1000 of 1000+ files are displayed.

Inkscape license
================
Most of Inkscape source code is available under the GNU General Public License,
version 2 or later, with the exception of a few files copied from GIMP, which
are available under GNU GPL version 3 or later. As such, the complete binaries
of Inkscape are currently covered by the terms of GNU GPL version 3 or later.
Most Inkscape source code is available under the GNU General Public License, version 2 or later.
Several standalone libraries contained in Inkscape's source code repository are
available under GNU Lesser General Public License or the Mozilla Public License.
Notable exceptions are:
- some libraries in src/3rdparty and src/2geom (mostly GNU Lesser General Public License or Mozilla Public License).
- a few files copied from GIMP, which are available under GNU (L)GPL version 3 or later.
- a few files which are dual-licensed, which means that they offer the additional permission to alternatively use them under another license.
As such, the complete binaries of Inkscape are currently covered by the terms of GNU GPL version 3 or later.
License of individual source files
==================================
The license of each individual inkscape source file can be found in the first few lines after "SPDX-License-Identifier:". The license text of every such license can be found in LICENSES/. Some files are dual-licensed, e.g. "GPL-2.0-or-later OR MPL-1.1", which means you can choose one of these licenses.
Libraries have their COPYING or LICENSE file in the respective subdirectory.
See also https://spdx.org/licenses/ for the full license texts, and https://spdx.org/ids for the standardized header format.
License Compatibility
=====================
Suggested reading for license version compatibility: https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility
Roughly summarized (I am not a lawyer, this is not legal advice):
- You may legally make the following license changes without having to ask anyone:
LGPL-2.1-or-later -> GPL-2.0-or-later -> GPL-3.0-or-later
LGPL-3.0-or-later -> GPL-3.0-or-later
- Due to that, the resulting inkscape must be under GPL-3.0-or-later.
- Any license that is not "-or-later" is evil and must not be used in the inkscape project.
See the files GPL2.txt and GPL3.txt for the full license text.

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
