Add OpenSSL additional permissions text to all copyright statements
The OpenSSL license is not completely compatible with the GPLv3+ or LGPLv3+ licenses that our sources are covered under. In order to allow linking against OpenSSL, an additional permission must be granted. GNU Wget already has the required right. We need to append the following text to all the copyright statements (Not just the one containing the OpenSSL source. See Wget repo for examples):
Additional permission under GNU GPL version 3 section 7
If you modify this program, or any covered work, by linking or combining it with the OpenSSL project's OpenSSL library (or a modified version of that library), containing parts covered by the terms of the OpenSSL or SSLeay licenses, the Free Software Foundation grants you additional permission to convey the resulting work. Corresponding Source for a non-source form of such a combination shall include the source code for the parts of OpenSSL used as well as that of the covered work.
