* CHANGE unittest test_copy_data_bytesio() to actually check that the output
data matches the original message string given to io.BytesIO().
* REMOVE class test.test_gnupg.ResultStringIO, as it is now not used
anywhere.
* FIXES test_copy_data_bytesio() not actually testing what it was supposed
to.
* CHANGE unittest test_make_args_drop_protected_options() to discover the
path to the GnuPG binary; the discovered path SHOULD be the same as that
which was discovered upon class instantiation.
* FIXES failure in unittest test_make_args_drop_protected_options() which was
caused by the path to the GnuPG binary being hardcoded.
* ADD patches from Mikael Nordfeldth.
* FIXES#14 issues with strcmp in unittests looking for string literals when
Python3 expects byte strings.
* TODO: perhaps there should be a generalized function in
gnupg/test/test_gnupg.py which automatically translates Python2 strings to
b'' strings.
* CLOSES issue #14.
* ADD docs/change-license-emails.txt, which includes email exchanges between
myself and intrigeri, including links to Debian and LEAP mailing lists with
arguments for and against using AGPL for a library.
* CHANGE license header for all files.
* CHANGE LICENSE file and gnupg/copyright.py to use GPLv3+ text.
GPG signature timestamps are considered UTC, this may cause times to be off
by delta > 1000 in def test_signature_string_verification because it
incorrectly gave gmtime() as an argument to mktime().
Python 2 and 3 docs both say that mktime should have a struct_time argument
"which expresses the time in local time, not UTC". So the test is now using
time.localtime() instead of time.gmtime()
