* common/argparse.c, common/argparse.h: Change license -- On 2011-09-30 the license of these two files were changed from LGPLv2.1 to LGPLv3+/GPLv2+. This was part of a general change from files with either GPLv3+ or LGPv2.1+ to this combination so to allow the use of these files with GPLv2only code. Since then the code was only modified by employees of g10 Code GmbH under my direction and myself. The following changes commit 7249ab0f95d1f6cb8ee61eefedc79801bb56398f Author: Daniel Kahn Gillmor <dkg@fifthhorseman.net> AuthorDate: Tue Jan 10 15:59:36 2017 -0500 commit eed16ccebf8fd1fdf9709affbd5c831f6957b8ae Author: Daniel Kahn Gillmor <dkg@fifthhorseman.net> AuthorDate: Fri Nov 21 17:04:42 2014 -0500 and a few typo fixes are minor and thus not copyright-able.
