Subject: [PATCH] siphash: add SPDX tags as sole licensing authority
Date:   Wed, 18 May 2022 15:23:45 +0200

The text "dual BSD/GPLv2 license" is somewhat ambiguous, and moving this
over to SPDX is overdue. This commit adds SPDX tags to the relevant
files and clarifies that it's GPLv2 only and 3-clause BSD. It also
removes the old text, so that the SPDX tags are the only source of the
information.
