ChangeLog

+1355.	[build]		andreipavelQ
+	--with-dhcp-mysql renamed to --with-mysql and
+	--with-dhcp-pgsql renamed to --with-pgsql. These names were
+	leftovers from old BIND10 times when Kea was part of bigger
+	solution that also provided DNS services. Kea is now a stand-alone
+	software, thus the -dhcp- doesn't make sense in those options any
+	more.
