Description

Commit d489e7557 modified Charon to accept multiple certificates from the other party in IKEv1 messages but the modification was restricted to the main mode and the aggressive mode remained restricted to one certificate in a message. The restriction prevented strongSwan from connecting to a certain instance of Fortinet IPsec VPN that required the aggressive mode and was sending the whole certificate chain in R1. I have removed remaining restrictions in `src/libcharon/encoding/message.c` (see the attached patch--it was made for 5.4.0 but I am sure 5.5.0 is affected as well) and it works now.
