  ovpn: use bound address in UDP when available (2025-11-11 22:18:13 +0100)

----------------------------------------------------------------
This batch includes the following features:
* use proper len constant when declaring array in CMD_KEY_SWAP parser
* use bitops API rather than manual operations in pktid.c
* send peer float event notification (netlink)
* exclude link-local v6 addresses from RPF check
* add support for asymmetric peer IDs (TX vs RX ID)
* improve memory allocations layout in encrypt/decrypt
* honour socket bound device and source address in routing lookup
