OpenBSD 7.2

Significant effort into ddb(4)

Various kernel improvements:

Allowed bsd.rd and bsd/bsd.mp to boot on Oracle Cloud amd64 instances.
Added support for switching from glass console to serial console on arm64 systems that default to glass console.
pf(4) automatically allows IGMP and ICMP6 MLD packets with the router alert option. Special allow-opts rules are no longer needed for multicast discovery.
Fixed a pf(4) NULL dereference panic triggered by relayd(8).
Implement "show all routes" to print routing tables in ddb(4).
Added a method (ESC D) to enter ddb(4) on serial drivers that do not have a true BREAK mechanism.
Added "show all routes" and the ability to show individual routes (e.g. "show route 0xfffffd807e9b0000") to ddb(4).
Added a "show swap" command to ddb(4) to help debugging.
Count dropped network packets due to low memory in netstat(1).
Simplified machine command handling in ddb(4).
