FRED support as defined starting from the SDM rev. 90, requires a new
'events' entry point to receive user and kernel mode exceptions and
interrupts notifications from the hardware. A minimal asm trampoline is
enough, rest can be implemented in C due to the clean FRED organization
of the event reporting.
The syscall entry is handled by a microptimized assembly path, directly
calling into the amd64_syscall() handler, instead of the generic events
entry point.

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.
