sbin/reboot change, -p behavior default for halt

[Dmitri Nikulin]

Category: misc
Severity: non-critical
Priority: low
Class: update
Release: 5.2-CURRENT

Full description:
Power-off functionality is usually expected from systems which support 
ACPI even half as well as FreeBSD does, yet the default behavior of halt 
is a completely soft shutdown. Environments that use halt (e.g. display 
managers) need messy reconfiguration, and users that aren't aware of the 
-p flag might never learn about it. Using acpiconf properly achieves the 
same result but with even more divergence from what people expect to 
have to type.

Applied from src/sbin, this patch makes -p functionality the default for 
halt (much like on typical GNU/Linux systems).

How to repeat:
halt without -p
