Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC) 
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

* Power Switches:
*
* Power switches are devices on the system that are used by the system
* operator to cause certain types of power management events to happen.
* This may be the closing of a laptop lid, the pressing of a power button,
* or some other type of user-initiated hardware event.
*
* We define the following types of power switches:
*
* Power button This is the "on/off" button on a system,
* or another button which provides a similar
* function. If there is no power management
* daemon present, an event on this button will
* cause a semi-graceful shutdown of the system
* to occur. This kind of button doesn't keep
* state; we only know (care) if an event occurs.
*
* Reset button This is the "reset" button on a system, or
* another button which provides a similar
* function. If there is no power management
* daemon present, an event on this button will
* cause a semi-graceful reboot of the system
* to occur. This kind of button doesn't keep
* state; we only know (care) if an event occurs.
*
* Sleep button This is a button which is dedicated to a
* "sleep" function. This kind of button doesn't
* keep state; we only know (care) if an event
* occurs.
*
* Lid switch This is e.g. the lid of a laptop. This kind
* of switch has state. We know if it is open
* or closed.
