In the map of active workers, don't print spaces for scoreboard
slots which aren't used due to ThreadsPerChild < ThreadLimit or 
MaxClients/ThreadsPerChild < ServerLimit; simply omit those slots
from the display.  Workers in those slots which are gracefully
exiting (from a previous generation with a different MPM config)
will be displayed, and the map will shrink as those workers exit.

trunk mod_status relies on this value for proper formatting
of the workers; now we see '-' for the idle WinNT MPM workers
instead of ' '

MPM child of a generation exits.

end_generation is implemented completely by core using the
child_status hook run by the MPM.

simple and mpmt_os2 MPMs don't currently run the child_status
hook, so neither hook is invoked with those MPMs.

the extra info is helpful when using a generic listener on an IPv6-
enabled box when either IPV6_V6ONLY isn't defined for the APR build
or httpd is built with IPv4-mapped addresses enabled 

in that case you'll see the parent writing one socket but the child
expecting too, before it bails out with

the MPM's equivalent of "reached MaxClients" is now ERR instead of
WARNING

the message when the MPM child exits due to excessive errors is
raised from ERR to CRIT

the caller of mpm_get_completion_context() could log random error
values (GetLastError() or rv), so solve as follows:

. mpm_get_completion_context() always logs its errors
. caller only logs when it is taking a rare action on such errors, and
  doesn't pretend to know the error code of the last such error
