processes.  Add end_generation hook for notification when the last
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.

DSOs; most notably, the scoreboard was reinitialized during graceful
restart, such that processes of the previous generation were not
observable.

Other noticeable ones:
* the generation number did not increment properly
* worker's check-config hook didn't detect startup properly,
  so messages about inconsistent directives could have been sent
  to the wrong place

max_daemons_limit wasn't tracked across restart, but as the scoreboard
was always cleared this was a non-issue.

Reinitialization of idle_spawn_rate, hold_off_on_exponential_spawning,
and maxclients-message-reported may or may not have been features,
but the big picture is that the behaviour shouldn't have differed.

These changes should have been part of r758185.

  startup failure in cases where multiple vhosts share the same
  "vhost-id" and private key file.  The cached-key case would
  previously cause an abrupt return from the function, which could
  prevent processing of configured keypairs for other vhosts.  There
  is no apparent reason to check for a "cache hit" against cached keys
  using *any* algorithm types; instead only check against a key with
  the matching type.
