Otherwise, when BalancerPersist is enabled, we might fail (re)starting with a
saved slotmem if a BalancerMember was renamed (e.g. PR 62308's port change).
This is because the renamed member is considered a new one, while the old name
still reserves a slot, so we end up missing one room. The overall number of
members does not change so the sizes check succeeds thus the persisted slotmem
is not invalidated. Yet the slomem is not really compatible.

By clearing inuse flags, we still allow for slots to be reused if their index
did not change (thanks to ap_proxy_find_balancershm() and slotmem_fgrab() at
the given index), but will also invalidate renamed slots which don't match the
index. We now have the correct behaviour by slot and the server (re)starts in
any case.

Since persistent files are also reused on stop/start, we must ensure that
they match the same descriptor when reused on the next startup, so add it
to integrity metadata.

Also, the descriptor being the first field in the SHM, we don't need to
copy on the stack it in several places, and can handle it as a pointer.

Don't try to attach SHMs on startup, they might be from a previous crash and
prevent the server to start (on failure to reuse it).

On mpm_winnt though, the pre/post_config() phases are re-run in child process,
and the parent process already created the SMs, so they must be attached there.

r1831394 is the right follow to r1830800 to preserve "inherited" slotmems in
children processes.

While at it, comment on the expectations from mod_proxy_balancer w.r.t.
slotmem_attach() implementations, and eventually how we could improve the API
later (w/o backporting to 2.4.x).

The caller might (and actually balancer_child_init() does) rely on
slotmem_attach() to not mangle the passed in/out slotmem pointer on
failure.

Don't call slotmem_attach() if the slot is already initialized/reused, that
used to work previously because the returned error status is ignored, but
r1830800 changed the function to forcibly reset the returned slot pointer to
NULL first.

There is no point to call slotmem_attach() in this case, the slot is already
initialized because it's either inherited/fork()ed on Unixes, or on Windows
the attachment happened in post_config/slotmem_create() already.

One case where slotmem_attach() would fail is when balancers are defined
globally (main server) and some virtualhosts don't have/use any mod_proxy
configuration/directive. In this case their proxy server config is a pointer
copy of the main server thus their slots are already initialized in both
post_config and child_init hooks. While the case was already handled in
the balancer_post_config(), it did not in balancer_child_init() where we
relied on slotmem_attach() to be a noop.
