Modifying the number of proxy balancers or balancer members on restart
could have prevented the server to load, notably on Windows.  PR 62308.

The generation number integrated in the SHM filename allows to create a
new/resized SHM while the previous is still in use by previous generation
gracefully shutting down (Windows prevents SHM/file to be removed in this
case, but even on Unix(es) an unlinked file might not be re-openable while
an inode exists). The generation number is added/incremented only if the
size requirement changed, such that unrelated restarts continue to share
SHMs between generations.

The cleanup handling is also simplified because both the parent process and
the Windows child process need to cleanup everything on exit. This translates
to cleanup_slotmem() being always registered but in the dry load state
(AP_SQ_MS_CREATE_PRE_CONFIG), for both cases still.

If this handler will not handle the request, no need to waste bytes in the request pool.

It allows to read a line directly from an input filter, in blocking mode
or not. Since no request_rec is needed, a pool may be given.

Existing ap_[r]getline() function are now based off ap_fgetline() by calling:
    ap_fgetline(s, n, read, r->proto_input_filters, flags, bb, r->pool);

Will follow up with a new ap_get_mime_headers_*() flavor which can be used by
any filter that needs non-blocking and not necessarily has a request_rec (e.g.
ap_http_filter() to read proxied response trailers).

ResponseFieldSize actually applies to headers (not body), so the comment was
valid but did match the code (addressed by r1829642 still).

If f->r->proxyreq is PROXYREQ_PROXY or PROXYREQ_REVERSE in ap_http_filter(),
we are still handling the request, not the response where LimitRequestBody
does not apply.
