firewall: optimize DNAT rules and skip invalid rules and redirects (#14485)

	- instead of writing one (or more) ACCEPT rules in the filter table
	  for each redirect install a global ctstate DNAT accept rule per zone

	- discard rules and redirects which have invalid options set instead
	  of silently skipping the invalid values

uClibc: Deactivate oversized thread stack cache

A small system like the common home router doesn't have 40 MiB per process for
a dirty stack cache. This can easily lead to an overbooking OOM problem and
caused a lot of hangs+reboots on 32 MiB systems running nodogsplash.

Not using a stack cache can increase the time to spawn new threads. This is
hopefully no problem for system not running a lot of parallel computations.
