This patch always enables asynchronous logging which slows
down the system a lot on slow storage and some virtual environments.
It also removes the configuration options in the web
user interface, since this is not configurable any more.

Packets destined for the firewall coming in from the blue
device where accepted too early to be processed by the
firewall input chain rules.

If an IPsec VPN connections is not established, there are
rare cases when packets are supposed to be sent through
that said tunnel and incorrectly handled.
Those packets are sent to the default gateway an entry
for this connection is created in the connection tracking
table (usually only happens to UDP). All following packets
are sent the same route even after the tunnel has been
brought up. That leads to SIP phones not being able to
register among other things.
This patch adds firewall rules that these packets are
rejected. That will sent a notification to the client
that the tunnel is not up and avoid the connection to
be added to the connection tracking table.
Apart from a small performance penalty there should
be no other side-effects.

The hosts file was not regenerated when RED was not connected
which should not be happening.
This patch checks if the file exists. If not, the gateway
line will not be written to /etc/hosts.
With a huge number of access rules, inserting all rules
into the kernel took a long while in which other iptables
tried to access the kernel's ruleset as well, which then
lead to resource conflicts.
Since iptables 1.4.20, the --wait parameter is supported
that will wait for a global xtables lock and then proceed.
This has been messed up a lot because there were multiple
files which indicated that a reload is needed; shell commands
were used to create and remove the indicator file; some
functions were duplicated.
