13959da95c Reduce the WARNS levels in a couple of places so that we can enable 
-Werror at higher WARNS levels like we did before gcc4 was imported.

06274cee44 - Before doing ioctl(SIOCGIFNETMASK) put the proper IP address into the ifreq, 
to obtain correct netmask in case of interface with multiple aliases.
- While here, remove a comment with a bad idea.

34c96b563e Improve the documentation of "proxyall" knob, somewhat: we do not 
proxy for hosts that are reachable through the same interface the
request came in from.  This feature is mainly for hosts reachable
through some P2P link, e.g. the gif(4) tunnel.

68839124b6 Massive cleanup of the code removing global variables to

Hopefully no functional changes except fixing a couple of
bugs which could cause endless loops if an ioctl() on an

the scope of operation to the ARP entries on a particular
interface.  It should be useful on machines with numerous
network interfaces, e.g., on inter-VLAN routers.

2ab778e1d3 Unbreak this file after the last drive-by committing. We have to 
#include route.h before iso88025.h, and we have to dereference
the trld_route array correctly. (NOTE: I'm not altogether sure
that this is really the correct way to traverse this array. This
just eliminates the build warning/error. It may not work right at
runtime, and I have no way to test it since I lack the necessary
hardware.)
