This removes the need to sleep for 3 seconds after setting up the
interfaces, but does mean we lose detection of address clashes on
the inteface - it's a trade off

In testing here, this was necessary to prevent daemons reporting 'Cannot
assign requested address' for IPv6 addresses when they attempt to bind()
to the interface address. This only seems to affect v6 addresses - v4
addresses seem to be immediately available to bind() - but a 3 second
pause shouldn't hurt given that the other methods of configuration can
block for up to 15 seconds.

* Rename rc.inet1.conf options
USE_STATELESS6 -> USE_AUTOCONF6
NETMASK6 -> PREFIX6
* Shell syntax and comment fixes
* Removed some redundant code
* Sleep after loading the network card module to allow it to register
* Added error checking when adding IPs to an interface
* Modify if_down() to bring all types of interface down
* Only do MTU and PROMISC set up if the interface comes up
* No longer skip alias config if using USE_AUTOCONF.

DHCP may have set the MTU to what the DHCP server advertises,
but our override should take precedence.

TODO: I (RW) am not convinced that this will behave correctly if the
ipv6 address is static while ipv4 is dynamic, or vice versa.

Conditional expression like [ test1 -a test2 ] should be avoided as it
is not well defined.

Instead of "ip | sed", just read the sysfs file in which hardware

There's no need to $(cat .../uevent | grep DEVTYPE) and then compare it
to what we're looking for. grep can do all of it for us ("Useless Use of
Cat").
While at it, if we have three ways of checking whether a device is
wireless, let's order them from least expensive (checking dir is only
one stat()) to most expensive (iwconfig | grep). Proof of correctness:
if "iwconfig | grep" is returning true and the other two methods are
not, we will still reach "iwconfig | grep" in the series of if/elif.

There is a slight problem with things like
grep lo: /proc/net/dev
especially with tun/tap devices with can have arbitrary names.
Consider a scenario where you name your tap iface "trololo":
$ grep -c lo: /proc/net/dev
2
$
To fix this (quite hypothetical, but still) problem, instead
of simple grepping in /proc/net/dev, check of sysfs path
existence (/sys/class/net/<interface>).
Same fix in if_up() and if_down() for non-loopback interfaces.
While there, also strip colon-whatever from interface name
(what I think was the original idea behind a construct like
grep $(echo ${1}: | cut -f 1 -d :): /proc/net/dev) by using
parameter expansion: ${1%%:*} will remove the longest suffix
matching ":*", ie. colon-and-everything-after.
This is supported by POSIX:
http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html
Alternative solution would be to change the grep pattern to
grep '^ *lo:' /proc/net/dev
