Unfortunately, chroot() works only for root user, because of attacks
on setuid binaries (make DIR/lib/ld-linux.so a shell, hardlink to
a setuid binary, chroot to DIR, execute it and get root shell).

When a static interface with explicit gateway and metric in /etc/network/interfaces
is enabled using 'ifup', and further, the BusyBox 'ip' applet is enabled, the
following error message appears at the console (and no default route is added):
ip: either "to" is duplicate, or "prio" is garbage
Tracing ifup reveals that it is attempting to run the following shell command:
ip route add default via <GW> dev <DEVICE> prio <METRIC>
'ip' does not understand the 'prio' argument, causing this error. With 'metric',
it works fine.

While RFC1035 recommends a label not to start with a number, there is
actually no such limitation in dns. One may buy a domain name like
0x1.net and use it.
This commit remove this check and allow a user to use such domains.

Introduce a library routine to package the idiom:
p = xmalloc(b, n);
memcpy(p, b, n);
and use it where possible. The example in traceroute used xzalloc
but it didn't need to.

When 'if -a' runs into an failure on an interface all further
interfaces won't be correctly updated in ifstate. This patch
inserts a new variable that only tracks the current interfaces
failure so that the write to ifstate can rely on this and not
the one for the functions return value.
