The previous version causes an unsigned integer underflow. That
is not wrong, but still change it.
Also use g_array_remove_index_fast() because the list of routes
is unsorted anyway.
build_rtnl_addr() has two parameters "lifetime" and "preferred". Both
count from *now*.
Fix nmp_object_to_nl() to properly set these timestamps. This bug had
not real consequences, because the only place where we use
nmp_object_to_nl() the arguments are 0.
When ping is launched to check the connectivity to the gateway it may
return earlier than the given timeout in case of error. When this
happens we need to respawn it until the timeout is reached.
While at it, increase maximum timeout value to 600 seconds.

When the platform link gets removed outside of NetworkManager, we would
unmanage the device first. By checking the device state reason
NM_DEVICE_STATE_REASON_REMOVED, we would then not deconfigure the
interface, as it is already gone.
This was not correct because we must at least stop the dhcp client.
Otherwise the dhclient process keeps running. That meant, if the device
reappeared later, we would start dhclient again. Then we would find the
PID of the still running instance in the pidfile and kill it only than.
Fix it by replacing the 'deconfigure' boolean by a tri-state
'cleanup_type'.
We kill the process based on the PID from the pidfile. This can be
our own child process so we must use nm_utils_kill_child_sync()
instead of nm_utils_kill_process_sync().
kill(pid,sig) can return success for zombie processes. This
caused nm_utils_kill_process_sync() to hang indefinitely.
Fix it by also checking the process state.
ip[46]_config_merge_and_apply() do assume the settings that are merged later in
override the previously set ones and not the other way around. Otherwise e.g. a
gateway address from DHCP could override what's set in the connection.
Add a macro to insert the necessary compiler/linker magic to add a
copy of an existing symbol to an older version. Also, update
check-exports.sh to be able to check for such symbols by listed them
commented-out in the appropriate section.

Also rewrite resolv.conf if the configuration didn't actually change.
Especially, react on SIGUSR1 which does not reload the configuration but
only writes "resolv.conf".
https://bugzilla.redhat.com/show_bug.cgi?id=1062301
Also react on SIGUSR1 and SIGUSR2, beside SIGHUP.
Only for SIGHUP actually reload the configuration from
disc. For the other signals only emit a config-changed
signal.
Since commit ab6548c62134 ("device: better accept external IP
changes"), ipX_config_merge_and_apply() applies the configuration
static settings to an intermediate, initially empty configuration
(priv->con_ipX_config) instead of the composite configuration, and
thus the handling of ignore-auto-routes and ignore-auto-dns options
done in nm_ipX_config_merge_setting() has no effect.
Fix this by clearing the routes and the DNS information when needed
before merging static settings to the composite configuration.

Example:
$ nmcli con add type eth con-name profile ifname nosuch
$ nmcli con up profile
or
# ip link set eth0 down
$ nmcli con add type eth con-name my-eth0 ifname eth0
$ nmcli con up my-eth0

Without that we can remove addresses from con-ip6-config due to external
changes *before* it is applied and thus manual IPv6 addresses are not applied
together with ipv6.method=auto.
Testcase:
$ nmcli con add type ether con-name AAA ifname eth0 autoconnect no
$ nmcli con mod AAA ipv4.addresses 1.1.1.1/24 ipv6.addresses 99::99/64
$ nmcli con up AAA
