8d89b16ea4 net: lwip: Use ipaddr helpers
The ip_addr_t of lwIP has support for both IPv6 and IPv4 addresses.
Some lwIP commans is directly accessing the internal addr field of the
ip_addr_t instead of using ipaddr helper functions.

Change to use ipaddr helper functions where appropriate to remove direct
access of the internal addr field. Also change a few instances from ip4
to the version less ipaddr helpers.

There is no intended functional change, besides the change from using
ip4 addr helper to using version less ipaddr helper.

a8a81af848 cmd: lwip/wget: avoid NULL dereference in _set_cacert()
Running `wget cacert builtin` leads to a crash in _set_cacert():

    Unhandled exception: Load access fault

Function _set_cacert() dereferences variable wget_info.
We must initialize it before executing the cacert sub-command.

90c05f68fc net: lwip: ping: set net_try_count to 1
The legacy network stack sets net_try_count to 1 at the beginning of the
net_loop() function. This is required for net_start_again() to work
properly. Therefore, set the variable accordingly in the do_ping()
function when NET_LWIP=y. This fixes an issue where a ping to an
unreachable destination would run twice on the same network device. For
example with qemu_arm64_lwip_defconfig:

 => dhcp
 DHCP client bound to address 10.0.2.15 (3 ms)
 => ping 10.0.0.1
 Using virtio-net#32 device
 ping failed; host 10.0.0.1 is not alive
 Using virtio-net#32 device
 ping failed; host 10.0.0.1 is not alive
 => QEMU: Terminated

8f80e30579 lwip: sntp: remove redundant sys_check_timeouts()
Now that sys_check_timeouts() is called in net_lwip_rx(), there is no
need to call it from the SNTP receive loop. Remove the redundant call.

1361d9f4f0 lwip: dns: do not print IP address when a variable is specified
When calling "dns <hostname> <varname>", do not print out the IP address
of <hostname> onto the console. Print it only when no variable is
passed. The reason is to be able to call do_dns() from another command
in need of the DNS services without polluting the output.

the address is in fact never copied into the context. Fix that.
