'SANE' is a protocol for remote access to scanners as implemented by the
'saned' daemon. Like FTP, it uses separate control and data connections.
So let´s enable this in the kernel and add them to 'kmod-nf-nathelper-extra'.

NetBIOS name service requests are sent as broadcast messages from an
unprivileged port and responded to with unicast messages to the
same port. This make them hard to firewall properly because connection
tracking doesn't deal with broadcasts.
So let´s enable this in the kernel and add them to 'kmod-nf-nathelper-extra'.

It's related to the upstream kernel commit adf82accc5f5 ("netfilter:

Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
In mainline kernel commit 02c7b25e5f5 ("netfilter: nf_tables: build-in
filter chain type") all chain filters were merged into one file and into
one kernel module to save some memory. The code protected by these
configuration options CONFIG_NF_TABLES_BRIDGE, CONFIG_NF_TABLES_IPV4,
CONFIG_NF_TABLES_ARP, CONFIG_NF_TABLES_IPV6, CONFIG_NF_TABLES_NETDEV and
CONFIG_NF_TABLES_INET was merged into the nft_chain_filter.c file which
is now always compiled into the nf_tables.ko file.
This only happened in kernel 4.19 and OpenWrt has to select these as
modules in older kennel versions. Mark them as build-in in the kernel
4.19 specific kernel configuration file which will then not be
overwritten by the package specific settings which try to make them
modular again.

to bool and the code will not be compiled as a own module any more, but
it will be integrated into nf_nat_ipv4.ko or nf_nat_ipv6.ko to save some
memory.
Activate these options as bool in the generic kernel 4.19 configuration
only, to always build them into the nf_nat_ipv*.ko modules. The kmod
file will still try to select them as module, but the generic
configuration will not be overwritten.
