Introduce jail_ifname option to define the name of a Linux network
interface when moved into a jail's network namespace.
This is useful for containers which expect the network interface to
have a specific name (eg. 'host0' in case of systemd).
While at it, clean-up and fix bugs in jail interface up/down routines.

Prepare netifd for handling procd service jails having their own
network namespace.
Intefaces having the jail attribute will only be brought inside the
jail's network namespace by procd calling the newly introduced ubus
method 'netns_updown'.
Currently proto 'static' is supported and configuration changes are
not yet being handled (ie. you'll have to restart the jailed service
for changes to take effect).
Example /etc/config/network snippet:
config device 'veth0'
option type 'veth'
option name 'vhost0'
option peer_name 'virt0'
config interface 'virt'
option type 'bridge'
list ifname 'vhost0'
option proto 'static'
option ipaddr '10.0.0.1'
option netmask '255.255.255.0'
config interface 'virt0'
option ifname 'virt0'
option proto 'static'
option ipaddr '10.0.0.2'
option netmask '255.255.255.0'
option gateway '10.0.0.1'
option dns '10.0.0.1'
option jail 'transmission'

The neighbor or neighbor6 network section makes neighbours
configurable via UCI or proto shell handlers. It allows to
install neighbor proxy entries or static neighbor entries
The neighbor or neighbor6 section has the following types:
interface : declares the logical OpenWrt interface
ipaddr : the ip address of the neighbor
mac : the mac address of the neighbor
proxy : specifies whether the neighbor ia a proxy
entry (can be 1 or 0)
router : specifies whether the neighbor is a router
(can be 1 or 0)

cppcheck found printf functions with signed instead of unsigned
formats. Fix those as well as some non-matching function
declarations.

The veth config code mostly handles the primary interface of a veth pair,
the secondary interface is not explicitly referenced and will be found as
an unrelated interface after the pair has been created.
This doesn't only allow us to keep the veth code simple (and similar to
existing device handlers), but will also avoid complicating handling
unnecessarily in case the secondary interface is moved into another network
namespace.

Route proto support is usefull when using route distribution
via a routing daemon.
The route proto parameter can be specified via the route proto
uci config parameter, it can hold a numerical value or the string
values unspec, kernel, boot, static or a string present in
/etc/iproute2/rt_protos.

Reverse path filtering config support; possible values are:
0: no source validation
1|strict: strict mode as packet will be dropped if the
incoming interface is not the best reverse path
2|loose: loose mode as packet will be dropped if the
source address is not reachable via any interface

When a device with the same name is deleted and created again in the kernel
the ifindex changes.
A race condition will occur when netlink event messages linked to the old device
are processed and will thus overwrite the correct ifindex of the new device.
Further make sure a valid ifindex is in place for both external and internal
devices when setting the state to enabled.

Do not treat RT_TABLE_MAIN as RT_TABLE_UNSPEC in system_resolve_rt_table() in
order to allow ip rules with lookup main to work as expected.
Provide a new function system_is_default_rt_table() to allow calling code to
specifically test for RT_TABLE_MAIN, this is going to be needed for the
backwards compatible handling of the table attribute in route objects.

Patch adds route type support in netifd by means of the route parameter type.
By default the route type was unicast; the parameter adss support for local/broadcast/multicast/unicast routes which will be put into the appropriate routing table.
If route type parameter is unset the route type will be unicast as before.

At moment netifd supports just 802.1q vlan, you can configure them using a concise but "hacky"
syntax using an interface config section, with this patch netifd acquire the capability
of configuring 802.1ad and 802.1q vlan using config device sections, so you can define a vlan device
plus interface with something like this:
config device 'test'
option type '8021ad'
option name 'test'
option ifname 'eth0'
option vid '1000'
config interface 'testif'
option ifname 'test'
option proto 'none'
option auto '1'
old syntax for 802.1q keeps working so no retrocompatibility problems,
to keep retrocompatibility means also that user must not use name/ifname like eth0.2
for devices declared with the new style because this would trigger the "old style"
when interface config section is parsed
