Add UCI section general which holds the uci parameter network defining on
which interface(s) the snmp agent is reachable for inbound snmp requests
in case the firewall zone does not allow INPUT traffic by default.
For the different zones to which the different interfaces belong firewall
procd input rules are created making the snmp agent reachable on udp port
161.

According to the snmpd.conf man page, the engineID of an snmp agent
should be consistent through time. However, it seems that the engineID
changes every reboot. Add options to configure how the engineID is
generated. The default setting generates it based on the MAC address of
the eth0 interface.

We believe snmpd-static isn't useful, but download stats show it's still
being downloaded. Instead of dropping it, make it a dummy package that
depends on snmpd.

Instead of causing nondeterministing conditional compilation depending on
whether libnl-core happens to be present or not, fixup the net-snmp package
to link against libnl-tiny which is present by default on the majority of
systems.
In order to successfully build against libnl-tiny, a number of things had
to be fixed in both the upstream configure and the outer Makefile:
- Add a patch which fixes the upstream configure macros to properly handle
cases where the cache variables for nl_connect() and netlink.h tests are
predefined. Without this patch, all subsequent link tests in configure
will fail, causing the build system to assume functions like opendir() or
readdir() to be missing, leading to build failures later on due to
conflicting redefinitions of structures and function prototypes
- In the same patch, stop probing the host systems /usr/include/libnl-3 if
ac_cv_header_netlink_netlink_h is given. This brings the proprietary
configure bits in line with the behaviour expected from autoconfig in a
cross compile setting
- Explicitely request nl support by passing the --with-nl flag to configure
- Pass the required cache variables to skip the broken tests for
nl_connect() and netlink.h
- Amend TARGET_CPPFLAGS to let net-snmp's build system discover nl-tiny's
netlink/netlink.h and netlink/socket.h
- Enable the autoreconf fixup to regenerate the broken shipped configure
from patched macros
- Adjust the depends to unconditionally require libnl-tiny

When libnl-core is enabled, but libnl isn't, build fails because of a
missing dependency on libnl-3.so.200. Depending on libnl-core seems to
work for both cases.

Update to 5.7.3 by refreshing patches; remove 800-format-security
as upstream integrated.
Add libnl dependency in the package Makefile as net-snmp will check
if libnl is enabled in config_os_libs2.
Remove unneeded PKG_FIXUP build variable.

When applying wireless configuration changes, the ifindex of the
wireless interface(s) change. While snmpd picks up the new interfaces
with the correct index, it does not remove the old ones:
IF-MIB::ifName.23 = STRING: wlan0
IF-MIB::ifName.24 = STRING: wlan1
IF-MIB::ifName.25 = STRING: wlan0
IF-MIB::ifName.26 = STRING: wlan1
This causes problems for monitoring tools that use ifName (or ifDesc) as
interface reference. Add a trigger that reloads snmpd on interface
up/down events so that it will no longer have the old interfaces.

When an ifindex for an interface changes, some monitoring tools can no
longer find the interface and send alerts. Monitor all network
interfaces via the procd netdev parameter, so that
/etc/init.d/snmpd reload will restart snmpd if any ifindex changed.
