Hi,
we recently had the need to expose interface counter of
network namespaced interfaces on Linux.
So this patch adds partial support for this by wrapping
relevant code in setns() pairs.
Feedback is welcome!

+This text comments on the partial support for network namespaces in net-snmp.
+
+Background:
+ When you move one of your Linux network interfaces into a network namespace,
+ net-snmp will no longer be able to collect data on that interface.
+ This modification starts to add some network-namespace awareness to the
+ if-mib part of net-snmp.
+ The new behaviour is disabled by default. You can enable it by setting
+ environment variable $SNMP_NETNS to "1".
+
+Approach:
+ * enumerate namespaces by accessing /var/run/netns/
+ * wrapping the appropriate netlink and ioctl action into a pair of setns() calls
+ * prefixing exposed interface names with the name of the netns and a "/"
+ * limit interface indices to SNMP_IFINDEX_BITS bits and use the remainder to
+ store the netns index; this is done to achieve uniqueness for interface indices
+ (namespace names are lexicographically sorted to get some persistence)
+
+Example Output:
+ .1.3.6.1.2.1.2.2.1.2.1 = STRING: lo
+ .1.3.6.1.2.1.2.2.1.2.2 = STRING: em1
+ .1.3.6.1.2.1.2.2.1.2.3 = STRING: docker0
+ .1.3.6.1.2.1.2.2.1.2.5 = STRING: tap0
+ .1.3.6.1.2.1.2.2.1.2.1025 = STRING: test3/lo
+ .1.3.6.1.2.1.2.2.1.2.1028 = STRING: test3/tap0
+ .1.3.6.1.2.1.2.2.1.2.2049 = STRING: test2/lo
+ .1.3.6.1.2.1.2.2.1.2.2052 = STRING: test2/tap0
+
+ (In this example there are 2 non-global namespaces "test2" and "test3".)
