b8af3fbbaf zebra: fix detection of interface renames
Restore the original logic in netlink_link_change() which works like this:
* once an interface event is detected, lookup the associated interface
  by its name;
* call the set_ifindex() function;
* set_ifindex() will lookup the interface again but now by its ifindex. If
  the lookups by name and ifindex yield to different results, then the
  interface was renamed and set_ifindex() will take care of that.

In the future, zns->if_table will be split into two different data
structures to allow faster lookups by both name and ifindex.

Fixes Issue #397.

Regression introduced by commit 12f6fb9.

06b57ec2a4 zebra: fix infinite loop when deleting non-default vrf
How to reproduce the bug:
% ip link add vrf-red type vrf table 10
% ip link set dev vrf-red up
% ip rule add oif vrf-red table 10
% ip rule add iif vrf-red table 10
% ip link add name lo1 type dummy
% ip link set dev lo1 up
% ip link set dev lo1 master vrf-red
% ip link del dev vrf-red
(zebra gets stuck in an infinite loop inside work_queue_run())

The SNMP modules include <net-snmp/net-snmp-config.h>, which won't be

in my tests the files were on the search path even without the flags.

(SNMP_LIBS is not needed because only libfrrsnmp calls into net-snmp
functions.)

fea12efb86 Implement generic label manager
Label Manager allows to share MPLS label space among different
daemons. Each daemon can request a chunk of consecutive labels and
release it if it doesn't need them anymore. Label Manager stores the
daemon protocol and instance to identify the owner client. It uses them
to perform garbage collection, releasing all label chunks from a client
when it gets disconnected or reconnected.

Additionally, every client can request that the chunk is never garbage
collected. In that case client has the responsibility to release
non-used labels.

Zebra can host the label manager itself (if no -l param is provided) or
connect to an external one using zserv/zclient (providing its address
with -l param).

Client code is in lib/zclient.c, but currently only LDP is using it.

TODO: Allow for custom ranges requests, i.e., specify the start label
besides the chunk.
TODO: Release labels from LDP.
