zebra: increase maximum label stack depth
* Bump MPLS_MAX_LABELS from 2 to 16;
* Adjust the static_nh_label structure and the mpls_label2str() function;
* On OpenBSD, print an error message when trying to push more than one
label at once (kernel limitation). While here, add support for MPLSv6
FTNs in OpenBSD.
This is not the full package. We still can't pop multiple labels at once,
or do things like swap a label and push other ones. We'll address that
in the future.

debian(config)# do sh run

When an external route is received, eigrpd will crash. For now,
quietly discard the TLV. Work must be done to handle tlv

external should not be chooses if an internal exist.

bgpd: bgp process queue optimization
There are several code paths that dump nodes to the queue for route
processing in a loop. This patch tries to reduce memory allocations/freeing
(work item, list node) and thread scheduling overhead by batching the nodes
in a simple queue list.
In the past when route processing wasn't event driven (bgp_scan()), this used
to have a noticeable impact in table loading, convergence time and memory heap
fragmentation due to reduced alloc's/free's.
