In a topology like:
r1(ASBR) ---- 0.0.0.0 ---- r2(ABR) ---- 1.1.1.1 -----r3
where r1 is redistributing statics and area 1.1.1.1 is NSSA, the ABR r2 should
not originate type-4 LSA into the NSSA area. From RFC 3101: "NSSA border routers
should not originate Type-4 summary-LSAs into their NSSAs."
This PR prevents the above LSA of being originated by the ABR r2

During shutdown, when table_manager_disable is called for the default
VRF, its vrf_id is already set to VRF_UNKNOWN, so the expression is true
and the table manager memory is not freed. Change the expression to
compare the VRF name instead of the id. The check in table_manager_enable
is changed for consistency.

Function ospf_te_parse_te() and ospf_te_delete_te() browse TE TLV but also
subTLV. The loop that parse the subTLV check that cummulative read data doesn't
exceed the total size of the TLV. However, the sum variable that counts the
number of read data was wrongly intialize to 0 instead to 4 (i.e. the initial
TLV Header size that is located at the TOP of subTLV).
This patch adjust accordingly the initial value of the counter.

Currently I get bgp_instance_del-test as well as bgp_l3vpn_to_bgp_vrf
failures every ~3-4 runs when under a 40 parallel run with micronet.
Examination of the failure and passing cases always leads to the
failures showing convergence of bgp bestpath immediately after
the show commands to ensure that the routes are there.
Modify the code to look for the fact that the vrf has
converged from routes being passed around across vrf's
and ensure that bestpath has run on them.
