tests: ignore stderr for expect
expect redirects both stdout and stderr to its input. This causes
serious problems when libzebra prints log messages to stderr, which are
then asynchronously inserted in the middle of lines of stdout test
output. Ultimately this makes testbgpmpattr fail on FreeBSD.
(The stdio buffering seems to be slightly different on FreeBSD,
triggering the bug.)

lib: Stop potential uninitialized memory access
VRF_UNKNOWN = MAX_INT16_T
The vrf macros to determine where in the bitmap something belongs
assume that the valid values of a vrf are 0 - (MAX_INT16 - 1)

ospf6d: resolve problem with area range lsid creation
The problem reported was that routers downstream from the ABR would have
prefixes in the IPv6 rib that should have been summarized. Testing showed
that the prefixes were absent in the lsdb but not removed from the rib.
The problem (and others) stemmed from determining the link-state id to use
for the area-range statement only from other entries in the range-table. Since
the area range statement creates inter-prefix LSAs (summaries) which are in all
aspects identical to other inter-prefix LSAs, the number space for the lsid
needs to be unique across all inter-prefix LSAs, not just unique between area
range statements. This fix removes the use of range-table specific lsids and
acquires the lsid just as any other inter-prefix LSA.

zebra: fix FIB route updates on *BSD
On *BSD, we update a route in the FIB by removing the old one and then
installing the new version.
With that said, on kernel_route_rib() we need to provide a pointer to
both the old version and the new version of the route.
We were, however, passing a pointer to the new version to both the
'old' and 'new' parameters. This is not a problem on Linux, which uses
NLM_F_REPLACE to update routes, but it breaks route updates on *BSD
because the 'old' parameter points to a route that is not installed in
the kernel. The kernel_route_rib() function then fails to uninstall the
supposedly 'old' route and can fail to install the new version as well if
the kernel doesn't support ECMP (e.g. FreeBSD with default configuration).

Since commit a78d75b0, this is not necessary anymore because
ospf_sock_init() now sets the OSPF send buffer size to a very high value
(8MB). Also, the previous logic was broken because it didn't account
