zebra: Perform safe walk of RIB entries in rib_process()
There is a scenario where a RIB entry is unlinked and freed during RIB
processing. However, the walk of the entries is not being performed in
a safe manner. Fix the code to do this correctly.

lib: Slight Optimization of thread handling.
This commit does these things:
1) Make thread_add_unuse own the setting of THREAD_UNUSED.
2) Move thread->hist finding to to thread_get.
We are storing the thread->hist even when the thread
is on the unused. This means that we check to see
if the funcname or func have changed and we get new
history. Else we've probably just retrieved the last
unused which has the same func/funcanme. This is
a common practice to do THREAD_OFF/THREAD_ON in
quick succession.

zebra: Allow netlink_talk to choose the filter function to call
The netlink_talk call sends a message to the kernel, which
with netlink_talk_filter only waits for the ACK.
It would be nice to have the ability to specify what the handler
function would be for when we send queries about mcast S,G routes
so that we can gather the data returned from the kernel.

lib: Setup prefix.h to allow it to store (s,g)
We need the ability to store the (s,g) in a struct prefix.
This will allow us to consolidate some duplicated code in
pimd as well as set us up to switch from a link list to a
table to store (s,g) state.

build: fix several ldpd XML-CLI build issues
- the location of ldp_vty_cmds.c can be either in srcdir or builddir,
depending on whether a premade file from a dist tarball is used
- perl libxml support is only needed if that file is absent
- the actual perl script wasn't even included in the dist tarball
- the include location doesn't work when srcdir != builddir

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.)
Just ignore stderr for expect.

Introduce internal and IANA defintions for AFI/SAFI and mapping
functions and modify code to use these. This refactoring will
facilitate adding support for other AFI/SAFI whose IANA values
won't be suitable for internal data structure definitions (e.g.,
they are not contiguous).
The commit adds some fixes related to afi/safi testing with 'make check
