Add new function `bgp_node_get_prefix()` and modify
the bgp code base to use it.
This is prep work for the struct bgp_dest rework.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
Modify code to use lookup function agg_node_get_prefix()
as the abstraction layer. When we rework bgp_node to
bgp_dest this will allow us to greatly limit the amount
of work needed to do that.

Do a straight conversion of `struct bgp_info` to `struct bgp_path_info`.
This commit will setup the rename of variables as well.
This is being done because `struct bgp_info` is not descriptive
of what this data actually is. It is path information for routes
that we keep to build the actual routes nexthops plus some extra
information.

The work_queue_free function free'd up the wq pointer but
did not set it too NULL. This of course causes situations
where we may use the work_queue after it is freed. Let's

Ignore the return value of some functions in the places we know they
can't fail, and other small fixes.
Regarding the change in bgpd/rfapi/rfapi_rib.c, asserting that
rfapiRaddr2Qprefix() didn't fail is the common idiom inside the rfapi
code.

Convert the list_delete(struct list *) function to use
struct list **. This is to allow the list pointer to be nulled.
I keep running into uses of this list_delete function where we
forget to set the returned pointer to NULL and attempt to use
it and then experience a crash, usually after the developer
has long since left the building.
Let's make the api explicit in it setting the list pointer
to null.
Cynical Prediction: This code will expose a attempt
to use the NULL'ed list pointer in some obscure bit
of code.

Most of the attributes in 'struct attr_extra' allow for
the more interesting cases of using bgp. The extra
overhead of managing it will induce errors as we add
more attributes and the extra memory overhead is
negligible on anything but full bgp feeds.
Additionally this greatly simplifies the code for
the handling of data.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with

header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

Pass pointer to pointer instead of assigning by return value. See
previous commit message.
To ensure that the behavior stays functionally correct, any assignments
with the result of a thread_add* function have been transformed to set
the pointer to null before passing it. These can be removed wherever the
pointer is known to already be null.

The way thread.c is written, a caller who wishes to be able to cancel a
thread or avoid scheduling it twice must keep a reference to the thread.
Typically this is done with a long lived pointer whose value is checked
for null in order to know if the thread is currently scheduled. The
check-and-schedule idiom is so common that several wrapper macros in
thread.h existed solely to provide it.
This patch removes those macros and adds a new parameter to all
thread_add_* functions which is a pointer to the struct thread * to
store the result of a scheduling call. If the value passed is non-null,
the thread will only be scheduled if the value is null. This helps with
consistency.
A Coccinelle spatch has been used to transform code of the form:
if (t == NULL)
t = thread_add_* (...)
to the form
thread_add_* (..., &t)
The THREAD_ON macros have also been transformed to the underlying
thread.c calls.
