Just convert all uses of thread_cancel to THREAD_OFF. Additionally
use THREAD_ARG instead of t->arg to get the arguement. Individual
files should never be accessing thread private data like this.

Change thread_cancel to take a ** to an event, NULL-check
before dereferencing, and NULL the caller's pointer. Update
many callers to use the new signature.

Create appropriate accessor functions for the rn->lock
data. We should be accessing this data through accessor
functions since it is private data to the data structure.

Remove mid-string line breaks, cf. workflow doc:
.. [#tool_style_conflicts] For example, lines over 80 characters are allowed
for text strings to make it possible to search the code for them: please
see `Linux kernel style (breaking long lines and strings)
<https://www.kernel.org/doc/html/v4.10/process/coding-style.html#breaking-long-lines-and-strings>`_

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.

SA has found a case where we did a table lookup of a rn( and
associated lock of that node ) where we did not unlock it.
Unlock the node before moving on to the next one.

We make the assumption that ->attr is not NULL throughout

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
modify the work_queue to set the pointer for you.

The prefix_rd2str uses a buffer size of RD_ADDRSTRLEN.
Modify the code to consistently use this for all of BGP.

PREFIX_STRLEN is the correct length for buffers needed to output
a prefix2str. Additionally cleanup some setting of the last

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
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.
