8a00500231 bgpd: add a NULL check to prevent a crash in the rfapi code
The rfapiDeleteRemotePrefixesIt() function checks on several places if
'p' is NULL or not. Introduce an additional NULL check to prevent a
crash from happening.

4b7e606625 bgpd: Convert struct bgp_info to struct bgp_path_info
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.

aadc090505 bgpd: Refactor 'struct attr_extra' into 'struct attr'
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.

56b4067930 *: simplify log message lookup
log.c provides functionality for associating a constant (typically a
protocol constant) with a string and finding the string given the
constant. However this is highly delicate code that is extremely prone
to stack overflows and off-by-one's due to requiring the developer to
always remember to update the array size constant and to do so correctly
which, as shown by example, is never a good idea.b

The original goal of this code was to try to implement lookups in O(1)
time without a linear search through the message array. Since this code
is used 99% of the time for debugs, it's worth the 5-6 additional cmp's
worst case if it means we avoid explitable bugs due to oversights...

66e78ae64b *: update thread_add_* calls
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.

ffa2c8986d *: remove THREAD_ON macros, add nullity check
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.
