clang provides a notice about it that this p++ is useless,
because ++ would be done after the return.
From code review, I understand that p shall be incremented
for each token that is parsed from the buf. So let's keep
this intent.
Note that this commit is changing the behaviour of the source
code since from now p++ will be returned instead of p.
However, it does not hurt since the only consumer
just free() the aspath if it is parsed as as_token_unknown.
Let's be safe with a proper execution flow from now.
PS:
C reminders:
int f7(void) {
int j = 7;
return ++j; // return 8
}
int f8(void) {
int j = 7;
return j++; // return 7
}

stlv_last is initialized with the loops. No need to reset it.
Its scope is local to the use with the loops.

ei shall never be NULL once we do the lookup. If it is NULL
bad things could happen.
For instance ei->t_distribute may not be a valid reference.

nbr cannot be NULL. Doing such test does confuse clang since
we do not have execution case if nbr == NULL.

size is not used for further parsing. Keep it updated but tell
to the compiler that we know it is not used just in case one
needs to extend the parsing somedays.

tlvs is not used after extracting the last TLV. So,
let's tell to the compiler that it is expected.

Avoid show() methods from being a NULL function when it is called.
Meanwhile, I did const'ify the handlers so only its debug field can be changed.

Incomplete commands like "debug ospf6 route mem" were being ignored. The
changes in ripd and ripngd are intended to make the code easier to read,
no bugs were fixed in these two daemons.

list_free is occassionally being used to delete the
list and accidently not deleting all the nodes.
We keep running across this usage pattern. Let's
remove the temptation and only allow list_delete
to handle list deletion.

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.

The multicast boundary command must be shown after
the `ip pim sm` command. So add a new config_add_line_end
and make it the last one.

The json option for displaying a bgp table
with route Distinguishers in it was not properly
working. This code cleans this issue up.
Additionally attempt to make the code a bit
easier to read and handle.

This commit does two things:
1) Flush by proto number not string
This is useful because not all systems might have the proto
values installed, or a version of iproute2 that they might
be installed with.
2) Flush missing routes that might have been installed( eigrp
and nhrp )
