Back when I put this together in 2015, ISO C11 was still reasonably new
and we couldn't require it just yet. Without ISO C11, there is no
"good" way (only bad hacks) to require a semicolon after a macro that
ends with a function definition. And if you added one anyway, you'd get
"spurious semicolon" warnings on some compilers...
With C11, `_Static_assert()` at the end of a macro will make it so that
the semicolon is properly required, consumed, and not warned about.
Consistently requiring semicolons after "file-level" macros matches
Linux kernel coding style and helps some editors against mis-syntax'ing
these macros.

We should never attempt to remove a list item in the "del" callback
of the list. This is already performed by the list_delete() function,
doing it twice leads to crashes or memory corruption.
Introduce the offset_list_free() function so that we can separate the
removal and deallocation of offset lists into separate functions,
without code duplication. offset_list_del() will be used by the
northbound callbacks to remove offset lists, while offset_list_free()
will be used by rip_clean() to clean up all RIP offset lists using
list_delete(). Do the same for ripngd.
This is a fallout from the ripd/ripngd northbound conversion.

This is the last step to make ripngd ready for multi-instance
support.
Remove the ripng global variable and add a "ripng" parameter
to all functions that need to know the RIPng instance they are
working on. On some functions, retrieve the RIPng instance from
the interface variable when it exists (this assumes interfaces can
pertain to one RIPng instance at most, which is ok for VRF support).
In preparation for the next commits (VRF support), add a "vrd_id"
member to the ripng structure, and use ripng->vrf_id instead of
VRF_DEFAULT wherever possible.

Remove the ripng_offset_list_set() and ripng_offset_list_unset()
functions since they set/unset multiple configuration options at the
same time. The northbound callbacks need to set/unset configuration
options individually.
The frr-ripngd YANG module models the "offset-list" command using a
list keyed by the 'interface' and 'direction' leafs. One important
detail is that the IFNAME parameter is optional, and when it's not
present it means we want to match all interfaces. This is modeled
using an interface name of '*' since list keys are mandatory leafs
by definition in YANG.

The following types are nonstandard:
- u_char
- u_short
- u_int
- u_long
- u_int8_t
- u_int16_t
- u_int32_t
Replace them with the C99 standard types:
- uint8_t
- unsigned short
- unsigned int
- unsigned long
- uint8_t
- uint16_t
- uint32_t

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.

This allows frr-reload.py (or anything else that scripts via vtysh)
to know if the vtysh command worked or hit an error.

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.

* {ospf6d,ripngd}/*: Finish job of marking functions as static, or
exporting declarations for them, to quell warning noise with
Quagga's GCC default high-level of warning flags. Thus allowing
remaining, more useful warnings to be more easily seen.
|
|
* (global): Fix up list loops to match changes in lib/linklist,
and some basic auditing of usage.
* configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES
* HACKING: Add notes about deprecating interfaces and commands.
* lib/linklist.h: Add usage comments.
Rename getdata macro to listgetdata.
Rename nextnode to listnextnode and fix its odd behaviour to be
less dangerous.
Make listgetdata macro assert node is not null, NULL list entries
should be bug condition.
ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use
with for loop, Suggested by Jim Carlson of Sun.
Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the
"safety" of previous macro.
LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to
distinguish from the similarly named functions, and reflect their
effect better.
Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section
with the old defines which were modified above,
for backwards compatibility - guarded to prevent Quagga using it..
* lib/linklist.c: fix up for linklist.h changes.
* ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single
scan of the area list, rather than scanning all areas first for
INTER_ROUTER and then again for INTER_NETWORK. According to
16.2, the scan should be area specific anyway, and further
ospf6d does not seem to implement 16.3 anyway.
