Introduce frr-interface.yang, which defines a model for managing FRR
interfaces.
Update the 'frr_yang_module_info' array of all daemons that will
implement this module.
Add automatically generated stub callbacks in if.c. These callbacks will
be implemented in the following commit.

Modify if_lookup_by_index to accept a VRF_UNKNOWN
as a vrf_id. This will cause it to look in all
vrf's for the interface pointer.
Subsequently all if_XXXX functions that call this function
will also get this behavior.
VRF_UNKNOWN *should* not be used for interface creation
as that this will break some core assumptions.
This work is part of allowing vrf route leaking. Currently
it is possible to create a route in the linux kernel that has
a nexthop across vrf boundaries.

This improves code readability and also future-proofs our codebase
against new changes in the data structure used to store interfaces.
The FOR_ALL_INTERFACES_ADDRESSES macro was also moved to lib/ but
for now only babeld is using it.

Performance tests showed that, when running on a system with a large
number of interfaces, some daemons would spend a considerable amount
of time in the if_lookup_by_index() function. Introduce a new rb-tree
to solve this problem.
With this change, we need to use the if_set_index() function whenever
we want to change the ifindex of an interface. This is necessary to
ensure that the 'ifaces_by_index' rb-tree is updated accordingly. The
return value of all insert/remove operations in the interface rb-trees
is checked to ensure that an error is logged if a corruption is
detected.

IFINDEX_DELETED is not necessary anymore as we moved from a global
list of interfaces to a list of interfaces per VRF.

This is an important optimization for users running FRR on systems with
a large number of interfaces (e.g. thousands of tunnels). Red-black
trees scale much better than sorted linked-lists and also store the
elements in an ordered way (contrary to hash tables).
This is a big patch but the interesting bits are all in lib/if.[ch].

The if_update function was taking the interface name as
input and reapplying it, using strncpy to reapply the name.
This has several issues. strncpy should not be used
to copy memory in place. The second issue is that
the interface name is not actually changing when we
update interface to be in the new vrf.
Since every usage of if_update was just reapplying the same
name the interface actually had, just remove that part of
the function and rename it to if_update_to_new_vrf
to represent what it is actually doing.

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.

This moves all install_element calls into the file where the DEFUNs are
located. This fixes several small related bugs:
- ospf6d wasn't installing a "no interface FOO" command
- zebra had a useless copy of "interface FOO"
- pimd's copy of "interface FOO" was not setting qobj_index, which means
"description LINE" commands would fail with an error
The next commit will do the actual act of making "foo_cmd" static.

We can't use if_lookup_prefix() in rip_update_process() because this
function uses prefix_cmp() internally to try matching an interface
address to a static neighbor's address.
Since prefix_cmp() tries to match exact prefixes, if_lookup_prefix()
was always returning NULL.
What we really need here is to use prefix_match(), which checks if
one prefix includes the other (e.g. one /24 interface including a /32
static neighbor's address). The fix then is to replace the call to
if_lookup_prefix() and use if_lookup_address() instead, which uses
prefix_match() internally.
Fixes IxANVL RIP test 17.1

Since we have autoconf results from a wide swath of target platforms, we

This is a rather large mechanical commit that splits up the memory types
defined in lib/memtypes.c and distributes them into *_memory.[ch] files
in the individual daemons.
The zebra change is slightly annoying because there is no nice place to
put the #include "zebra_memory.h" statement.
bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the
library for its own use. This is bad practice and would break when the
memtype are made static.

This removes the BSD specific usage of struct sockaddr_dl
hardware address. This unifies to use explict hw_addr member for
the address, and zebra specific enumeration for the link layer
type.
Additionally the zapi is updated to never send platform specific
structures over the wire, but the ll_type along with hw_addr_len
and hw_addr are now sent for all platforms.
Based on initial work by Paul Jakma.
