If a command is put into the VIEW_NODE, it is going into the
ENABLE_NODE as well. This is especially true for show commands.
As such if a command is in both consolidate it down to VIEW_NODE.

Finally, this disables the config editing lock for isisd. It also
enables deprecation warnings for the lib/ and isisd/ to catch accidental
uses of vty->index.

This converts all uses of vty->index over to qobj. With this, isisd now
supports concurrent configuration editing as there are no more unsafe

icc (the Intel C Compiler) "knows" that assert() can be disabled by
setting specific optimisation flags, and therefore emits a warning about
missing a return value after an "always-error" assert.
Workaround by returning a value - this probably needs discussion and a
better fix (for all places where the code needs to abort due to internal
errors).

Since recently zebra uses only the ZEBRA_REDISTRIBUTE_* messages
to advertise redistributed routes to its clientes. Now the old
ZEBRA_IPV*_ROUTE_* messages are only used for client->zebra communication.

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.

A newly-created circuit will be in enabled state but have neither IPv4
nor IPv6 configured. The logic in isis_circuit_af_set assumed that
"enabled" is equivalent to "ip || ipv6".
This is the only place where this distinction is currently relevant, as
the CLI won't allow enabling an interface without enabling either IPv4
or IPv6; and it will also disable a circuit when both are deconfigured.

Between the awkwardly managed CSM and the tacked-on IPv6 support, the
simplified logic to setup a circuit wasn't quite right.
Note that the API essentially allows creating a circuit without enabling
either IPv4 or IPv6. This wasn't possible before and probably breaks
isisd in 'interesting' ways. The CLI won't do this, so it's only an
issue when adding on other configuration mechanisms.
