Now that we display hostnames in 'show ip bgp summary' it is really easy

'neighbor x.x.x.x weight' was implemented as a per-peer knob instead of
a per-peer per-afi-safi option. This makes it configurable per-peer
per-afi-safi so that we can do things like soft clear that afi/safi when
weight is modified.
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.

The RESTRICTED_NODE command is not used, introduces code
complexity and provides no additional levels of security.
The only way to get into RESTRICTED_NODE is to add, under
vty configuration the command 'anonymous restricted', and
then telnet to a daemon, provide a password, then type
'enable' and fail to enter the password three times.
Then the user can enter a very limited set of commands to
monitor bgp and only bgp behavior.
This commit removes both the RESTRICTED_NODE usage as well
as the lib/* usage of the code

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.

Found that original fix for CM-10113 had a significant flaw, that
by deriving the bgp instance from the vty->index, if a clear ip bgp
command was entered from a vty index other then bgp, a crash occurred.
This fix passes the bgp->name to the clear functions so the correct
instance can be derived. Tested manually in both the CM-10113 case
as well as the problem discovered while testing CM-11480.

To make BGP configuration as simple as possible, assume the capability
extended-nexthop to be default for interface neighbors. Also allow the
ability to specify remote-as on the same line as neighbor interface to
make BGP unnumbered configuration a single line.
One corner case. This is the first feature for which the default for a
member is different from the default for a peer-group. Since advertising
the capability is only done for interface neighbors, the capability is
not set for the peer-group, but is automatically set for interface
neighbors that belong to that peer-group. So, if you want to disable the
advertisement of this capability for an interface neighbor, you must
do it per each interface neighbor.
The patch is more complicated than it needs to be due to the handling
of quagga reload and appropriate updates to the show running output.

Useful when the BGP neighbors are over tunnels that have large
differences in geographic distances and RTTs. Especially useful
for DMVPN setups to allow preferring closes hub.
The parameter is added as new alias command as otherwise it seems
the command parser is not able to match it properly (it seems
merging is done for the various 'set metric' route-map objects in
different routing engines). For same reason also they are listed
as three separate options: optional +/- seems not possibly easily.

* md5.h: signedness of caddr_t is implementation specific, change to an
explicit (uint_8 *), fix sign/unsigned comparison warnings.
* vty.c: (vty_log_fixed) const on level is well-intentioned, but not going
to fly given iov_base.
* workqueue.c: ALL_LIST_ELEMENTS_RO tests for null pointer, which is always
true for address of static variable. Correct but pointless warning in
this case, but use a 2nd pointer to shut it up.
* ospf6_route.h: Add a comment about the use of (struct prefix) to stuff 2
different 32 bit IDs into in (struct ospf6_route), and the resulting
type-pun strict-alias breakage warnings this causes. Need to use 2
different fields to fix that warning?
general:
* remove unused variables, other than a few cases where they serve a
sufficiently useful documentary purpose (e.g. for code that needs
fixing), or they're required dummies. In those cases, try mark them as
unused.
* Remove dead code that can't be reached.
* Quite a few 'no ...' forms of vty commands take arguments, but do not
check the argument matches the command being negated. E.g., should
'distance X <prefix>' succeed if previously 'distance Y <prefix>' was set?
Or should it be required that the distance match the previously configured
distance for the prefix?
Ultimately, probably better to be strict about this. However, changing
from slack to strict might expose problems in command aliases and tools.
* Fix uninitialised use of variables.
* Fix sign/unsigned comparison warnings by making signedness of types consistent.
* Mark functions as static where their use is restricted to the same compilation
unit.
* Add required headers
* Move constants defined in headers into code.
* remove dead, unused functions that have no debug purpose.

To be backwards compatible we should silently accept the "exact" keyword
here
Instead of turning on IPv6 RA on every interface as soon as it has an IPv6
address, only enable it upon configuration of BGP neighbor. When the BGP
neighbor is deleted, signal that RAs can be turned off.
To support this, introduce new message interaction between BGP and Zebra.
Also, take appropriate actions in BGP upon interface add/del since the
unnumbered neighbor could exist prior to interface creation etc.
Only unnumbered IPv6 neighbors require RA, the /30 or /31 based neighbors
don't. However, to keep the interaction simple and not have to deal with
too many dynamic conditions (e.g., address deletes or neighbor change to/from
'v6only'), RAs on the interface are triggered upon any unnumbered neighbor
configuration.
BGP-triggered RAs will cause RAs to be initiated on the interface; however,
if BGP asks that RAs be stopped (upon delete of unnumbered neighbor), RAs
will continue to be exchanged if the operator has explicitly enabled.
