1. Added isis with different vrf and it's dependecies.
2. Added new vrf leaf in yang.
3. A minor change for IF_DOWN_FROM_Z passing argrument is
replaced with ifp pointer in api "isis_if_delete_hook()".
4. Minor fix in the isisd spf unit test.

1. Created a structure "isis master".
2. All the changes are related to handle ISIS with different vrf.
3. A new variable added in structure "isis" to store the vrf name.
4. The display commands for isis is changed to support different VRFs.

This is an implementation of the IS-IS SR draft [1] for FRR.
The following features are supported:
* IPv4 and IPv6 Prefix-SIDs;
* IPv4 and IPv6 Adj-SIDs and LAN-Adj-SIDs;
* Index and absolute labels;
* The no-php and explicit-null Prefix-SID flags;
* Full integration with the Label Manager.
Known limitations:
* No support for Anycast-SIDs;
* No support for the SID/Label Binding TLV (required for LDP interop).
* No support for persistent Adj-SIDs;
* No support for multiple SRGBs.

Rearrange the isisd northbound callbacks as following:
* isis_nb.h: prototypes of all northbound callbacks.
* isis_nb.c: definition of all northbound callbacks and their
associated YANG data paths.
* isis_nb_config.c: implementation of YANG configuration nodes.
* isis_nb_state.c: implementation of YANG state nodes.
* isis_nb_notifications.c: implementation of YANG notifications.
This should help to keep to code more organized and easier to
maintain.
No behavior changes intended.

Historically, isisd has been carrying around its own red-black tree to
manage its LSP DB in. This replaces that with the newly-added
DECLARE_RBTREE_*. This allows completely removing the dict_* code.

A while ago all FRR configuration commands were converted to use the
QOBJ infrastructure to keep track of configuration objects. This
means the configuration lock isn't necessary anymore because the
QOBJ code detects when someones tries to edit a configuration object
that was deleted and react accordingly (log an error and abort the
command). The possibility of accessing dangling pointers doesn't
exist anymore since vty->index was removed.
Summary of the changes:
* remove the configuration lock and the vty_config_lockless() function.
* rename vty_config_unlock() to vty_config_exit() since we need to
clean up a few things when exiting from the configuration mode.
* rename vty_config_lock() to vty_config_enter() to remove code
duplication that existed between the three different "configuration"
commands (terminal, private and exclusive).
Configuration commands converted to the new northbound model don't
need the configuration lock either since the northbound API also
detects when someone tries to edit a configuration object that
doesn't exist anymore.

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.

FRR_DAEMON_INFO should now contain an array of 'frr_yang_module_info'
structures describing the YANG modules implemented by the daemon.
This array will be used by frr_init() function to load all YANG modules
and initialize the northbound callbacks during the daemon initialization.

Remove isis_vty.c and create three new files isis_vty_common.c,

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.
