The required packages list should be easier to parse. Updated the style so it's more similar to the ``./configure`` style later in the document.

The warning string which appears when the users executes 'no (enable)
password' was moved into command.h and declared as a constant named
'NO_PASSWD_CMD_WARNING'.
This avoids duplicate code and makes it easy to change the warning
message in all places at once.

When the user executes one of the commands 'no password' or 'no enable
password', a warning message gets shown to inform the user of the
security implications.
While the current implementation works, a warning message gets printed
once for each daemon, which can lead to seeing the same message many
times. This does not affect functionality, but looks like an error to
the user as it can be seen within issue #1432.
This commit only prints the warning message inside lib when vtysh
dispatch is not being used. Additionally, the warning message was copied
into the vtysh command handlers, so that they get printed exactly once.

Cleanup the pim->rpf_hash after upstream cleanup is done
since upstream cleanup uses the rpf_hash to cleanup itself.

The pim_upstream_free command was leaving slag by
not deleting data associated with the upstream
data structure. Modify the code to explicitly free
all data associated with an upstream on a pim instance
deletion event. Additionally the end result is that
the pim_upstream_free command is not needed anymore

Ensure that when EVPN routes are imported into a VRF as IPv4 routes,
the NEXT_HOP attribute is set. In the absence of this, this attribute
is currently not generated when advertising the route to peers in the
VRF. It is to be noted that the source route (the EVPN route) will only
have the MP_REACH_NLRI attribute that contains the next hop in it.

Imported routes in a VRF routing table have a reference to their parent
route entry which resides in the EVPN or IPVPN routing table. Ensure that
this reference uses appropriate locking so that the parent entry doesn't
get freed prematurely.

(cherry picked from commit 13cb6b22ba9d558b1b4a1e8752f63f13242462a7)
Conflicts:
bgpd/bgp_mplsvpn.c
Ticket: CM-20471
Testing Done:
a) Ran vrf_route_leak tests without fix and hit crash, ran twice with fix
and did not see the crash.
b) Ran evpn-smoke and ensured there were no new failures.
The previous implementation of bgp_peer_lookup_next did not consider the
internal ordering of peers when using peer groups, which led to all
standalone peers being skipped that had a lower IP address than the
highest IP address of a peer belonging to a group.
As the ordering of peers can not be arbitrary due to SNMP requiring
increasing OIDs when walking an OID tree, this commit fixes the bug by
properly looping through all peers and detecting the next highest IP
address.
Additionally, this commit improved both bgp_peer_lookup_next and
peer_lookup_addr_ipv4 by using the socketunion stored within the peer
struct (peer->su) instead of calling inet_pton for each peer during
comparison.

When bgp is thinking about opening a connection to a peer,
if we are connected to zebra, allow that to influence our
decision to start the connection.
Found Scenario:
Both bgp and zebra are started up at the same time. Zebra is
being used to create the connected route through which bgp
will establish a peering relationship. The machine is a
bit loaded due to other startup conditions and as such bgp
gets to the connection stage here before zebra has installed
the route. If bgp does not respect zebra data when it does
have a connection then we will attempt to connect. The
connect will fail because there is no route. At that time
we will go into the connect timeout(2 minutes) and delay
connection.
What this does. If we have established a zebra connection and
we do not have a clear path to the destination at this point
do not allow the connection to proceed.
