Adds macvtap support

The current logic handles only VFs with direct vnic-type.
This fix will add support for VFs with macvtap vnic-type,
By checking the relevant upper_macvtap directory.

Fix handling of CIDR in allowed address pairs

A CIDR in allowed address pairs would screw up
the calculation of remote security group member
IP addresses due to a call that assumed each entry
was an IP. This patch fixes that an adds a remote
security group reference to the address pairs SG
test case to exercise this code-path.

NSX: Fix foreign key constraint delete provider network

The cascade delete on the tz_network_bindings table is not
taking effect with the NSX plugin. In order to fix this, this
will require a db migration. This patch allows us to provide a
fix for this by deleting the tz_network_bindings within a transaction
to avoid the foreign key constraint. This patch fixes it this way so
that it can be backported to icehouse. Later a patch will be pushed with a
migration which corrects the db schema.

Fix incorrect int/tuple comparison during binary search

The code contains an incorrect int/tuple comparison during the binary
search, which completely breaks the "priority" feature.
(Apparently python2 thinks int < tuple is not an error and always True.)

Support pudb as a different post mortem debugger

Post mortem debugger starts pdb at the assert failure place
when OS_POST_MORTEM_DEBUGGER is set and an exception or assert
failure happens.

This patch adds a neutron env variable OS_POST_MORTEM_DEBUGGER
to allow invocation of pudb instead of pdb. pudb module is not
a hard requisite as it will be only imported if you set
OS_POST_MORTEM_DEBUGGER=pudb.

The old OS_POST_MORTEM_DEBUG env variable is removed now.

Fix PYTHONHASHSEED bugs in test_security_groups_rpc

This fixes the test_security_groups_rpc unit test that breaks with a
randomized PYTHONHASHSEED (see the bug report).

The test assumed that several Dicts had elements in a particular order.
Found with PYTHONHASHSEED=2701526934.

The fix refactors the test case by using an OrderedDict instead of a Dict.
Or in the case of the regex strings, injecting different values depending
on the order of the devices2 and devices3 Dicts.

An upstream spelling mistake is also addressed in this patch.

Partial-bug: #1348818

Note: There are several other unrelated unit tests that also break with a
randomized PYTHONHASHSEED, but they are not addressed here. They will be
addressed in separate patches.

Delete FIP namespace when last VM is deleted

On a compute node when the last VM with a floating IP association
is deleted, the L3 agent did not delete the fip namespace. However
the api server has already deleted the fip agent external gateway
port from the database.

This problem is happening on DVRs because the deletion of a VM port,
in addition to a floating IP disassociation, may also result in the
removal of the external gateway port binding AND the removal of the
fip agent external gateway port.

When the L3 agent is handling a routers_updated notification, it is
not processing floating ip address updates when the router has both
a floating ip disassociated and a external gateway port deleted.
This patch corrects this problem.

Tighten up try/except block around rpc call

The try is too broad.  This commit moves code outside of the try block
where exceptions are not expected to be raised.  This only leaves the
rpc call in the current code.  In legacy code, there used to be more
but now this code merely queues updates for workers to handle
in other threads.

Drop RpcProxy usage from bigswitch plugin

This patch drops the usage of the RpcProxy compatibility class from
the bigswitch plugin.  The equivalent usage of oslo.messaging APIs is
now used instead.

Note that there is one very minor functional change included.  The
previous code set the base version to '1.1'.  It should be '1.0'.  The
proper pattern to use is to set the base version on the client side to
be the initial version of the API (X.0).  Then, any methods that
require a newer version need to specify it.  In this case, verison
'1.1' was the security group methods, and those specify '1.1' as you
would expect.

Part of blueprint drop-rpc-compat.

Fix metadata proxy start problem for v6-v4 network

Commit 1b66e11b5d8c0b3de0610ca02c3e10b6f64ae375 introduces
a new problem that metadata proxy will not be started when
an isolated network contains ipv6 subnet with dhcp enabled
and a ipv4 subnet.

This fix separates the checks to enable dhcp and enable metadata
so metadata proxy can be started if there is ipv4 subnet exists
in the network with metadata enabled.
