gre: Add support for path MTU discovery.
This allows path MTU discovery to properly work when used with
bridging. While there was previously support for PMTUD it used
the kernel's IP stack. This works fine for routing but when
bridging it is possible that a complete network is operating over
the bridge that the kernel has no knowledge of and the ICMP
fragmentation needed packets are lost.
When a packet arrives that is above the MTU of the tunnel, an
ICMP message is synthesized and send back on the device that the
original packet came from. This does not rely on the kernel IP
stack and is therefore independent of the routing table. Both
IPv4 and IPv6 are supported, including over VLANs. Other types
of packets that are over the MTU are encapsulated and the outer
packets are fragmented.
This entire functionality is a layer violation since bridging
operates at layer 2 and fragmentation is a function of layer 3.
For this reason it is possible to disable PMTUD, which will
provide complete transparency but will cause the outer IP packets

This also resolves an inconsistency between tunnels set up using
the ioctl and using Netlink. The ioctl version would force PMTUD

ovs-brcompatd: Delete Bridge record when deleting a bridge.
del_bridge() removed the reference to the Bridge record from the
Open_vSwitch table, but it didn't actually delete the Bridge record itself.
This fixes the problem.
Bug #2425.

ovs-brcompatd: Fix dangling reference in del_port().
Until now, del_port() was deleting Interface records without deleting the
Port record that referred to them. OVSDB rejected that because it would
have caused a dangling reference from the Port to the Interfaces. This
commit fixes the problem.

Fix excessive white space in manpages.
In nroff manpages, a blank line adds vertical white space. When this is
followed by another command that also starts a new paragraph, the result
is a vertical skip twice as big as the normal inter-paragraph gap. The
solution is to use a line that contains just "." for white space within
the manpage, instead of a blank line. The resulting manpages look better.
