xenserver: Update all external_ids in tap interfaces.
Commit 400430 "xenserver: Give tap devices iface-ids." copies the
iface-id from vifs to their related tap device. It turns out this
is not sufficient, so this commit copies all relevant external_ids
over.

When "configure"'s environment contains KSRC, "configure" would use it in

configure: Remove "26" from Linux variable names.
OVS used to support Linux 2.4 and Linux 2.6, but now it only supports
Linux 2.6. Linux 3.0 is coming up, and it's just an evolution of 2.6, so
OVS should stop referring to it as "2.6".
This takes a first step by removing "26" from internal variable names.
There should be no user-visible changes.

Avoid inserting duplicate iptables rules when restarting vswitch.
On startup, some OVS initscripts insert an iptables rule to allow GRE
traffic (because GRE support is an important OVS feature). I noticed that,
each time I restarted OVS, this added another GRE-related rule to the
iptables chain. This is wasteful, because each additional rule increases
the time it takes to process a packet in the IP stack.
This commit avoids the problem by inserting an iptables rule when there
isn't already an appropriate rule. It also avoids inserting an iptables
rule if the iptables policy is ACCEPT, meaning that packets are accepted
by default; in such a case, if the GRE packet would be dropped, it is
because the system administrator made that decision explicitly.

ovsdb-idl: Plug hole in state machine.
The state machine didn't have a proper state for "not yet committed or

state TXN_UNCOMMITTED to the state machine.
