This allows nsverify to be built on FreeBSD 7+.  Based on patches from John
Hickey <jhickey@isi.edu> and Serge van Ginderachter <serge@vanginderachter.be>,
thanks guys!

I also moved all the logic for downloading/patching the tarball from the
GNUmakefile into ns-patch.sh to bring this in line with our other third-party
packages that do the same.  This is in pursuit of one day having a GUDS
(Grand Unified Download Script).

a merge.

This reverts commit efdf34a0.

Attempt to solve some problems with trunk creation by reverting
this change. It's not *certain* that this change is at fault, but
I want to factor out some possible causes

trivial link betweem two VMs on the same phys host. There is no vlan,
but we can fake things enough so that everything looks as it should by
creating a bridge device with no vlan devices in it.

This reverts commit a31f1a5b.

this, you could fix a VM to specific physical node, but not to another
node in the topology. This change allows you to do something like the
following:

set n1 [$ns node]
set n2 [$ns node]
set n3 [$ns node]
set v1 [$ns node]
set v2 [$ns node]
set v3 [$ns node]

tb-set-hardware $v1 pcvm
tb-set-hardware $v2 pcvm
tb-set-hardware $v3 pcvm
# Fix the VMs to other nodes in the topology.
tb-fix-node $v1 $n1
tb-fix-node $v2 $n2
tb-fix-node $v3 $n3

# This mix requires vlan encap all around
tb-set-vlink-emulation "vlan"

# A link between the two phys nodes.
set link0 [$ns duplex-link $n1 $n2 100Mb 0ms DropTail]

# A link between the two VMs.
set link1 [$ns duplex-link $v1 $v2 10Mb 0ms DropTail]

# A lan of three physical nodes.
set lan0 [$ns make-lan "$n1 $n2 $n3" 100Mb 0ms]

# A lan of three VMs
set lan1 [$ns make-lan "$v1 $v2 $v3" 10Mb 0ms]

# Lets mix things up.
set link2 [$ns duplex-link $n1 $v2 10Mb 0ms DropTail]
set lan2 [$ns make-lan "$n1 $v2 $n3" 10Mb 0ms]

tb-set-node-os $n1 FEDORA8-OVZ-STD
tb-set-node-os $n2 FEDORA8-OVZ-STD
tb-set-node-os $n3 FEDORA8-OVZ-STD
tb-set-node-os $v1 OPENVZ-STD

so that we can tell the user to do something. For example, after
installing xerces, we need the user to reconfig/rebuild the object
tree and restart the installation.

It used to say FBSDVERSION != 6, but that was when there was only 4 and 6.

Delay agent won't build on FreeBSD 8.x right now due to dummynet API changes.
Not even sure we will bother to fix this since we have a newer, more OS
independent agent.

"make -C dir foo" != "cd dir && make foo"
PWD in a shell script evaluates different, presumably because it is
inherited from the invoking shell/make.

Normalized the error message for excessive link properties and corrected the behaviour of the parser when no link properties are specified.

than earlier.

The API spec clearly states that the compression keyword is
'geni_compressed'. Changed the erroneous 'geni_compress' to the
correct keyword in GeniAM and the listresources am test script.

The main change is to add a NEWER_GCC macro, separate from NEW_GCC, to
detect GCC 4.3 and up.

This is necessary because, in GCC 4.3, hash_fun.h moved from ext/ to
backward/.  New comments in port.h give the details.

common.h, fstring.h: use NEWER_GCC to locate hash_fun.h.  port.h:
define NEWER_GCC if GCC >= 4.3.

If a request was made for a node type that was not present in the physical
topology, then the error message was, "Too much bandwidth on emulated links."
This change adds a flag in mapping_precheck() that remembers whether the
requested node type was found.  If not, then a new error message is printed
instead of the bandwidth one.

Use "uint32_t" instead of "unsigned long" for on-the-wire data.

Don't die if named is running but the pid file is gone.
Beware of more than one m2crypto .egg file installed.
Install swig if necessary when unpacking .egg

Subbosses make XMLRPC requests as the user 'elabman' which doesn't
belong to any projects, and therefore has no rights to non-global
images.  The easiset way to solve this is to run frisbeelauncher with
admin privileges when a subboss requests it.

We already check to make sure the requesting user has permission to use
the image in libosload well before we hand the request to the subboss,
so if the subboss requests the image we can trust it.

ListResources always return a string. If compression is requested the
string's contents are a base64 encoded compressed RSpec. ListResources
now takes the XML-RPC base64 result from DiscoverResources and
converts it to a string value and returns that.

It didn't fix what we thought it would fix. Check in a few generated .xsd files
