Changed a sitevar variable name to max_sliver_lifetime. It actually limits the sliver lifetime not ticket lifetime which expires shortly.

Added PolicyExists API in GeniXML.pm.in and defined namespace constants in GeniUtil.pm.in and fixed a minor bug in serializing extensions in Genicredential.

Check for READINFO rather than MODIFYINFO.  AnalBoy strikes again.

We introduced this port or an older version of GD long ago to get around an
incompatibility with perl.  Our perl has since moved on and we no longer
need this.  To be safe, we still install this on 4.x-based installs (though
I am sure many, many other things would break if someone tried to install
Emulab on FreeBSD 4.x now!)

1) max_ticket_lifetime : It determines how long a sliver can live. Default is set to 90 days.
2) max_components : It limits the number of components that can be requested/allocated to a user. Default value -1 indicates that there is no limit. any number of components can be requested/allocated.

Added FindNodesNS function, that finds nodes based on XPATH query in the specified namespace and not in the node namespace.

To get a backslash into the DB (e.g., into table_regex) you have to
use FOUR backslashes in the perl script.

Also, further reorg of rc.mkelab as I stuble my way toward a reasonable
organization.

Made set-elabinelab-attribute set the attribute for all roles (nodes).
Added a net command set-elabinelab-role-attribute to set it for a single role.
Ditto for unset.

The common case was setting a "global" attribute and it was tedious to give
individual commands for boss, ops, fs, etc.

A new feature of mkextrafs (-2) is rather critical to the new disk layout.
Rather than support old/new style disk layouts, just copy over a new mkextrafs
(as we do with rc.mkelab) so that images without the new version of the
script will work as boss/ops.

If new elabinelab_attribute has same role/key/order, replace any existing
such element.  This preserves what we have set in the DB as the unique key.

Add all the NS parsing and DB foo.

Always checks to see if directory might be a mount point and deals with it.

Just avoids installing packages like the ops version.
