f9d9e1b4ec Mechanically rename s/ng_timeout/ng_callout/g, s/ng_untimeout/ng_uncallout/g. 
This is done to keep both versions in RELENG_5 and support both APIs.

92947dc698 Cancel pending timeout before scheduling a new one. This fixes 
item leak, I've introduced with previous change.

a6fd48812e Adapt to the new ng_timeout/ng_untimeout arguments. These now use 
the callout instead of the timeout interface.

3161f583ca Apply error and success logic consistently to the function netisr_queue() and 
its users.

netisr_queue() now returns (0) on success and ERRNO on failure.  At the
moment ENXIO (netisr queue not functional) and ENOBUFS (netisr queue full)
are supported.

Previously it would return (1) on success but the return value of IF_HANDOFF()
was interpreted wrongly and (0) was actually returned on success.  Due to this
schednetisr() was never called to kick the scheduling of the isr.  However this
was masked by other normal packets coming through netisr_dispatch() causing the
dequeueing of waiting packets.

a2931871f7 This is the netgraph node framework for the user side call control 
node for ATM. This node implements the API to the signalling services.

be4252b367 Slight cosmetic changes. 
Also introduce a macro to be called by persistent nodes to signal their
persistence during shutdown to hide this mechanism from the node author.

Make node flags have a consistent style in naming.

Document the change.

327b288e5c Convert Netgraph to use mbuf tags to pass its meta information around. 
Thanks to Sam for importing tags in a way that allowed this to be done.

Also allow the sr and ar drivers to create netgraph versions of their modules.
Document the change to the ksocket node.

efd8e7c9b6 The last argument to mtx_init() should be MTX_DEF, not 0. This is not a 
functional change since MTX_DEF happens to be defined as 0.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members 
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

fa6a7ef6e4 Process events from the ATM drivers. Carrier change and PVC change 
messages are forwarded as netgraph control messages to the node
that is connected to the manage hook. If that hook is not connected,
the event is lost. Flow control events are converted to netgraph
flow control messages and send along the hook that is connected to
the flow controlled VC. ACR change events are converted to control
messages and sent along the hook for the given VC.
