Richard W.M. Jones 1d8d4f86b6 Standardize use of header files, making internal.h primary.
* qemud/internal.h, qemud/qemud.h: Rename this file so it
	doesn't conflict with src/internal.h.
	* HACKING: Document how header files should be used.
	* qemud/Makefile.am: Add src/ directory to includes.
	* qemud/event.c, qemud/mdns.c, qemud/qemud.c, qemud/remote.c,
	qemud/remote_protocol.c, qemud/remote_protocol.h,
	qemud/remote_protocol.x, src/buf.c, src/libvirt.c,
	src/nodeinfo.c, src/qemu_conf.c, src/qemu_driver.c,
	src/stats_linux.c, src/storage_backend.c, src/storage_backend_fs.c,
	src/storage_backend_iscsi.c, src/storage_backend_logical.c,
	src/storage_conf.c, src/storage_driver.c, src/util.c,
	src/util.h, src/virsh.c, src/virterror.c, src/xend_internal.c,
	src/xml.c, tests/reconnect.c, tests/xmlrpctest.c,
	tests/qparamtest.c: Standardize	use of header files.
	* docs/*, po/*: Rebuild docs.

<h1>Network management architecture</h1>
<h2>Architecture illustration</h2>
<p>
The diagrams below illustrate some of the network configurations
enabled by the libvirt networking APIs
</p>
<ul>
<li><strong>VLAN 1</strong>. This virtual network has connectivity
to <code>LAN 2</code> with traffic forwarded and NATed.
</li>
<li><strong>VLAN 2</strong>. This virtual network is completely
isolated from any physical LAN.
</li>
<li><strong>Guest A</strong>. The first network interface is bridged
to the physical <code>LAN 1</code>. The second interface is connected
to a virtual network <code>VLAN 1</code>.
</li>
<li><strong>Guest B</strong>. The first network interface is connected
to a virtual network <code>VLAN 1</code>, giving it limited NAT
based connectivity to LAN2. It has a second network interface
connected to <code>VLAN 2</code>. It acts a router allowing limited
traffic between the two VLANs, thus giving <code>Guest C</code>
connectivity to the physical <code>LAN 2</code>.
</li>
<li><strong>Guest C</strong>. The only network interface is connected
to a virtual network <code>VLAN 2</code>. It has no direct connectivity
to a physical LAN, relying on <code>Guest B</code> to route traffic
on its behalf.
</li>
</ul>
