We had both and the only difference was that the latter also included
information about multifunction setting.  The problem with that was that
we couldn't use functions made for only one of the structs (e.g.
parsing).  To consolidate those two structs, use the one in virpci.h,
include that in domain_conf.h and add the multifunction member in it.

If a pci address had a function number out of range, the error message
would be:

  Insufficient specification for PCI address

which is logged by virDevicePCIAddressParseXML() after
virDevicePCIAddressIsValid returns a failure.

This patch enhances virDevicePCIAddressIsValid() to optionally report
the error itself (since it is the place that decides which part of the
address is "invalid"), and uses that feature when calling from
virDevicePCIAddressParseXML(), so that the error will be more useful,
e.g.:

  Invalid PCI address function=0x8, must be <= 7

Previously, virDevicePCIAddressIsValid didn't check for the
theoretical limits of domain or bus, only for slot or function. While
adding log messages, we also correct that ommission. (The RNG for PCI
addresses already enforces this limit, which by the way means that we
can't add any negative tests for this - as far as I know our
domainschematest has no provisions for passing XML that is supposed to
fail).

Note that virDevicePCIAddressIsValid() can only check against the
absolute maximum attribute values for *any* possible PCI controller,
not for the actual maximums of the specific controller that this
device is attaching to; fortunately there is later more specific
validation for guest-side PCI addresses when building the set of
assigned PCI addresses. For host-side PCI addresses (e.g. for
<hostdev> and for network device pools), we rely on the error that
will be logged when it is found that the device doesn't actually
exist.

When we edit a negative controller address number to a device,
some of them will auto generate a controller with invalid index
number. This will make guest disappear after restart libvirtd.
Instead of allowing negative number for controller index, we
should forbid negative number in these place (we did this before,
but after f18c02ec, virStrToLong_ui changed to allow negative
number). Therefore switch to virStrToLong_uip in these places.

Currently it is not possible to determine the speed of an interface
and whether a link is actually detected from the API. Orchestrating
platforms want to be able to determine when the link has failed and
where multiple speeds may be available which one the interface is
actually connected at. This commit introduces an extension to our
interface XML (without implementation to interface driver backends):

  <interface type='ethernet' name='eth0'>
    <start mode='none'/>
    <mac address='aa:bb:cc:dd:ee:ff'/>
    <link speed='1000' state='up'/>
    <mtu size='1492'/>
    ...
  </interface>

Where @speed is negotiated link speed in Mbits per second, and state
is the current NIC state (can be one of the following:  "unknown",
"notpresent", "down", "lowerlayerdown","testing", "dormant", "up").

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

This function really should have been taking virDevicePCIAddress*
instead of the inefficient virDevicePCIAddress (results in copying two
entire structs onto the stack rather than just two pointers), and
returning a bool true/false (not matching is not necessarily a
"failure", as a -1 return would imply, and also using "if
(!virDevicePCIAddressEqual(x, y))" to mean "if x == y" is just a bit
counterintuitive).

* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/;  If/.  If/

This function is needed by the network driver in a later commit.
It is useful in functions like networkNotifyActualDevice and
networkReleaseActualDevice

Move the functions the parse/format, and validate PCI addresses to
their own file so they can be conveniently used in other places
besides device_conf.c

Refactoring existing code without causing any functional changes to
prepare for new code.

This patch makes the code reusable.
