net-undefine doesn't only undefine an inactive network,
but also an active network(persistent), it just cannot
undefine a transient network.

Assign the value we're comparing:
(val = func()) < 0
instead of assigning the comparison value:
(val = func() < 0)
Both were introduced along with the code,
the TLS tests by commit bd789df in 0.9.4
net events by commit de87691 in 1.2.2.
Note that the event id type fix is a no-op:
vshNetworkEventIdTypeFromString can only return
-1 (failure) and the event is never used or
0 (the only possible event) and the value of 0 < 0 is still 0.
Instead of maintaining two very similar APIs, add the "@mac" parameter
to virNetworkGetDHCPLeases and kill virNetworkGetDHCPLeasesForMAC. Both
of those functions would return data the same way, so making @mac an
optional filter simplifies a lot of stuff.
Use virNetworkGetDHCPLeases and virNetworkGetDHCPLeasesForMAC in virsh.
The new feature supports the follwing methods:
1. Retrieve leases info for a given virtual network
2. Retrieve leases info for given network interface
tools/virsh-domain-monitor.c
* Introduce new command : net-dhcp-leases
Example Usage: net-dhcp-leases <network> [mac]
virsh # net-dhcp-leases --network default6
Expiry Time MAC address Protocol IP address Hostname Client ID or DUID

Dan Berrange suggested that using VIR_ENUM_IMPL is more compact
than open-coding switch statements, and still just as forceful
at making us remember to update lists if we add enum values
in the future. Make this change throughout virsh.
Sure enough, doing this change caught that we missed at least
VIR_STORAGE_VOL_NETDIR.

* tools/virsh-domain.c (vshDomainVcpuStateToString)

switch to enum lookup.

These all existed before virfile.c was created, and for some reason
weren't moved.
This is mostly straightfoward, although the syntax rule prohibiting
write() had to be changed to have an exception for virfile.c instead
of virutil.c.
This movement pointed out that there is a function called
virBuildPath(), and another almost identical function called
virFileBuildPath(). They really should be a single function, which
I'll take care of as soon as I figure out what the arglist should look
like.
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.
After we switched to C99 initialization, I noticed there were many
places where the specification of .flags parameter differed. After
going through many options and deciding whether to unify the
initialization to be '.flags = 0' or '.flags = VSH_OFLAG_NONE', I
realized both can be removed and it makes the code easier to go
through.
This patch changes whitespace and the length of the separation line from
this format:
$ virsh net-list --all
Name State Autostart Persistent
--------------------------------------------------
default inactive yes yes
to
$ virsh net-list --all
Name State Autostart Persistent
----------------------------------------------------------
default inactive yes yes
to match the output of virsh list.
This command uses the new virNetworkUpdate() API to modify an existing
network definition, and optionally have those modifications take
effect immediately without restarting the network.
An example usage:
virsh net-update mynet add-last ip-dhcp-host \
"<host mac='00:11:22:33:44:55' ip='192.168.122.45'/>" \
--live --config
If you like, you can instead put the xml into a file, and call like
this:
virsh net-update mynet add ip-dhcp-host /tmp/myxml.xml
--live --config
virsh will autodetect whether the argument is itself an xml element,
or if it's a file, by looking at the first character - the first
character of an xml element is always "<", and the first character of
a file is almost always *not* "<" (in the rare case that it is, the
user could specify "./<filename...").
A --parent-index option is also available (to give the index within a
list of parent objects, e.g. the index of the parent <ip> element when
updating ip-dhcp-host elements), but is optional and at least for now
will probably be used rarely.
--live, --config, and --current options - if you specify --live, only
the live state of the network will be updated. If you also specify
--config, then the persistent configuration will also be updated;
these two commands can be given separately, or both together. If you
don't specify either (you can optionally specify "--current" for the
same effect), then the "current" config will be updated (i.e. if the
network is active, then only its live config is affected, but if the
network is inactive, only the persistent config is affected).
https://www.gnu.org/licenses/gpl-howto.html recommends that
the 'If not, see <url>.' phrase be a separate sentence.
* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/; If/. If/
tools/virsh-network.c:
* vshNetworkSorter to sort networks by name
* vshNetworkListFree to free the network objects list.
* vshNetworkListCollect to collect the network objects, trying
to use new API first, fall back to older APIs if it's not supported.
* New options --persistent, --transient, --autostart, --no-autostart,
for net-list, and new field 'Persistent' for its output.
tools/virsh.pod:
* Add documents for the new options.
Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.
vshConnectionUsability() no longer needs to be exported and this patch
marks it static.
Another relatively easy file split.

* tools/virsh.c: Use new header.

(vshCommandOptNetworkBy): Update signature.
In preparation for splitting virsh-interface.c, I found these
functions need to be declared in virsh.h, as well as one that
belongs more properly in virsh-domain.h. Also, since we
use the VSH_BY* flags in more than one function, I improved
how they are used.
* tools/virsh.h (vshNameSorter, vshCmdHasOption): Declare.
(VSH_BYID): Turn into enum.

* tools/virsh-domain.h): ...here.

Virsh uses an error handler to save errors from libvirt. On some code
paths it's needed to clear libvirt errors and continue on fallback code
paths without reporting failure.
This patch adds function vshResetLibvirtError() that clears error
returned by libvirt and updates all places where the old two-line method
was used.
Commands to manage network are moved from virsh.c to virsh-network.c,
with a few helpers for network command use.
* virsh.c: Remove network commands and a few helpers.
* virsh-network.c: New file, filled with network commands and its
helpers.
* po/POTFILES.in: Add virsh-network.c
* cfg.mk: Skip to check config.h including for virsh-network.c
