The label is used only for the error path, thus rename cleanup.

Reject the VM startup if the perf event structure can't be allocated.

Since the field is internal to libvirt we can allow the users to modify
it.

Both disk->src->shared and disk->src->readonly can't be modified when
changing disk source for floppy and cdrom drives since both arguments
are passed as arguments of the disk rather than the image in qemu.

Historically these fields have only two possible values since they are
represented as XML thus we need to ignore if user did not provide them
and thus we are treating them as false.

disk->dst represents the <target> element in the XML.

If qemu doesn't support DEVICE_TRAY_MOVED event the code that attempts
to change media would attempt to re-eject the tray even if it wouldn't
be notified when the tray opened. Add a capability bit and skip retrying
for old qemus.

Empty floppy drives start with tray in "open" state and libvirt did not
refresh it after startup. The code that inserts media into the tray then
waited until the tray was open before inserting the media and thus
floppies could not be inserted.

These are wrappers over virStreamRecv and virStreamSend so that
users have to care about nothing but writing data into / reading
data from a sink (typically a file). Note, that these wrappers
are used exclusively on client side as the daemon has slightly
different approach. Anyway, the wrappers allocate this buffer and
use it for intermediate data storage until the data is passed to
stream to send, or to the client application. So far, we are
using 64KB buffer. This is enough, but suboptimal because server
can send messages up to VIR_NET_MESSAGE_LEGACY_PAYLOAD_MAX bytes
big (262120B, roughly 256KB). So if we make the buffer this big,
a single message containing the data is sent instead of four,
which is current situation. This means lower overhead, because
each message contains a header which needs to be processed, each
message is processed roughly same amount of time regardless of
its size, less bytes need to be sent through the wire, and so on.
Note that since server will never sent us a stream message bigger
than VIR_NET_MESSAGE_LEGACY_PAYLOAD_MAX there's no point in
sizing up the client buffer past this threshold.

There are two functions on the client that handle incoming stream
data.  The first one virNetClientStreamQueuePacket() is a low
level function that just processes the incoming stream data from
the socket and stores it into an internal structure. This happens
in the client event loop therefore the shorter the callbacks are,
the better. The second function virNetClientStreamRecvPacket()
then handles copying data from internal structure into a client
provided buffer.
Change introduced in this commit makes just that: new queue for
incoming stream packets is introduced. Then instead of copying
data into intermediate internal buffer and then copying them into
user buffer, incoming stream messages are queue into the queue
and data is copied just once - in the upper layer function
virNetClientStreamRecvPacket(). In the end, there's just one
copying of data and therefore shorter event loop callback. This
should boost the performance which has proven to be the case in
my testing.

The man page says: "(Re)-Connect to the hypervisor. When the shell is
first started, this is automatically run with the URI parameter
requested by the "-c" option on the command line."  However, if you run:

  virsh -c 'test://default' 'connect; uri'

the output will not be 'test://default'.  That's because the 'connect'
command does not care about any virsh-only related settings and if it is
run without parameters, it connects with @uri == NULL.  Not only that
doesn't comply to what the man page describes, but it also doesn't make
sense.  It also means you aren't able to reconnect to whatever you are
connected currently.

So let's fix that in both virsh and virt-admin add a test case for it.

This reverts commit 6e244c65, which
added support to qemu for the "peer" attribute in domain interface <ip>
elements.

It's being removed temporarily for the release of libvirt 1.3.4
because the feature doesn't work, and there are concerns that it may
need to be modified in an externally visible manner which could create
backward compatibility problems.

 Conflicts:
   tests/qemuxml2argvmock.c - a mock of virNetDevSetOnline() was added
   which may be assumed by other tests added since the original commit,
   so it isn't being reverted.

FD passing APIs like CreateXMLWithFiles or OpenGraphicsFD will leak
file descriptors. The user passes in an fd, which is dup()'d in
virNetClientProgramCall. The new fd is what is transfered to the
server virNetClientIOWriteMessage.

Once all the fds have been written though, the parent msg->fds list
is immediately free'd, so the individual fds are never closed.

This closes each FD as its send to the server, so all fds have been
closed by the time msg->fds is free'd.

If we want to delete all disks for container or vm
we should make a loop from 0 to NumberOfDisks and always
use zero index in PrlVmCfg_GetHardDisk to get disk handle.
When we delete first disk after that numbers of other disks
will be changed, start from 0 to NumberOfDisks-1.
That's why we should always use zero index.

Add ULL suffix to all related operands of << or shift will give
all zeros instead of correct mask.

Similarly to what commit 71408079 did with some internal paths,
clear vnc socket paths that were generated by us.  Having such path in
the definition can cause trouble when restoring the domain.  The path is
generated to the per-domain directory that contains the domain ID.
However, that ID will be different upon restoration, so qemu won't be
able to create that socket because the directory will not be prepared.

To be able to migrate to older libvirt, skip formatting the socket path
in migratable XML if it was autogenerated.  And mark it as autogenerated
if it already exists and we're parsing live XML.

Best viewed with '-C'.

If the domain name is long enough, the timestamp can prolong the
filename for automatic coredump to more than the filesystem's limit.
Simply shorten it like we do in other places.  The timestamp helps with
the unification, but having the ID in the name won't hurt.

Currently we only allow /dev/random and /dev/hwrng as host input
for <rng><backend model='random'/> device. This was added after
various upstream discussions in commit 4932ef45

However this restriction has generated quite a few complaints over
the years, so a new discussion was initiated:

http://www.redhat.com/archives/libvir-list/2016-April/msg00987.html

Several people suggested removing the restriction, and nobody really
spoke up to defend it. So this patch drops the path restriction
entirely

If you compile a client --without-polkit, and connect to a URI that needs
polkit auth, the connection will fail with:

$ ./tools/virsh --connect qemu+ssh://crobinso@machine/system
error: failed to connect to the hypervisor
error: authentication failed: unsupported authentication type 2

This is because the client side portion of the polkit handling is
compiled out. However, nothing polkit specific is actually required
of the client.

Fix that error by unconditionally compiling the basic polkit client
handling.

Commit 1d440008 added some code that was not indented properly
and broke syntax-check. Fix it.

If libvirt-daemon-config-network is installed while libvirtd is already
running, the daemon doesn't notice the network. Users then have to
manually restart libvirtd (or reboot) to pick up the network.

Instead let's trigger a daemon restart when the package is first installed.
Then the default network is available immediately if libvirtd was already
running.

The hex range already tried to allow for it, but it wasn't using
the correct XML hex syntax. Fix it, and test it

Since commit 9b77ce63 we create a .in file while building all
man pages, including those in the tools/ directory; update the
ignore patterns to take this change into account.

The new ignore patterns are generic enough that we can get rid of
a few existing ones as well.

All top-level functions have been moved to this class.

On top of that, the app.warning() method has been defined,
so that calls to it - already present in rebuild() - can
actually succeed.

This method is used in eg. index.merge(), but is not defined
anywhere. The implementation has been copied from docBuilder.

Since commit d195cffa, both $(srcdir) and $(abs_builddir)
are passed to the apibuild.py script; however, since the
former is a relative path and the latter an absolute one, the
script might not be able to detect whether they point to the
same location.

Pass both as relative paths to avoid the issue.

Change 'ephemeral' to 'isephemeral' and 'private' to 'isprivate' since
both are bools.

Introduce the final accessor's to _virSecretObject data and move the
structure from virsecretobj.h to virsecretobj.c

The virSecretObjSetValue logic will handle setting both the secret
value and the value_size. Some slight adjustments to the error path
over what was in secretSetValue were made.

Additionally, a slight logic change in secretGetValue where we'll
check for the internalFlags and error out before checking for
and erroring out for a NULL secret->value. That way, it won't be
obvious to anyone that the secret value wasn't set rather they'll
just know they cannot get the secret value since it's private.
