fda5a98e9e driver config: Introduce virFirmware object
The virQEMUDriverConfig object contains lists of
loader:nvram pairs to advertise firmwares supported by
by the driver, and qemu_conf.c contains code to populate
the lists, all of which is useful for other drivers too.

To avoid code duplication, introduce a virFirmware object
to encapsulate firmware details and switch the qemu driver
to use it.

d8a8af3492 tls: remove support for gnutls 1.x.x, require 2.2.0
We need to use the gnutls_priority_set_direct method which
was not introduced until 2.1.7, so bump version to 2.2.0
which is the first stable release with it included. This
release dates from Dec 2007 so it is reasonable to ditch
support for the 1.x.x series for gnutls releases entirely.

c0bc172383 systemd: directly notify systemd instead of using sd_notify
The sd_notify method is used to tell systemd when libvirtd
has finished starting up. All it does is send a datagram
containing the string parameter to systemd on a UNIX socket
named in the NOTIFY_SOCKET environment variable. Rather than
pulling in the systemd libraries for this, just code the
notification directly in libvirt as this is a stable ABI
from systemd's POV which explicitly allows independant
implementations:

"$NOTIFY_SOCKET Daemon Notifications" row:

4652b158aa secret: Create virsecretobj.c and virsecretconf.h
Move virSecretObj from secret_driver.c to virsecretobj.h

To support being able to create a hashed secrets list, move the
virSecretObj to virsecretobj.h so that the code can at least find
the definition.

This should be a temporary situation while the virsecretobj.c code
is patched in order to support a hashed secret object while still
having the linked list support in secret_driver.c. Eventually, the
goal is to move the virSecretObj into virsecretobj.c, although it
is notable that the existing model from which virSecretObj was
derived has virDomainObj in src/conf/domain_conf.h and virNetworkObj
in src/conf/network_conf.h, so virSecretObj wouldn't be unique if
it were to remain in virsecretobj.h  Still adding accessors to fetch
and store hashed object data will be the end goal.

Add definitions and infrastucture in virsecretobj.c to create and
handle a hashed virSecretObj and virSecretObjList including the class,
object, lock setup, and disposal API's. Nothing will call these yet.

This infrastructure will replace the forward linked list logic
within the secret_driver, eventually.

36785c7e77 device: cleanup input device code
The current code was a little bit odd.  At first we've removed all
possible implicit input devices from domain definition to add them later
back if there was any graphics device defined while parsing XML
description.  That's not all, while formating domain definition to XML
description we at first ignore any input devices with bus different to
USB and VIRTIO and few lines later we add implicit input devices to XML.

This seems to me as a lot of code for nothing.  This patch may look
to be more complicated than original approach, but this is a preferred
way to modify/add driver specific stuff only in those drivers and not
deal with them in common parsing/formating functions.

The update is to add those implicit input devices into config XML to
follow the real HW configuration visible by guest OS.

There was also inconsistence between our behavior and QEMU's in the way,
that in QEMU there is no way how to disable those implicit input devices
for x86 architecture and they are available always, even without graphics
device.  This applies also to XEN hypervisor.  VZ driver already does its
part by putting correct implicit devices into live XML.

That happens because without any specific options gcc doesn't keep enum
information in the resulting binary object.  I managed to isolate the
parameters of gcc that caused this issue to disappear, however I
remember that they influenced the resulting binaries quite a bit and
were definitely not something we would want to add as mandatory to the
build process.

So to deal with this cleanly, let's take that enum and separate it out
to its own header file.  Since it is only used in the lockd driver and
the protocol, lock_driver_lockd.h feels like a suitable name.

97c9ddefa1 build: Create needed folders without dependency tracking
The parameter --disable-dependency-tracking is supposed to speed up
one-time build due to the fact that it disables some dependency
extractors that, apparently, take longer time to execute.  That is a
problem for code that is generated into builddir (especially some
specific subdirectory) because the directory it should be installed to
does not exists in VPATH and without the dependency tracking is not
created.  Generating such file hence fails with -ENOENT.  In order to
keep generating files into builddir instead of srcdir, we must create
the directory ourselves.  This should finally fix the problem that is
being fixed multiple times since its introduction in commit a9fe620372
and let us continue with cleaning those parts of Makefiles that depend
on generating files into the srcdir rather than builddir as it should
be.

for handling of logs. The initial RPC method defined allows a
client to obtain a file handle to use for writing to a log
file for a guest domain. The file handle passed back will not
actually refer to the log file, but rather an anonymous pipe.
The virtlogd daemon will forward I/O between them, ensuring
file rotation happens when required.

Initially the log setup is hardcoded to cap log files at
128 KB, and keep 3 backups when rolling over, which gives
a max usage of 512 KB per guest.

bd6ae7b8ab vz: remove storage driver as never used
In fact, it was never used as far as vz has no features supporting it.
That is why there will be no harm to anyone if we just remove this code to
prevent further misunderstanding and efforts to support dead code.

439f29e78c vz: remove network driver as never used
At the time this code was added we had intentions to support libvirt interface
to manage vz networks. In fact, it was never implemented completely to work
correctly that makes me think that there will be no harm to anyone if we just
rip it off. Moreover, in vz7 we started to use libvirt bridge network driver to
manage networks.
