This patch implement a set of interfaces for perf event. Based on
these interfaces, we can implement internal driver API for perf,
and get the results of perf conuter you care about.

These functions are going to be reused very shortly. So instead
of duplicating the code, lets move them into utils module.

The problem with the original virLogParseOutputs method was that the way it
parsed the input, walking the string char by char and using absolute jumps
depending on the virLogDestination type, was rather complicated to read.
This patch utilizes virStringSplit method twice, first time to filter out any
spaces and split the input to individual log outputs and then for each
individual output to tokenize it by to the parts according to our
PRIORITY:DESTINATION?(:DATA) format. Also, to STREQLEN for matching destination
was replaced with virDestinationTypeFromString call.

Since we have the opportunity now, let's save some precious code lines.

This API is merely a convenience API, i.e. when managing clients connected to
daemon's servers, we should know (convenience) which server the specific client
is connected to. This implies a client-side representation of a server along
with a basic API to let the administrating client know what servers are actually
available on the daemon.

This change is merely because admin_server would contain all the code
from dispatchers and helpers to the actual APIs. Admin should have
similar structure to the daemon-side remote driver - dispatchers and
helpers in a separate module, APIs in a separate module.

Best viewed with -M.

Create a new module qemu_alias.c to handle the qemuAssign*Alias* APIs
and the qemuDomainDeviceAliasIndex

Create new modules qemu_domain_address.c and qemu_domain_address.h to
contain all the new functions and header data. Additionally move any
supporting static functions.

Make qemuDomainSupportsPCI non static.

Also, move and rename the following:

qemuSetSCSIControllerModel to qemuDomainSetSCSIControllerModel
qemuCollectPCIAddress to qemuDomainCollectPCIAddress
qemuValidateDevicePCISlotsPIIX3 to qemuDomainValidateDevicePCISlotsPIIX3
qemuAssignDevicePCISlots to qemuDomainAssignDevicePCISlots

Move the misplaced function from qemu_command.c to qemu_interface.c

Extract out the qemuParseCommandLine{String|Pid} into their own
separate module - taking with it all the various static functions.

Causes a ripple effect with a few other modules to include the
new qemu_parse_command.h.

Narrowed down the list of #include's in the split out module to
those that are necessary for build.

Our domain_conf.* files are big enough. Not only they contain XML
parsing code, but they served as a storage of all functions whose
name is virDomain prefixed. This is just wrong as it gathers not
related functions (and modules) into one big file which is then
harder to maintain. Split virDomainObjList module into a separate
file called virdomainobjlist.[ch].

Introduce a new API to get libvirt version. It is worth noting, that
libvirt-admin and libvirt share the same version number. Unfortunately,
our existing API isn't generic enough to be used with virAdmConnectPtr
as well. Also this patch wires up this API to the virt-admin client
as a generic cmdVersion command.

This patch introduces virt-admin client which is based on virsh client,
but had to reimplement several methods to meet virt-admin specific needs
or remove unnecessary virsh specific logic.

Add the virLogManager API which allows for communication with
the virtlogd daemon to RPC program. This provides the client
side API to open log files for guest domains.

The virtlogd daemon is setup to auto-spawn on first use when
running unprivileged. For privileged usage, systemd socket
activation is used instead.

Define a new RPC protocol for the virtlogd daemon that provides
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.

Copy the virtlockd codebase across to form the initial virlogd
code. Simple search & replace of s/lock/log/ and gut the remote
protocol & dispatcher. This gives us a daemon that starts up
and listens for connections, but does nothing with them.

Add virRotatingFileReader and virRotatingFileWriter objects
which allow reading & writing from/to files with automation
rotation to N backup files when a size limit is reached. This
is useful for guest logging when a guaranteed finite size
limit is required. Use of external tools like logrotate is
inadequate since it leaves the possibility for guest to DOS
the host in between invokations of logrotate.

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.

This patch adds feature for lxc containers to inherit namespaces.
This is very similar to what lxc-tools or docker provides.  Look
for "man lxc-start" and you will find that you can pass command
args as [ --share-[net|ipc|uts] name|pid ]. Or check out docker
networking option in which you can give --net=container:NAME_or_ID
as an option for sharing +namespace.

>From this patch you can add extra libvirt option to share
namespace in following way.

 <lxc:namespace>
   <lxc:sharenet type='netns' value='red'/>
   <lxc:shareipc type='pid' value='12345'/>
   <lxc:shareuts type='name' value='container1'/>
 </lxc:namespace>

The netns option is specific to sharenet. It can be used to
inherit from existing network namespace.

In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.

Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.

Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.

The driver only supports VIR_ARCH_PPC64 and VIR_ARCH_PPC64LE.

Just shuffling files around and updating the build system
accordingly. No functional changes.

This reverts commit 5792fabb.

I mistakenly pushed it along with the Admin API series.

Just one of the simplest functions that returns string "Clients: X"
where X is the number of connected clients to daemon's first
subserver (the original one), so it can be tested using virsh, ipython,
etc.

The subserver is gathered by incrementing its reference
counter (similarly to getting qemu capabilities), so there is no
deadlock with admin subserver in this API.

Here you can see how functions should be named in the client (virAdm*)
and server (adm*).

There is also a parameter @flags that must be 0, which helps testing
proper error propagation into the client.

Initial scratch of the admin library.  It has its own virAdmConnectPtr
that inherits from virAbstractConnectPtr and thus trivially supports
error reporting.

There's pkg-config file added and spec-file adjusted as well.

Since the library should be "minimalistic" and not depend on any other
library, the list of files is especially crafted for it.  Most of them
could've been put to it's own sub-libraries that would be LIBADD'd to
libvirt_util, libvirt_net_rpc and libvirt_setuid_rpc_client to minimize
the number of object files being built, but that's a refactoring that
isn't the orginal aim of this commit.
