If for some reason there is an existing log file, that is larger then
max length of log file, we need to rollover that file immediately.
Trying to figure out how much data we could write will resolve in
overflow of unsigned variable 'towrite' and this leads to segfault.

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.

As we need a client disconnect handler, we also need a mechanism to register
such handlers for a client. This patch introduced both the close callbacks and
also the client vshAdmCatchDisconnect handler to be registered with it. By
registering the handler we still need to make sure the client can react to
daemon's events like disconnect or keepalive, so asynchronous I/O event polling
is necessary to be enabled too.

Now that we introduced URI support in libvirt-admin, we should also support URI
aliases during connection establishment phase. After applying this patch,
virAdmConnectOpen will also support VIR_CONNECT_NO_ALIASES flag.

As we need to provide support for URI aliases in libvirt-admin as well, URI
alias matching needs to be internally visible. Since
virConnectOpenResolveURIAlias does have a compatible signature, it could be
easily reused by libvirt-admin. This patch moves URI alias matching to util,
renaming it accordingly.

Since virt-admin should be able to connect to various admin servers
on hosted different daemons, we need to provide URI support to
libvirt-admin.

As we plan to add more and more logic to remote connecting methods,
these cannot be generated from admin_protocol.x anymore. Instead,
this patch implements these to methods explicitly.

By moving the remote version into a separate module, we gain a slightly
better maintainability in the long run than just by leaving it in one
place with the existing libvirt-admin library which can start getting
pretty messy later on.

Since most of our APIs rely on an acive functional connection to a daemon and
we have such a mechanism in libvirt already, there's need to have such a way in
libvirt-admin as well. By introducing a new public API, this patch provides
support to check for an active connection.

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.

Unfortunately, client side version retrieval API virGetVersion uses
one-time initialization (due to the fact we might not have initialized the
library by calling connect prior to this) which is not completely compatible
with admin initialization. This API is rather simplistic and reimplementing
it for admin might be the preferred method of reusing it. Note that even though
the method will be reimplemented, the version number is still the same for both
the libvirt and libvirt-admin library.

virConnectGetConfig and virConnectGetConfigPath were static libvirt
methods, merely because there hasn't been any need for having them
internally exported yet. Since libvirt-admin also needs to reference
its config file, 'xGetConfig' should be exported.
Besides moving, this patch also renames the methods accordingly,
as they are libvirt config specific.

Since libvirt-admin is a separate library, it should also have a separate
config file. Available settings are currently the same as for libvirt.conf.

As it turned out, we need to share some enums and declarations between
libvirt.h and libvirt-admin.h, but since our policy forbids direct includes of
libvirt*.h, there has to be some header exempt from this rule. This patch moves
the relevant part of code from libvirt.h.in to libvirt-common.h.in. Moreover,
since there is no need to have libvirt.h generated anymore, introduce a new
header libvirt.h which was previosly ignored from git and make the common
header ignored and generated instead.

qemu 2.5 provides virtio video device.  It can be used with -device
virtio-vga for primary devices, or -device virtio-gpu for non-vga
devices. However, only the primary device (VGA) is supported with this
patch.

The virtlogd daemon is launched with a 30 second timeout for
unprivileged users. Unfortunately the timeout is only inhibited
while RPC clients are connected, and they only connect for a
short while to open the log file descriptor. We need to hold
an inhibition for as long as the log file descriptor itself
is open.

Currently the QEMU stdout/stderr streams are written directly to
a regular file (eg /var/log/libvirt/qemu/$GUEST.log). While those
can be rotated by logrotate (using copytruncate option) this is
not very efficient. It also leaves open a window of opportunity
for a compromised/broken QEMU to DOS the host filesystem by
writing lots of text to stdout/stderr.

This makes it possible to connect the stdout/stderr file handles
to a pipe that is provided by virtlogd. The virtlogd daemon will
read from this pipe and write data to the log file, performing
file rotation whenever a pre-determined size limit is reached.

Currently the QEMU monitor is given an FD to the logfile. This
won't work in the future with virtlogd, so it needs to use the
qemuDomainLogContextPtr instead, but it shouldn't directly
access that object either. So define a callback that the
monitor can use for reporting errors from the log file.
