5792fabb7b admin: Add virAdmHello function
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.

55e0c840af Add libvirt-admin library
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.

29230951f1 storage: Generate correct parameters for CIFS
https://bugzilla.redhat.com/show_bug.cgi?id=1186969

When generating the path to the dir for a CIFS/Samba driver, the code
would generate a source path for the mount using "%s:%s" while the
mount.cifs expects to see "//%s/%s". So check for the cifsfs and
format the source path appropriately.

Additionally, since there is no means to authenticate, the mount
needs a "-o guest" on the command line in order to anonymously mount
the Samba directory.

38c9494878 storage: Fix the schema and add tests for cifs pool
Commit id '887dd362' added support for a netfs pool format type 'cifs'
and 'gluster' in order to add rng support for Samba and glusterfs netfs
pools. Originally, the CIFS type support was added as part of commit
id '61fb6979'. Eventually commit id 'b325be12' fixed the gluster rng
definition to match expectations.

As it turns out the CIFS rng needed a similar change since the directory
path is not an absDirPath, rather just a dirPath will be required.

1feaccf000 storage: Need to set secrettype for direct iscsi disk volume
https://bugzilla.redhat.com/show_bug.cgi?id=1200206

Commit id '1b4eaa61' added the ability to have a mode='direct' for
an iscsi disk volume.  It relied on virStorageTranslateDiskSourcePool
in order to copy any disk source pool authentication information to
the direct disk volume, but it neglected to also copy the 'secrettype'
field which ends up being used in the domain volume formatting code.
Adding a secrettype for this case will allow for proper formatting later
and allow disk snapshotting to work properly

Additionally libvirtd restart processing would fail to find the domain
since the translation processing code is run after domain xml processing,
so handle the the case where the authdef could have an empty secrettype
field when processing the auth and additionally ignore performing the
actual and expected auth secret type checks for a DISK_VOLUME since that
data will be reassembled later during translation processing of the
running domain.

f886701290 virCapabilitiesDomainDataLookup: Produce saner error message
During a review, I've noticed this error message that was eventually
produced when I was trying to define a domain:

error: invalid argument: could not find capabilities for arch=mips64el
domaintype=(null)

Look at the (null). Why is it there? Well, during XML parsing, we try
to look up the default emulator for given OS type and possibly virt
type too. And this is the problem, because if we don't want to look up
by virt type, a -1 is passed to note this fact. Later, the code
handles -1 just right. Except for error message. When it is
constructed (in a very fabulous way I must say), the value is compared
to zero, not -1. And since we don't have any translation from -1 to a
virt type string, we just print (null).
