This removes the opencoded payload freeing in the client, to use
the shared virNetMessageClearPayload call. Two changes:
- ClearPayload sets nfds=0, which fixes a potential crash if
an error path called virNetMessageFree/Clear on the message
after fds was free'd
- We drop the inner loop VIR_FORCE_CLOSE... this may mean fds are
kept open a little bit longer if the call is blocking but in
practice I don't think it will have any effect
I've noticed this while trying to compile libvirt on my arm box.

Problem is, @timestap is defined as time_t which is 32 bits long,
and we are typecasting it to long long which is 64bits long.
Solution is to make @timestamp type of long long. At the same
time, we can make @conn_time in _virNetServerClient struct long
long too. There is no need for it to be type of time_t.

In this function, @id is defined as unsigned long long. When
passing this variable to virJSONValueObjectGetNumberUlong(),
well address of this variable, it's typecasted to ull*. There
is no need for that. It's a same story with @nrequests_max.

Currently all qemu driver tests are statically linked to qemu driver
library, which makes it impossible to mock any API from the library.
This patch creates a shared qemu driver library which can be used
instead of the static one.
NB we can't use libvirt_driver_qemu.so directly since it is linked with
-module and it is supposed to be dlopened.

Bhyve supports ACPI shutdown by issuing SIGTERM signal to a bhyve
process.
Add the bhyveDomainShutdown() function and virBhyveProcessShutdown()
helper function that just sends SIGTERM to VM's bhyve process. If
a guest supports ACPI shutdown then process will be terminated and
this event will be noticed by the bhyve monitor code that will handle
setting proper status and clean up VM's resources by calling
virBhyveProcessStop().
Current implementation of domainDestroy for bhyve calls
virProcessKillPainfully() for the bhyve process and then
executes "bhyvectl --destroy".
This is wrong for two reasons:
* bhyvectl --destroy alone is sufficient because it terminates
the process
* virProcessKillPainfully() first sends SIGTERM and after few
attempts sends SIGKILL. As SIGTERM triggers ACPI shutdown that
we're not interested in, it creates an unwanted side effect in
domainDestroy.
Also, destroy monitor only after "bhyvectl --destroy" command succeeded
to avoid a case when the command fails and domain remains running, but
not being monitored anymore.
We can't guarantee which 64-bit type will be used in an RPC struct;
while %lu worked on 64-bit Linux, that won't always be the type
used on all 64-bit platforms; and certainly is not right for 32-bit:

Since nparams can be technically negative, it is a good practice throughout
our code to check if nparams actually has a non-negative value. The same effect
would be achieved by converting our internal typed params serializer argument
to 'unsigned' type, but it definitely would not be the path of least resistance.

Now that we have all the pieces in place, we can add the 'iothread=#' to
the command line for the (two) controllers that support it (virtio-scsi-pci
and virtio-scsi-ccw). Add the tests as well...
Rather than an if statement, use a switch.
The switch will also catch the illegal usage of 'iothread' with some other
kind of unsupported bus configuration.
Add the ability to add an 'iothread' to the controller which will be how
virtio-scsi-pci and virtio-scsi-ccw iothreads have been implemented in qemu.
Describe the new functionality and add tests to parse/validate that the
new attribute can be added.
Previous commit moved some lists out of the -devel package

Author: Cole Robinson <crobinso@redhat.com>

spec: Only pull in API docs with -devel package
What was not realized is that the rule 'libvirt-docs/*'
and ' docs/*.html docs/html docs/*.gif' actually point
to the exact same content. ie, we had previously included
the website HTML in *both* the -docs and -devel packages.
So this change ended up listing the files twice, which
caused RPM to print a load of warnings:

An iothread for virtio-scsi is a property of the controller. Add a lookup
of the 'virtio-scsi-pci' and 'virtio-scsi-ccw' device properties and parse
the output. For both, support for the iothread was added in qemu 2.4
while support for virtio-scsi in general was added in qemu 1.4.
Modify the various mock capabilities replies (by hand) to reflect the
when virtio-scsi was supported and then specifically when the iothread
property was added. For versions prior to 1.4, use the no device error
return for virtio-scsi. For versions 1.4 to before 2.4, add some data
for virtio-scsi-pci even though it isn't complete we're not looking for
anything specific there anyway. For 2.4 to 2.6, add a more complete reply.

We don't need them any longer; moreover, the previous structure
made it very easy for bugs to slip in, by having the result of one
check influence the following one.
By placing the check for "$with_init_script" = check front and
center, hopefully this won't happen (as easily) again.
Expose a public API to retrieve some identity and connection information about
a client connected to the specified server on daemon. The identity info
retrieved is mostly connection transport dependent, i.e. there won't be any
socket address returned for a local (UNIX socket) connection, while on the
other hand, when connected through TLS or unencrypted TCP, obviously no UNIX
process identification will be present in the returned data. All supported
values that can be returned in typed params are exposed and documented in
include/libvirt/libvirt-admin.h

We do have a similar method, serving the same purpose, for TLS, but we lack
one for SASL. So introduce one, in order for other modules to be able to find
out, if a SASL session is active, or better said, that a SASL session exists
at all.

Our socket address format is in a rather non-standard format and that is
because sasl library requires the IP address and service to be delimited by a
semicolon. The string form is a completely internal matter, however once the
admin interfaces to retrieve client identity information are merged, we should
return the socket address string in a common format, e.g. format defined by
URI rfc-3986, i.e. the IP address and service are delimited by a colon and
in case of an IPv6 address, square brackets are added:
Examples:
127.0.0.1:1234
[::1]:1234
This patch changes our default format to the one described above, while adding
separate methods to request the non-standard SASL format using semicolon as a
delimiter.

This patch could easily be squashed with the virAdmClientGetInfo method
introduced later one, but the idea was to split the logic to as many preferably
independent patches as possible. As the subject hints, this patch defines
some public typed params-related macros used within virAdmClientGetInfo
method. The thing is, there's one identity attribute missing in the set --
SELinux context, which libvirt internally supports in virIdentity, but it
doesn't seem to do much (or anything at all), so there's some room to extend
the set in the future.

Just like with server-related APIs, before any of client-based APIs can be
called, a reference to a client-side client object needs to be obtained. For
this purpose, a lookup method should exist. Apart from the client retrieval
logic, a new error code for non-existent client had to be added as well.
