1199edb1d4 Introduce max_queued_clients
This configuration knob lets user to set the length of queue of
connection requests waiting to be accept()-ed by the daemon. IOW, it
just controls the @backlog passed to listen:

  int listen(int sockfd, int backlog);

ed3bac713c Setup default access control manager in libvirtd
Add a new 'access_drivers' config parameter to the libvirtd.conf
configuration file. This allows admins to setup the default
access control drivers to use for API authorization. The same
driver is to be used by all internal drivers & APIs

597fe3cee6 daemon: Create priority workers pool
This patch annotates APIs with low or high priority.
In low set MUST be all APIs which might eventually access monitor
(and thus block indefinitely). Other APIs may be marked as high
priority. However, some must be (e.g. domainDestroy).

For high priority calls (HPC), there are some high priority workers
(HPW) created in the pool. HPW can execute only HPC, although normal
worker can process any call regardless priority. Therefore, only those
APIs which are guaranteed to end in reasonable small amount of time
can be marked as HPC.

The size of this HPC pool is static, because HPC are expected to end
quickly, therefore jobs assigned to this pool will be served quickly.
It can be configured in libvirtd.conf via prio_workers variable.
Default is set to 5.

To mark API with low or high priority, append priority:{low|high} to
it's comment in src/remote/remote_protocol.x. This is similar to
autogen|skipgen. If not marked, the generator assumes low as default.

07f9b6f019 Allow certificate sanity checking to be disabled
When libvirtd starts it it will sanity check its own certs,
and before libvirt clients connect to a remote server they
will sanity check their own certs. This patch allows such
sanity checking to be skipped. There is no strong reason to
need to do this, other than to bypass possible libvirt bugs
in sanity checking, or for testing purposes.

libvirt.conf gains tls_no_sanity_certificate parameter to
go along with tls_no_verify_certificate. The remote driver
client URIs gain a no_sanity URI parameter

* daemon/test_libvirtd.aug, daemon/libvirtd.conf,
  daemon/libvirtd.c, daemon/libvirtd.aug: Add parameter to
  allow cert sanity checks to be skipped
* src/remote/remote_driver.c: Add no_sanity parameter to
  skip cert checks
* src/rpc/virnettlscontext.c, src/rpc/virnettlscontext.h:
  Add new parameter for skipping sanity checks independantly
  of skipping session cert validation checks

8f680ad3b8 Basic framework for auditing integration
Integrate with libaudit.so for auditing of important operations.
libvirtd gains a couple of config entries for auditing. By
default it will enable auditing, if its enabled on the host.
It can be configured to force exit if auditing is disabled
on the host. It will can also send audit messages via libvirt
internal logging API

Places requiring audit reporting can use the VIR_AUDIT
macro to report data. This is a no-op unless auditing is
enabled

* autobuild.sh, mingw32-libvirt.spec.in: Disable audit
  on mingw
* configure.ac: Add check for libaudit
* daemon/libvirtd.aug, daemon/libvirtd.conf,
  daemon/test_libvirtd.aug, daemon/libvirtd.c: Add config
  options to enable auditing
* include/libvirt/virterror.h, src/util/virterror.c: Add
  VIR_FROM_AUDIT source
* libvirt.spec.in: Enable audit
* src/util/virtaudit.h, src/util/virtaudit.c: Simple internal
  API for auditing messages
