We currently create stub 'setcon', 'setcon_raw' and 'security_disable'
APIs in the securityselinuxhelper.c mock, which set env variables to
control how other mock'd libselinux APIs respond. These stubs merely
set some env variables, and we have no need to call these stubs from
the library code, only test code.
The 'security_disable' API is now deprecated in libselinux, so we
stubbing it generates compiler warnings. Rather than workaround that,
just stop stubbing these APIs and set the required env variables
directly. With this change, we now only mock API calls we actually
use from the library code.

Introduce capabilities based on qemu commit 'v9.1.0-803-g05adb38839'.
Notable changes:
- new 9.2 machine types
- 'gluster' disk backend deprecated
- 'reconnect' option of chardevs replaced by 'reconnect-ms'
- this includes test output changes happening in this patch
as 'reconnect' was deprecated in the same patch that
introduced 'reconnect-ms' and thus couldn't be changed
incrementally
- cpu flags:
- 'ibpb-brtype' added
- 'vmx-exit-secondary-ctls' added
- 'vmx-entry-load-rtit-ctl' added
- migration capabilities/parameters
- 'zero-blocks' deprecated
- 'multifd-qatzip-level' added
- 'pty' chardev backend gained 'path' attribute
- 'cris' and 'she4b' arches removed (from 'query-cpus-fast' data)
- 'copy-before-write' block filter gained 'min-cluster-size'
- 'vhost-user-scmi', 'serial-mm' removed

Currently, an array of libxl_string_list (char **) or in other words,

and stored in serial_list, which is NULL at this point. There is an attempt to
reference an element of this serial_list when making a call to

QEMU uses Linux extensions to madvise() to include/exclude guest
memory from core dump. These are obviously not available
everywhere. Currently, users have two options:
1) configure <memory dumpCore=''/> in domain XML, or
2) configure dump_guest_core in qemu.conf
While these work, they may harm user experience as "things just
don't work" out of the box. Provide sane default in
virQEMUDriverConfigNew() so neither of two options is required.
To have predictable results in tests, explicitly set
cfg->dumpGuestCore to false in qemuTestDriverInit() (which
creates cfg object for tests).

This patch modifies the monitor code to take virJSONValue 'props'
instead of the chardev definition and adds the conversion from the
chardev definition to JSON on higher levels.
The monitor code now also attempts to extract the returned 'pty' if

the path is needed and missing.
