The opening of files for FD passing for a chardev backend was historically done in the function which is formatting the commandline. This has multiple problems. Firstly the function takes a lot of parameters which need to be passed through the commandline formatters. This made the 'qemuBuildChrChardevStr' extremely unappealing to the extent that we have multiple other custom formatters in places which didn't really want to use the function. Additionally the function is also creating files in the host in certain configurations which is wrong for a commandline formatter to do. This meant that e.g. not all chardev test cases can be converted to use DO_TEST_CAPS_LATEST as we attempt to use such code path and attempt to create files outside of the test directory. This patch moves the opening of the filedescriptors from 'qemuBuildChrChardevFileStr' into a new helper 'qemuProcessPrepareHostBackendChardevOne' which is called using 'qemuDomainDeviceBackendChardevForeach'. To preserve test behaviour we also have another instance 'testPrepareHostBackendChardevOne' which is populating mock filedescriptors.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
