changes from previous version 4 [1]:
- patch 1:
* moved 'dev' inside the for loop in qemuProcessHandleBlockThreshold()
* moved 'id' inside the 'for' loop in qemuProcessLookupPTYs()
* moved 'path' inside both conditionals in qemuProcessBuildDestroyMemoryPaths()
* set 'template=NULL' in case g_mkdtemp() succeeds in qemuProcessQMPInit()
- patch 2: new patch. add g_autoptr() support for
qemuDomainLogContextPtr
- patch 3:
* using g_autoptr() on feasible virCommandPtr and
* qemuDomainLogContextPtr

The 'error:' label here tipped me that something might be off. 'models'
is only supposed to be freed on error, but this frees it
unconditionally. I adapted this function to use g_steal_pointer as well,
and pushed this series with that addition
Thanks,

New subject: [libvirt] [PATCH v5 4/5] qemu_process.c: remove cleanup labels after g_auto*() changes
The g_auto*() changes made by the previous patches made a lot
of 'cleanup' labels obsolete. Let's remove them.

New subject: [libvirt] [PATCH v5 5/5] qemu_process.c: remove 'cleanup' label from qemuProcessCreatePretendCmd()
The 'cleanup' flag is doing no cleaup in this function. We can
remove it and return NULL on error or qemuBuildCommandLine().
