Check if the vm is alive before using hotpatch api by calling
virDomainObjCheckActive() to check vm id and calling
qemuDomainHotpatchCheckPid() to check vm pid.

GLibC has a really complicated way of dealing with the 'stat' function
historically, which means our mocks in turn have to look at four
different possible functions to replace, stat, stat64, __xstat,
__xstat64.
In Fedora 33 and earlier:
- libvirt.so links to __xstat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat and __xstat
In Fedora 34 rawhide:
- libvirt.so links to stat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat
Historically we only looked at the exported symbols from libc.so to
decide which to mock.
In F34 though we must not consider __xstat / __xstat64 though because
they only existance for binary compatibility. Newly built binaries
won't reference them.
Thus we must introduce a header file check into our logic for deciding
which symbol to mock. We must ignore the __xstat / __xstat64 symbols
if they don't appear in the sys/stat.h header, even if they appear
in libc.so

Currently the default values of retry_interval and retry_timeout are set
to -1, when 'driver' option exists without retry fileds. It conflicts
with the default values when the 'driver' option does not exist.
So let's set default values of retry_interval and retry_timeout to 0 when
retry policy is not enabled.

Introduce error_policy=/rerror_policy='retry' to support
werror=/rerror=retry mechanism in qemu.
Add retry_interval parameter to control the interval between retries.
Add retry_timeout parameter to control the total retry times.
