Add support for 2 new envvars for internal lvm2 test suite (though it could be possible usable for other cases) LVM_LOG_FILE_EPOCH Whether to add 'epoch' extension that consist from the envvar 'string' + pid + starttime in kernel units obtained from /proc/self/stat. LVM_LOG_FILE_UNLINK_STATUS Whether to unlink the log depending on return status value, so if the command is successful the log is automatically deleted. API is still for now experimental to catch various issue.
