Paolo Bonzini 9f45a64109 trace: fix "-trace file=..." ... Because trace_opt_parse always deletes the options it has parsed, trace_init_file's call to qemu_find_opts_singleton always creates an empty -trace option group. Therefore, the subsequent qemu_opt_get(opts, "file") always returns NULL. To fix this, save the last "-trace file=..." option in a global variable and use it later in trace_init_file. This is similar to what was done before commit 92eecfff32 ("trace: remove argument from trace_init_file", 2020-11-11), except contained within trace/control.c and without memory leaks.
