ASan needs to be loaded first before gstreamer is loaded. This was not
possible, so verify_asan_link_order was disabled. Better way to tackle
this issue was disabling forks on the gstreamer side.
verify_asan_link_order=0 disables the check on ASan side which checks if
ASan was loaded before any other shared objects. Since, gstreamer spawns
a child helper process while building the registry, we needed to disable
this check. But with gst_registry_fork_set_enabled() it is possible to
disable spawning this child helper process, so this ensures that ASan is
loaded before any other shared object is loaded.

This patch simplifies memory management, i.e., by replacing bare
pointers with g_autoptr or g_autofree according to use case.
While at it also update time representation of timeout variable with
GST_SECOND.

This patch adds a test to test if single stream using libcamera's
gstreamer element works.
We need to work around two distinct issues with ASan when enabled in the
build:
- glib has a known leak at initialization time. This is covered by the
suppression file shipped with glib, but it's not clear how to use it
automatically. For now, disable leak detection to avoid test failures.
- GStreamer spawns a child process to scan plugins. If GStreamer is
compiled without ASan (which is likely) but libcamera is, dlopen()ing
the libcamera plugin will cause an ASan link order verification
failure. Disable the verification child processes to work around the
problem. This requires gcc 8 or newer.
