0c9862d6e3 gstreamer: allocator: Ensure camera manager stay alive
Without the camera manager, it is not possible to cleanly delete the
FrameBufferAllocator object. Keep the camera manager alive until all the
memory object have been released.

A shared_ptr to the CameraManager is introduced which is itself stored
as a plain pointer and allocated and released explicitly. When more
than one C++ member is required, this can be refactored to use a new C++
class, but the struct _GstLibcameraAllocator is allocated and freed by
glib, so it does not have automatic destruction presently.

6fc5f90f16 test: gstreamer: Include missing sanitizer/asan_interface.h header
The GStreamer tests define a __asan_default_options() function to
influence the behaviour of ASan. The function is declared in
sanitizer/asan_interface.h, but we don't include the header. This will
cause missing declaration warnings when we enable the
-Wmissing-declarations option.

Include the header to fix the issue. It can't be done unconditionally as
not all toolchains provide ASan, so check for its availability at
configuration time.

a2a61121eb test: gstreamer: Simplify single stream test
The single stream test for the GStreamer component has a simple pipeline
construction using only a fakesink.

The implementation currently supports connecting to a more complex
stream construction defined by the streamDescription, but this is over
engineered for the simple need to start a stream to capture and discard
the frames.

Convert the use of gst_parse_bin_from_description_full() which uses only
a single element 'fakesink' to construct the fakesink directly and link
it to the libcamerasrc.

3cb20bc230 libcamera: Drop remaining file name from header comment blocks
Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.

Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment blocks in all
remaining locations that were not caught by the automated script as they
are out of sync with the file name.

Readers of the source code are expected to know which file they're

The change was generated with the following script:

----------------------------------------

dirs="include/libcamera src test utils"

declare -rA patterns=(
	['c']=' \* '
	['cpp']=' \* '
	['h']=' \* '
	['py']='# '
	['sh']='# '
)

for ext in ${!patterns[@]} ; do
	files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
	pattern=${patterns[${ext}]}

	for file in $files ; do
		name=$(basename ${file})
		sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
	done
done
----------------------------------------

This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

17d8b89deb test: gstreamer: Remove videoconvert element from pipeline
The GStreamer single stream test uses the following pipeline:

	libcamerasrc ! videoconvert ! fakesink

The videoconvert element isn't useful as the data is thrown away by the
fakesink anyway. We can shorten the pipeline to

	libcamerasrc ! fakesink

to save CPU time and to avoid depending on the gstreamer1.0-plugins-base
package to run the unit tests.

The test could be further simplified by replacing
gst_parse_bin_from_description_full() with gst_element_factory_make(),
now that we only add one element to the bin. The extra cost incurred by
the bin only impacts initialization time, and using a bin will make it
easier to add other elements in the future if needed. Keep the bin, and
only drop the videoconvert element.

03526e58d1 tests: gstreamer: Fix compiler error with gcc 8.4.0
The provider g_autoptr variable introduced by commit adb1bbb748
("tests: gstreamer: Test cameras' enumeration from GstDeviceProvider")
is left uninitialized when declared. The cleanup function could thus get
called on an unitialized variable if the scope was exited before the
variable gets initialized. This can't occur here, but gcc 8.4.0 still
complains about it:

/usr/include/glib-2.0/glib/gmacros.h: In member function ‘virtual int GstreamerDeviceProviderTest::run()’:
/usr/include/glib-2.0/glib/gmacros.h:1049:27: error: ‘provider’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
     { if (_ptr) (cleanup) ((ParentName *) _ptr); }                                                              \

../test/gstreamer/gstreamer_device_provider_test.cpp:37:32: note: ‘provider’ was declared here
   g_autoptr(GstDeviceProvider) provider;

Silence the error by initializing the variable to NULL at declaration
time. This is a good practice in any case, as later refactoring could
otherwise introduce a scope exit before initialization.

46340ced12 test: gstreamer: Fix failure of gstreamer_multistream_test
Multistream test failed with the following logs, to run on Raspberry Pi 4 due
to a bug introduced in one of the recent patches refactoring the code
that fails to set the camera-name property with a valid camera id
string.

WARN libcamerasrc gstlibcamerasrc.cpp:347:gst_libcamera_src_open:<libcamera> error: Could not find a camera named ''.
WARN libcamerasrc gstlibcamerasrc.cpp:347:gst_libcamera_src_open:<libcamera> error: libcamera::CameraMananger::get() returned nullptr

This patch assigns the camera->id() to the variable cameraName_ that is
later used to set element property "camera-name" needed to call the
specific camera which supports multistreams. Move the code to set
element property "camera-name" to base class GstreamerTest.

5646849b59 test: gstreamer: Check availability of cameras before running
Move the logic for checking the availability of cameras from
multi_stream_test to gstreamer test base class. Since
single_stream_class always assumes that a camera is available on the
system (which is not always the case for e.g. RPi in CI/CD environments)
it makes sense to have the availability check in the base class.
If no cameras are available, the behaviour should be to skip instead
of a failure.

We currently have 2 tests for gstreamer differing based on number
of streams supported by the camera. Hence, the camera availability
is checked in conjunction with the number of the streams required by
the derived class.

c7daf645d4 test: gstreamer: Simplify elements' ownerships
In gstreamer, when elements are created, usually a floating [1]
reference is returned which simply means, there is no ownership
transfer (yet). Once can simply check for NULL and return through
an error path, without bothering to clean up. Hence, g_autoptr is
not much of help here.

If the NULL checks have been passed successfully, elements are ready
to use. However, we must claim ownership/reference it before using
them via g_object_ref_sink().

This patch build upon this principle and removes the g_autoptr
from gstreamer test base class (gstreamer_test.cpp) whereever
necessary to tide up the code.

af1f731f47 test: gstreamer: Disable gstreamer registry forks
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.

25462474f8 test: gstreamer: Add test for gstreamer single stream
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.
