To iterate over an array of `T`, the iterator must be `(const) T *`,
so that the types are compatible when `T[]` decays into `T *`.
In the example when `struct foo *[]` decays, it becomes `struct foo **`,
which is not compatible with the the type of iterator, `struct foo *`.
Fix that by changing the type of the array to `struct foo[]`.
If the caller asks for MemFd, pass a DmaBuf because it is mostly
the same for v4l2.
Not very correct but it's not yet trivial to fall back to memfd.
And this way we have something to give to the clients that will work
when the client asks for MemFd or MemPtr.
It is more like how JACK2 does things.
We get FIFO scheduling by default and we don't get killed by RTKit
when doing long operations, which seem to be the case for many
plugins.
The thread name can only be 16 chars. We don't need to strdup the
name but copy and trunc into a fixed buffer.
We can also set the thread name right after we created the thread.
Emit a warning when we can't set the thread name
Make jack_client_create_thread() create FIFO threads, like the
JACK implementation did. We should probably hook that into the
module-rt functions somehow.

libcamera commit ec7afef665a87eb389a5a4cb9ff35e9c24bbcc29 (2021-06-24)
changed the name of the generated pkg-config file from 'camera.pc'
to 'libcamera.pc'.
First look for the libcamera dependency under the new name 'libcamera',
and if that's not found, look for it under the older name 'camera'.
Fixes#1355
Several places in the code don't handle reconnecting DBus connections
yet. In those cases, a ref to the DBusConnection handle needs to be
kept, so that there's no use-after-free if it gets freed by spa_dbus
if the connection is broken.
Adjust spa_dbus so that others keeping additional refs is safe.
Until now the 'v4l2' feature was not actually checking that its
required header has been found, this commit adds a check for
<linux/videodev2.h> and correctly reports both header status and whether
the feature itself ends up enabled (depends on libudev).
When a sink is RUNNING but there is nothing linked to the input it must
be the monitor that is keeping it active, report IDLE for the sink in
that case.
When a source is RUNNING but there is nothing linked to the output it
must be the sink part that is keeping it active, report IDLE for the
source.
Fixes#1345
As suggested by George Kiagiadakis, adds calls to summary() function
for each feature that is by default set to auto, so that an overview
of their effective state is printed at the end of meson setup or
meson --reconfigure command.
Currently ordering is a bit messy but tidying it up would detach
the summary() functions from the dependencies they rely on and could
be done later along with meson_options.txt re-ordering so that the
two match as much as possible.
meson.build:93: WARNING: add_languages is missing native:,
assuming languages are wanted for both host and build.
Doesn't matter for our use-case (compilation check only), so let's define it
as non-native.
