The simple-cam application has a check to ensure that at least one
camera is present before attempting to access the first camera, to avoid
a crash. Update the application developer's guide to match this
behaviour.

The return type of std::vector::size() is size_t. Use the same type,
instead of unsigned int, to store its return value when retrieving the
number of allocated buffers.

When the libcamera project was started, we had no public git tree hosted
on git.libcamera.org. The problem has been addressed a while ago, and
the git.linuxtv.org libcamera repository is now a mirror of the main git
tree. The mirror is useful to benefit from the linuxtv.org automated
compile tests, but it can also confuse users who don't know where the
official version is. To try and clarify this, use the git.libcamera.org
URL consistently through the project.
This doesn't void the validatity of the linuxtv.org repository which
will continue to mirror the libcamera.org repository.

The number of metadata planes should always match the number of frame
buffer planes. Enforce this by making the vector private and providing
accessor functions.
As this changes the public API, update all in-tree users accordingly.

The CameraManager object should be deleted when it is no longer used to
prevent it from leaking.
When the application closes, the memory will be released, but it would
show up in reports from memory validation tools such as valgrind if not
handled correctly.
Recommend best-practices in the guide and ensure it is automatically
cleaned up when the CameraManager goes out of scope.

The build and run instructions read as if meson is the only way to
compile the application. Although this is recommended, it is not
required - adapt the language to fit better.
While here, fix the naming of the simple_cam meson object to match
the other usages of 'simple-cam'.

Usage of 'method' to refer to member functions comes from Java. The C++
standard uses the term 'function' only. Replace 'method' with 'function'
or 'member function' through the whole code base and documentation.
While at it, fix two typos (s/backeng/backend/).
The BoundMethod and Object::invokeMethod() are left as-is here, and will
be addressed separately.
