The Camera::Private class is defined in camera.cpp. To prepare for
allowing it to be subclassed by pipeline handlers, move it to a new
internal/camera.h header.
The \file comment block in camera.cpp now needs to explicitly tell which
camera.h file it refers to.

The FrameBuffer::Private class is exposed to pipeline handlers, and is
thus part of the internal libcamera API. As such, it should be

The Extensible and Extensible::Private classes contain pointers to each
other. These pointers are initialized in the respective class's
constructor, by passing a pointer to the other class to each
constructor. This particular construct reduces the flexibility of the
Extensible pattern, as the Private class instance has to be allocated
and constructed in the members initializer list of the Extensible
class's constructor. It is thus impossible to perform any operation on
the Private class between its construction and the construction of the
Extensible class, or to subclass the Private class without subclassing
the Extensible class.
To make the design pattern more flexible, don't pass the pointer to the
Extensible class to the Private class's constructor, but initialize the
pointer manually in the Extensible class's constructor. This requires a
const_cast as the o_ member of the Private class is const.

It would be convenient to be able to iterate over available boolean
values, for example for controls that designate if some function can be
enabled/disabled. The current min/max/def constructor is insufficient,
as .values() is empty, so the values cannot be easily iterated over, and
creating a Span of booleans does not work for the values constructor.
Add new constructors to ControlInfo that takes a set of booleans (if
both booleans are valid values) plus a default, and another that takes
only one boolean (if only one boolean is a valid value).
Update the ControlInfo test accordingly.

When RPiCameraData::clearIncompleteRequests() clears out the request
queue during a stop condition, it unconditionally calls completeBuffer()
on all buffers in each request. This is wrong, as a buffer could have
already been completed as part of the current request, but the request
itself may not yet have completed.
Fix this by checking if the buffers in the request have been completed
before cancelling them.

There are use cases for calling the dispatchMessages() function
recursively, from within a message handler. This can be used, for
instance, to force delivery of messages posted to a thread concurrently
to stopping the thread. This currently causes access, in the outer
dispatchMessages() call, to iterators that have been invalidated by
erasing list elements in the recursive call, leading to undefined
behaviour (most likely double-free or other crashes).
Fix it by only erasing messages from the list at the end of the outer
call, identified using a recursion counter.

The libcamera-base.so will feature internal support functionality
that is utilised by libcamera, and can be shared in other places.
This new library provides a layer beneath libcamera which provides
common abstractions to internal objects.
A pkg-config file is generated and named libcamera-base.pc which allows
components such as external IPA modules to link directly to this library
if they need. Normal applications will reference this library through
the Requires: statement provided by the libcamera.pc package
configuration, and linkage will be handled automatically through the
pkg-config mechanisms.
No code is moved to this library yet, this patch only introduces the
framework, construction and linkage.

The libcamera library is moved to the first positional argument of the

values for the package.
As part of this, the shared library name is adjusted to the full library
name 'libcamera', without relying upon the automatic 'lib' prefix which
better represents the component and naming of the library.
As a result of this, the pkgconfig file is now named 'libcamera.pc' as
opposed to 'camera.pc', and applications desiring to reference libcamera
will need to search for 'libcamera' as a dependency rather than
'camera'.
The library itself is still created and installed as 'libcamera.so'.

- dependency('camera', required : true),
