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

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.

Implement the D-Pointer design pattern in the FrameBuffer class to allow
changing internal data without affecting the public ABI.
Move the request_ field and the setRequest() function to the
FrameBuffer::Private class. This allows hiding the setRequest() function
from the public API, removing one todo item. More fields may be moved
later.

libcamera names header files based on the classes they define. The
buffer.h file is an exception. Rename it to framebuffer.h.
