Add an initial Stream implementation. The idea is that once capability
support is added to the library each stream will describe its
capabilities using this class. An application will then select one or
more streams based on these capabilities and use them to configure the
camera and capture.
At this stage the Stream class is empty as capabilities are yet to be
added. The class is still useful as it will be used to communicate how
many streams a Camera object provides.

Add three new classes, EventDispatcher, EventNotifier and Timer, that
define APIs for file descriptor event notification and timers. The
implementation of the EventDispatcher is meant to be provided to
libcamera by the application.
The event dispatcher is integrated twith the camera manager to implement
automatic registration of timers and events.

Introduce a Signal class that allows connecting event sources (signals)
to event listeners (slots) without adding any boilerplate code usually
associated with the observer or listener design patterns.

Provide a Camera class which represents our main interface to handling
camera devices. This is a rework of Kieran's initial proposal and
Laurent's documentation of the file changed to fit the device
enumerators needs.

The build system defines two variables, public_api and sources, that
store the names of the public headers and the source files respectively.
These files will need to be referenced when generating documentation
from source code, so let's make the variable names more descriptive:
- Rename public_api to libcamera_api and use the files() function
- Rename sources to libcamera_sources
- Add a libcamera_headers variable to hold the internal headers

Tabs are disliked within the meson build system.
Replace indentation by spaces, in all existing locations.

The include directory was defined but not installed.
Add it to the meson build structure to incorporate it as part of the
library install.
To facilitate the same include paths in our internal includes, update
the structure for headers to match the install structure.
