2021-08-04android: Override camera as "Internal" provided found in HAL configUmang Jain
Currently, all UVC cameras are reported with CameraLocationExternal [1] by libcamera-core since there is no universal information or standard, to know the location of these cameras. However, in the libcamera HAL layer, we can make an informed decision whether it's external or internal, simply by checking its presence in the HAL configuration file. The CameraHalManager will now assign the numerical id of the camera accordingly when initializing the CameraDevice, based on the camera facing value set in the HAL config file.

2021-08-03libcamera: base: class: Don't pass Extensible pointer to Private constructorLaurent Pinchart
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.
