2020-10-28android: camera_device: Fix crash of accessing a missing map elementHirokazu Honda
std::map::at() searches std::map by the given key. The commit e1f9fdb8a5bd ("android: camera_device: Remove shadowing FrameBuffer usage") uses it with 0 to intend to accessing the first element of the map, but actually access the element whose key is nullptr. This causes the crash because the map doesn't have the element with nullptr. This fixes the issue by replacing the std::map::at() operation by std::map::begin().

2020-10-26libcamera: span: Make constructors explicit as required by C++20Laurent Pinchart
The C++20 std::span class, after which Span is modelled, specifies four constructors as explicit when extent is not dynamic_extent. Align our implementation with those requirements. A careful reviewer may notice that this change addresses five constructors, not four. The reason is that the two constructors taking Container and const Container parameters are not specified in C++20, which uses a single constructor taking a range parameter instead. As ranges are not available in C++17, the Container constructors are our best effort at providing a similar feature.

2020-10-26libcamera: controls: Disable ControlValue<T> construction from unsupported TLaurent Pinchart
The ControlValue<T> constructor for non-array values is a template function that participates in overload resolution for all T types that are not Span or std::string. Other T types that are not supported then result in a compilation error. This causes issues when calling an overloaded function that can accept both a ControlValue and a Span with an std::array<U> parameter. The first overload will be resolved using implicit construction of a ControlValue from the std::array<U>, while the second overload will be resolved using implicit construction of a Span<U> from the std::array<U>. This results in a compilation error due to an ambiguous function call. The first overload is invalid, selecting it would result in a compilation error in the ControlValue constructor, as the ControlValue<T> constructor doesn't support std::array<U> for type T. The compiler can't know about that, as overload resolution happens earlier. To fix it, we can disable the ControlValue<T> constructor for unsupported types T, moving the type check from compilation of the function to overload resolution. The constructor will not participate in overload resolution, and the call won't be ambiguous. The end result is the same for unsupported types, compilation will fail.
