2022-10-28android: remove references to std::filesystemNicholas Roth
Android 11's toolchain does not support std::filesystem, but camera_hal_config.cpp currently uses it. Remove references to std::filesystem in order to support Android <= 11. This adds a very small difference in behaviour, as File::exist() will return true for special files (pipes, character or block devices, ...) while std::filesystem::is_regular_file() doesn't, but I consider this to be a corner case that doesn't matter much.

2022-10-10libcamera: framebuffer: Move remaining private data to Private classLaurent Pinchart
Private members of the FrameBuffer class are split between FrameBuffer and FrameBuffer::Private. There was no real justification for this split, and keeping some members private in the FrameBuffer class causes multiple issues: - Future modifications of the FrameBuffer class without breaking the ABI may be more difficult. - Mutable access to members that should not be modified by applications require a friend statement, or going through the Private class. Move all remaining private members to the Private class to address the first issue, and add a Private::metadata() function to address the second problem.

Previously, ControlList::get<T>() would use default constructed objects to indicate that a ControlList does not have the requested Control. This has several disadvantages: 1) It requires types to be default constructible, 2) it does not differentiate between a default constructed object and an object that happens to have the same state as a default constructed object. std::optional<T> additionally stores the information if the object is valid or not, and therefore is more expressive than a default constructed object.

2022-06-10android: camera_device: Print the correct number of completed streamsJacopo Mondi
When a request completes, a debug message is generated to help identify the request and the number of streams it contains. The printed number of streams is however the number of output buffers requested by the camera framework, not the number of streams generated by libcamera. In facts, some output buffers are generated by post-processing, and not directly from the camera. As the debug message prints the libcamera identifier for the Request, it is more logical to print the number of streams generated by the camera instead of the total number of streams.

Add setEntry() helper, that automatically detects if updateEntry() or addEntry() should be used. Note that updateEntry() will fail if the entry was not yet added, and addEntry() will fail is the entry was already added. They are silent failures that cause unexpected values to find their way into the android metadata instance. Previously this helper was not necessary, as (with respect to the current use case) the preview template generator would always add a key so the other template generators that used the preview template as boilerplate could reliably use updateEntry(). The preview template generator will soon decide based on capabilities whether or not to add keys, so the other template generators need a helper to decide whether to use updateEntry() or addEntry(). For now only implement it for enums and arithmetic values, as they will mainly be used in populating templates.

We have some stream resolution which can provide slightly better frame duration than what we cap (i.e. 1/30 fps).
