2020-08-25libcamera: Remove void specifier for functions that take no argumentsLaurent Pinchart
In C++, unlike in C, a function that takes no argument doesn't need to specify void in the arguments list. Drop the unnecessary specifiers.

2020-08-23android: camera_hal_manager: Support camera hotplugUmang Jain
Extend the support for camera hotplug from libcamera's CameraManager to CameraHalManager. Use camera module callbacks to let the framework know about the hotplug events and change the status of cameras being hotplugged or unplugged via camera_device_status_change(). Introduce a map cameraIdsMap_ which book-keeps all cameras seen in the past by the CameraHalManager. If the camera is seen for the first time, a new id is assigned to it. If the camera has been seen before by the manager, its old id is reused. IDs for internal cameras start with '0' and for external cameras, they start with '1000'. Accesses to cameraIdsMap_ and cameras_ are protected by a mutex.

This fixes a bug where the luminance correction table was not being resampled according to the camera mode, in the same way as the colour tables. This could be noticeable if any camera modes crop aggressively. This resampling can be done "up front" in the SwitchMode, as we have only a single fixed luminance table. In order to protect the recalculation of the table from the asynchronous thread (which reads it) I've elected to wait for that thread to go idle (though I doubt it would have mattered much). As a by-product of stopping the thread, it no longer needs its own copy of the camera mode (async_camera_mode_).
