include: android: Add Android headers from Cros
Copy the Android Camera3 HAL headers from the ChromiumOS build system and define a new inclusion directive in the meson build system for them. The header files have been copied from: https://chromium.googlesource.com/chromiumos/platform2 at revision 9e65ddd2c496e712f005ada9715decd2ff8e4a03 and provide: 1) Android CameraHAL3 HAL headers in include/android/hardware/ 2) The Android system headers in include/android/system/ 3) The Android camera metadata headers in include/android/metadata/ The original path in the Cros platform2/ repository is, respectively: camera/android/header_files/include/hardware camera/android/header_files/include/system camera/android/libcamera_metadata/include/ Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

+ * IMPORTANT NOTICE:
+ *
+ * This file is part of Android's set of stable system headers
+ * exposed by the Android NDK (Native Development Kit) since
+ * platform release 1.5
+ *
+ * Third-party source AND binary code relies on the definitions
+ * here to be FROZEN ON ALL UPCOMING PLATFORM RELEASES.
+ *
+ * - DO NOT MODIFY ENUMS (EXCEPT IF YOU ADD NEW 32-BIT VALUES)
+ * - DO NOT MODIFY CONSTANTS OR FUNCTIONAL MACROS
+ * - DO NOT CHANGE THE SIGNATURE OF FUNCTIONS IN ANY WAY
+ * - DO NOT CHANGE THE LAYOUT OR SIZE OF STRUCTURES

+
+/*
+ * Support routines to send messages to the Android in-kernel log buffer,
+ * which can later be accessed through the 'logcat' utility.
+ *
+ * Each log message must have
+ * - a priority
+ * - a log tag
+ * - some text
+ *
+ * The tag normally corresponds to the component that emits the log message,
+ * and should be reasonably small.
+ *
+ * Log message text may be truncated to less than an implementation-specific
+ * limit (e.g. 1023 characters max).
+ *
+ * Note that a newline character ("\n") will be appended automatically to your
+ * log message, if not already there. It is not possible to send several messages
+ * and have them appear on a single line in logcat.
+ *
+ * PLEASE USE LOGS WITH MODERATION:
+ *
+ * - Sending log messages eats CPU and slow down your application and the
+ * system.
+ *
+ * - The circular log buffer is pretty small (<64KB), sending many messages
+ * might push off other important log messages from the rest of the system.
+ *
+ * - In release builds, only send log messages to account for exceptional
+ * conditions.
+ *
+ * NOTE: These functions MUST be implemented by /system/lib/liblog.so
