libcamera v0.0.3

Key bug fixes:

 * Segfault in the ContolInfo() constructor for an empty V4L2 menu
   Bug: https://bugs.libcamera.org/show_bug.cgi?id=167
   Fix: libcamera: v4l2_device: Workaround faulty control menus

   This resolves and prevents crashes that have occured in Pipewire when
   users connect poorly implemented UVC devices.

ABI Compliance:

abi-compliance-checker reports 100% ABI and API compatibility with with
v0.0.2, however 81e7689bb168 ("libcamera: stream: Turn StreamRole into
scoped enumeration") modifies an enum into a class enum. This may need
minor updates to applications, and didn't appear to be picked up by
abi-compliance-checker.

- See https://git.libcamera.org/libcamera/libcamera.git/commit/?id=81e7689bb168a for more details.

Highlights:

Core:
 * Fix tracing when built as a subproject
 * Avoid double map lookups in framebuffer_allocator
 * Workaround faulty control menus
 * controls: Change LensPosition units to dioptres
 * camera_sensor: Add IMX519 sensor properties
 * Documentation: contributing: Add commit message guidelines
 * Declare generic converter interface

utils:
 * Add libtuning
 * Add initial libtuning script support for rkisp1 and raspberrypi.
 * checkstyle.py: Check new header file on new and renamed meson.build files

ipa:
 * Move IPA sensor controls validation to CameraSensor (IPU3/RKISP1)

rkisp1:
 * Support FrameDurationLimits control for FrameRate management
 * Support raw capture (IPA, configuration, and runtime)
 * Add support for manual gain and exposure
 * Fix stream size validation
 * Add additional default values to controls

imx8-isi:
 * Enumerate supported stream formats
 * Set SensorTimestamp metadata

Raspberry Pi:
 * Remove generic "pause" mechanism from Algorithm
 - Remove enum BuffferMask from the mojom interface
 - Fix digital gain calculations for manual mode
 - Fix bug in IPA frame drop logic
 - imx477: Update tuning file for the latest camera modules
 - Add a "scientific" tuning for the IMX477

Apps:
 - cam: kms: Avoid 'unused-parameter' warnings
 - cam: Support parsing array controls in capture scripts
 - gstreamer: Improve control id lookups
 - lc-compliance: simple_capture: Free Requests properly

python:
 - Support controls that use an array of Rectangles
 - Expose the Request Sequence Number in Python Bindings

test:
 - Validate CameraSensor Ancillary Devices (focusLens)
 - controls: control_info: Test default def() values

libcamera v0.0.2

This release contains all the work merged to libcamera over the last 5
weeks, including the following summary highlights:

Highlights:

Core:
 * New pipeline handler for the IMX ISI
 * Fixed memory leak in the logging infrastructure
 * Fixed meson support for 0.56
 * Additional Thread Safety annotations added throughout
 * Add a release method to pipeline handlers to support
   freeing resources when a camera is released, but not
   deleted.
 * Group test applications under src/apps
 * Make libdl optional to support Android builds

Application layers:
 * Added DNG File output to cam
 * Fixes for building against Android
 * gstreamer framerate control and negotiation

IPA:
 * Support setting metadata directly from (libipa) algorithms
 * Set AGC and AWB metadata for both RKISP1 and IPU3.
 * Support for enum serialization and Flags
 * Support multiple lens shading tables for different colour
   temperatures on RKISP1/i.MX8MP.

Raspberry Pi IPA:
 * Full line length control
 * Better HBLANK synchronisation and full line length control
 * Support ov9281 as ov9281_mono
 * Update colour temperature whenever manual gains change

abi-compliance-checker tells me that this release is 100% abi compatible
with v0.0.1.
