[libcamera-devel] libcamera Android Enhancements, V2

[nicholas at rothemail.net]

All,

Thanks for your initial round of comments on my proposed changes.
These patches break the work into separate commits and make other
requested adjustments.

Original email (partial):
These are the major changes:
* Adds Makefiles that allow mainline libcamera to build in-place with Android distributions, including Waydroid
* Fixes Bug 159 (see Bugzilla), an LLVM bug that breaks libcamera on Android 11 and below, which Waydroid uses
* Adds a flag that allows unsigned IPAs to run in-process with a stern warning, because openssl and gnutls do not have mainiline Android builds
* Adds log messages to help people identify and fix issues (e.g., HAL configuration file IDs)
* Adds thread-safety annotations for the raspberry pi IPA to allow it to build for Android
* Adds metadata to the rkisp1 IPA that make it compatible with the HAL implementation
* Adds metadata for the PinePhone Pro's image sensors based on mainline Linux drivers

Thanks again, and I look forward to reading your responses.
