2020-04-29libcamera: Regenerate IPA module signatures at install timeLaurent Pinchart
When the IPA modules are installed, meson strips the DT_RPATH and DT_RUNPATH from the binaries. This invalidates the signatures. Disable installation of the .sign files and add an installation script to regenerate them directly in the target directory. The .sign files still need to be created at build time to support running IPA modules from the build tree. Two alternative approaches have been considered: - meson could be taught a new target argument to preserve binary compatibility by skipping any operation that modifies files. This has been proposed in the #mesonbuild IRC channel. While this could be interesting in the longer term, we need to fix the issue now. - The module signatures could be computed on selected sections only. While skipping the .dynamic section when signing may not cause security issues, it would make signature generation and verification more complex, and wasn't deemed worth it.

2020-04-16libcamera: Make IPA module signing optionalLaurent Pinchart
The IPA module signing mechanism relies on openssl to generate keys and sign the module. If openssl is not found on the system, the build will fail. Make the dependency optional by detecting openssl, and skip generation of signatures if openssl isn't found.

Add infrastructure to generate an RSA private key and sign IPA modules. The signatures are stored in separate files with a .sign suffix. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>

The isolated VIMC module isn't used in any test. Remove it to prepare for the rework of IPA module isolation. The feature can be added back later alongside corresponding tests if needed.

Give a subdirectory to all IPA modules to make the structure of the source tree more consistent. This will also simplify the implementation of IPA module selection at build time.
