This is not good for several reasons: - It makes the software ISP code harder to understand due to its different structuring. - Adding more algorithms may make the code harder to understand generally. - Mass libcamera code changes may not be easily applicable to software ISP. - Algorithm sharing with other pipelines is not easily possible. This patch introduces basic software ISP IPA skeletons structured similarly to the other pipelines. The newly added files are currently not used or compiled and the general skeleton structures don't contain anything particular. It is just a preparation step for a larger refactoring and the code will be actually used and extended as needed in followup patches.
