Draft: ocaml aports

Building on the work omni did in !25782 (closed)

I had to modify the patches a little bit in order to get them to apply to the current git tree. I needed to remove the references to mips and mips64, and for ocaml-calendar, pkgrel was bumped from 1 to 3, so I fixed that.

There were also 5 patches that I did not apply, most of them due to the aports already being updated:
