subtree(3p/cgit): merge cgit-pink into depot cgit r/4094

cgit-pink is a maintained fork of cgit that follows upstream git more
closely and already contains a lot of patches we already had applied.
Consequently, it seems sensible it becomes our future upstream, we may
even be able to upstream some of our custom, less invasive patches.
