For the future, this will make it possible to provide alternative implementations of functions now stored in object_open_privsep.c. This will probably be needed by future gotd(8) which runs inside a chroot(2) environment and without the "exec" pledge(2) promise, making it impossible to run libexec helpers on the fly. Details of this design are not yet settled, but moving functions into a separate compilation unit won't hurt in any case.

Replace with got_object_commit_retain() to increment commit object reference counter. suggested by and ok stsp@

Use the & key map to enter a pattern with which to limit the displayed commits to those matching the provided pattern; similar to less(1) and mutt's limit feature. Includes various tweaks from op. ok plus fixes from op@

This allows the main process to avoid looping over all object IDs again in case the pack file used for enumeration is complete. ok op@

The problem that was found in the earlier version has been fixed. ok op@

This implementation marked commits and trees as enumerated before all trees which they depend on were enumerated. This behaviour leads to incomplete pack files when a tree is only partially packed and got-read-pack hits a missing tree entry as a result. The algorithm must be reworked such that packed leave nodes are marked enumerated first, then bubble-up. Found by op@
