[PATCH v2 21/24] fast-import: add helper function for inserting mark object entries

From

<20200222201749.937983-1-sandals@crustytoothpaste.net>

Currently, everything we want to insert into a mark set is an object entry. However, in the future, we will want to insert objects of other types. Teach read_mark_file to take a function pointer which helps us insert the object we want into our mark set.
