    • maps: provide high-level iteration interface · 18cf5698
      Currently, our headers need to leak some implementation details of maps due to
      their direct use of indices in the implementation of their foreach macros. This
      makes it impossible to completely hide the map structures away, and also makes
      it impossible to include the khash implementation header in the C files of the
      respective map only.
      
      This is now being fixed by providing a high-level iteration interface
      `map_iterate`, which takes as inputs the map that shall be iterated over, an
      iterator as well as the locations where keys and values shall be put into. For
      simplicity's sake, the iterator is a simple `size_t` that shall initialized to
      `0` on the first call. All existing foreach macros are then adjusted to make use
      of this new function.

    • maps: provide a uniform entry count interface · 7e926ef3
      There currently exist two different function names for getting the entry count
      of maps, where offmaps offset and string maps use `num_entries` and OID maps use
      `size`. In most programming languages with built-in map types, this is simply
      called `size`, which is also shorter to type. Thus, this commit renames the
      other two functions `num_entries` to match the common way and adjusts all
      callers.

    • Share packs across repository instances · b3b66c57
      Opening the same repository multiple times will currently open the same
      file multiple times, as well as map the same region of the file multiple
      times. This is not necessary, as the packfile data is immutable.
      
      Instead of opening and closing packfiles directly, introduce an
      indirection and allocate packfiles globally. This does mean locking on
      each packfile open, but we already use this lock for the global mwindow
      list so it doesn't introduce a new contention point.
