The raw object store field will contain any objects needed for
access to objects in a given repository.
This patch introduces the raw object store and populates it with the
`objectdir`, which used to be part of the repository struct.
As the struct gains members, we'll also populate the function to clear
the memory for these members.
In a later we'll introduce a struct object_parser, that will complement
the object parsing in a repository struct: The raw object parser is the
layer that will provide access to raw object content, while the higher
level object parser code will parse raw objects and keeps track of
parenthood and other object relationships using 'struct object'.
For now only add the lower level to the repository struct.
