/*
 * define_commit_slab(slabname, elemtype) creates boilerplate code to define
 * a new struct (struct slabname) that is used to associate a piece of data
 * of elemtype to commits, and a few functions to use that struct.
 *
 * After including this header file, using:
 *
 * define_commit_slab(indegree, int);
 *
 * will let you call the following functions:
 *
 * - int *indegree_at(struct indegree *, struct commit *);
 *
 *   This function locates the data associated with the given commit in
 *   the indegree slab, and returns the pointer to it.  The location to
 *   store the data is allocated as necessary.
 *
 * - int *indegree_peek(struct indegree *, struct commit *);
 *
 *   This function is similar to indegree_at(), but it will return NULL
 *   until a call to indegree_at() was made for the commit.
 *
 * - void init_indegree(struct indegree *);
 *   void init_indegree_with_stride(struct indegree *, int);
 *
 *   Initializes the indegree slab that associates an array of integers
 *   to each commit. 'stride' specifies how big each array is.  The slab
 *   that is initialized by the variant without "_with_stride" associates
 *   each commit with an array of one integer.
 *
 * - void clear_indegree(struct indegree *);
 *
 *   Empties the slab.  The slab can be reused with the same stride
 *   without calling init_indegree() again or can be reconfigured to a
 *   different stride by calling init_indegree_with_stride().
 *
 *   Call this function before the slab falls out of scope to avoid
 *   leaking memory.
