I went through and did spot one conversion problem. See below.

Please always add a GOT_ prefix to macros in our headers if possible.
Use GOT_PATHLIST_FREE_NONE, etc.

Missing parentheses, and should start on bit index 0, not bit index 1.

#define GOT_PATHLIST_FREE_PATH	(1 << 0)

#define GOT_PATHLIST_FREE_DATA	(1 << 1)

free_commitable() calls free() multiple times, so unfortunately this
code cannot be converted to the new API. I would keep this as-is, and
call got_pathlist_free with GOT_PATHLIST_FREE_NONE.

Same.
