blob_item patch

[Russ D. <ru...@in...>]

This patch gets rid of all the kernelSize, kernelType, paramSize, etc
defines in blob_status_t and replaces them each with a blob_item_t
struct:

typedef struct {
        int size;
        block_source_t type;
        u32 *addr;
        u32 md5_digest[4];
} blob_item_t;

This helps generalize and simplify a lot of the code. Let me know what
you think of the patch.
