[PATCH 1/5] diff.h: Make pickaxe_opts an unsigned bit field




This variable is used as a bit field[1], and as we are about to add more
fields, indicate its usage as a bit field by making it unsigned.

[1] containing the bits

    #define DIFF_PICKAXE_ALL	1
    #define DIFF_PICKAXE_REGEX	2
    #define DIFF_PICKAXE_KIND_S	4
    #define DIFF_PICKAXE_KIND_G	8
