bootutil: add accessors for sector size and number

Taking the opportunity to move some signed integers over to unsigned
size_t as we go. (Depending on compiler settings, signed / unsigned
comparisons can generate warnings, so it's nice to use the signedness
we mean when possible).

Having boot_img_set_num_sectors() is just an intermediate step; this
gets cleaned up as we go forward.
