Instead of checking against busy, inconsistent, or read only directly, use a check function with permissions bits that let us streamline the checks without reproducing them in many places. Included in this patch are permissions changes that simply add the inconsistent check to existing permissions call spots, without addressing existing bugs. In general, this means that busy+readonly checks become BDRV_BITMAP_DEFAULT, which checks against all three conditions. busy-only checks become BDRV_BITMAP_ALLOW_RO. Notably, remove allows inconsistent bitmaps, so it doesn't follow the pattern.
