block: adjust formatting for large minors and add ext_range sysfs attr
With extended minors and the soon-to-follow debug feature, large minor
numbers for block devices will be common. This patch does the
followings to make printouts pretty.
* Adapt print formats such that large minors don't break the
formatting.
* For extended MAJ:MIN, %02x%02x for MAJ:MIN used in
printk_all_partitions() doesn't cut it anymore. Update it such that
%03x:%05x is used if either MAJ or MIN doesn't fit in %02x.
* Implement ext_range sysfs attribute which shows total minors the
device can use including both conventional minor space and the
extended one.
