Make the following changes to partition check code.
* Add ->bdev to struct parsed_partitions.
* Introduce read_part_sector() which is a simple wrapper around
read_dev_sector() which takes struct parsed_partitions *state
instead of @bdev.
* For functions which used to take @state and @bdev, drop @bdev. For
functions which used to take @bdev, replace it with @state.
* While updating, drop superflous checks on NULL state/bdev in ldm.c.
This cleans up the API a bit and enables better handling of IO errors
during partition check as the generic partition check code now has
much better visibility into what went wrong in the low level code
paths.

check_partition() stops its probe once it hits an I/O error from the
partition checkers. This would prevent the actual partition checker
getting a chance to verify the partition.
So this patch lets check_partition() continue probing untill it hits a
success while recording the I/O error which might have been reported by the
checking routines.
Also, it does some cleanup of the partition methods for ibm, atari and
amiga to return -1 upon hitting an I/O error.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
