Sorting headers alphabetically helps locating duplicates, and makes it
easier to figure out where to insert new headers.

There are only two headers using the K_64 custom constant. Moreover,
its usage tangles a code because the constant is defined in the C
file, while users are in the headers. Replace it with well defined
SZ_64K from sizes.h.

Instances are happier that way and it makes more sense anyway -
the only part of the result that is related to partition we are given
is the start sector, and that has been filled in by the caller.

Everything else is a function of the disk.  Only one instance
(DASD) is ever looking at anything other than bdev->bd_disk and
that one is trivial to adjust.

Fix Smatch-detected error:
drivers/block/floppy.c:3569 fd_locked_ioctl() error:
uninitialized symbol 'outparam'.

Smatch may incorrectly warn about uninitialized use of 'outparam'
in fd_locked_ioctl(), even though all _IOC_READ commands guarantee
its initialization. Initialize outparam to NULL to make this explicit
and suppress the false positive.

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

BLK_MQ_F_SHOULD_MERGE is set for all tag_sets except those that purely
process passthrough commands (bsg-lib, ufs tmf, various nvme admin
queues) and thus don't even check the flag.  Remove it to simplify the
driver interface.

Move the nonrot flag into the queue_limits feature field so that it can
be set atomically with the queue frozen.

Use the chance to switch to defaulting to non-rotational and require
the driver to opt into rotational, which matches the polarity of the
sysfs interface.

For the z2ram, ps3vram, 2x memstick, ubiblock and dcssblk the new
rotational flag is not set as they clearly are not rotational despite
this being a behavior change.  There are some other drivers that
unconditionally set the rotational flag to keep the existing behavior
as they arguably can be used on rotational devices even if that is
probably not their main use today (e.g. virtio_blk and drbd).

The flag is automatically inherited in blk_stack_limits matching the
existing behavior in dm and md.
