The width of opt_io_size in virtio_blk_config is 32bit. However, it's
written with virtio_stw_p; this may result in value truncation, and on
big-endian systems with legacy virtio in completely bogus readings in
the guest.
Use the appropriate accessor to store it.

Several block device properties related to blocksize configuration must
be in certain relationship WRT each other: physical block must be no
smaller than logical block; min_io_size, opt_io_size, and
discard_granularity must be a multiple of a logical block.
To ensure these requirements are met, add corresponding consistency
checks to blkconf_blocksizes, adjusting its signature to communicate
possible error to the caller. Also remove the now redundant consistency
checks from the specific devices.

Make it easier (more visible) to maintain the limits on the blocksize
properties in sync with the respective description, by using macros both
in the code and in the description.

Several BlockConf properties represent respective sizes in bytes so it
makes sense to accept size suffixes for them.
Turn them into uint64_t and use size-suffix-capable setters/getters on
them.
Also, as some of them are exposed to the guest by scsi and virtio-blk
devices as an integer of a specific width (uint16_t for min_io_size and
uint32_t for opt_io_size and discard_granularity) in units of logical
blocks, introduce extra checks in blkconf_blocksizes to prevent their
silent truncation.

Logical and physical block sizes in QEMU are limited to 32 KiB.
This appears unnecessary tight, and we've seen bigger block sizes handy
at times.
Lift the limitation up to 2 MiB which appears to be good enough for
everybody, and matches the qcow2 cluster size limit.
