[Qemu-block] [PATCH 0/1] block: Eliminate the S_1KiB, S_2KiB, ... macros

[Markus Armbruster]

Back in September, Leonid Block added a whole bunch of macros (commit
540b8492618) to improve readability of qcow2.h a bit (commit
b6a95c6d100).  He later used them to fix the "vdi" driver's parameter
cluster_size's default value (commit 3dd5b8f4718).  He has now
proposed a further patch[1] to auto-generate these macros.  That patch
feels overengineered to me.

On closer examination, I found I dislike the macros before his new
patch.  So did Eric Blake.

The macros exist because the common KiB, MiB, ... macros aren't usable
when you need a literal rather than a constant expression.
stringify() does, and we use it to define the QemuOpts default value.

Eric proposed to improve QemuOpts to accept integer default values,
too[2].  Before I review that patch series, I want to establish a
"stupidest solution that can possibly work" baseline.  And that's what
this patch is.
