[Qemu-devel] [PATCH v2 15/24] util/cutils: Rename qemu_strtosz() to qemu_strtosz_MiB()

[Markus Armbruster <armbru@redhat.com>]

With qemu_strtosz(), no suffix means mebibytes.  It's used rarely.
I'm going to add a similar function where no suffix means bytes.
Rename qemu_strtosz() to qemu_strtosz_MiB() to make the name
qemu_strtosz() available for the new function.
