This patch adds a new explicit Floppy Drive Type option. The existing
behavior in QEMU is to automatically guess a drive type based on the
media inserted, or if a diskette is not present, arbitrarily assign one.
This behavior can be described as "auto." This patch adds the option
to pick an explicit behavior: 120, 144, 288 or none. The new "auto"
option is intended to mimic current behavior, while the other types
pick one explicitly.
Set the type given by the CLI during fd_init. If the type remains the
default (auto), we'll attempt to scan an inserted diskette if present
to determine a type. If auto is selected but no diskette is present,
we fall back to a predetermined default (currently 1.44MB to match
legacy QEMU behavior.)
