Origami v0.5.1

Big iron graphics. The Onyx 3000 with its V-brick VPro V12 and the Onyx 3400
with G-brick InfiniteReality3 are presets, and the Onyx 3400 takes up to four
pipes, each with a two-head DG5-2 display. IRIX 6.5.30 reaches the 4Dwm
desktop on every pipe, and one pipe's two heads join into a 2560x1024 desktop.

• New:
  • Presets onyx3000-vpro and onyx3400-infinite-reality.
  • create --graphics-pipes N fits several pipes: 1 to 4 on the Onyx 3400
    and 1 to 2 on onyx2-rack-infinite-reality, whose second pipe gets the
    second node it needs.
  • A pipe's two heads join into one 2560x1024 desktop once ircombine
    stores the shipped 2@1280x1024_60 in the pipe's flash: the next start
    comes up that way. The usage guide has the command.
  • run shows every head of every pipe: a window for each head, or with
    --display vnc a VNC server for each on consecutive ports from
    --vnc-port.
• Changed:
  • Each InfiniteReality pipe keeps its flash in the machine's state as
    SLOT-kona-flash.raw. origami upgrade adds it to machines made
    before 0.5.1; without it QEMU refuses to start the machine.
• QEMU updated to 29ffcfb163. The Onyx 3000 boots without brick-type warnings from the PROM.
