The QEMU 'sendkey' command expects keys to be encoded in the same way as the RFB extended keycode set. Specifically it wants extended keys to have the high bit of the first byte set, while the Linux XT KBD driver codeset uses the low bit of the second byte. To deal with this we introduce a new keymap 'RFB' and use that in the QEMU driver * include/libvirt/libvirt.h.in: Add VIR_KEYCODE_SET_RFB * src/qemu/qemu_driver.c: Use RFB keycode set instead of XT KBD * src/util/virkeycode-mapgen.py: Auto-generate the RFB keycode set from the XT KBD set * src/util/virkeycode.c: Add RFB keycode entry to table. Add a verify check on cardinality of the codeOffset table
