The processing of the scancodes for PAUSE/BREAK has been broken since
the conversion to qcodes in:

ps2: use QEMU qcodes instead of scancodes
When using a VNC client, with the raw scancode extension, the client
will send a scancode of 0xc6 for both PAUSE and BREAK. There is mistakenly
no entry in the qcode_to_number table for this scancode, so
ps2_keyboard_event() just generates a log message and discards the
scancode
When using a SPICE client, it will also send 0xc6 for BREAK, but
will send 0xe1 0x1d 0x45 0xe1 0x9d 0xc5 for PAUSE. There is no
entry in the qcode_to_number table for the scancode 0xe1 because
it is a special XT keyboard prefix not mapping to any QKeyCode.
Again ps2_keyboard_event() just generates a log message and discards
the scancode. The following 0x1d, 0x45, 0x9d, 0xc5 scancodes get
handled correctly. Rather than trying to handle 3 byte sequences
of scancodes in the PS/2 driver, special case the SPICE input
code so that it captures the 3 byte pause sequence and turns it
into a Pause QKeyCode.
