Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.
Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

My previous commit, f92f8afebe, broke -vnc (spotted by Glauber Costa). This
is because it's necessary to tell when the no special display parameters have
been passed and default to SDL or VNC appropriately.
This refactors the display selection logic to be less complicated which has
the effect of fixing the regression mentioned above.

fw_cfg_add_callback() checks if key has FW_CFG_WRITE_CHANNEL bit set
after masking the key with FW_CFG_ENTRY_MASK.
But as FW_CFG_ENTRY_MASK is ~(FW_CFG_WRITE_CHANNEL | FW_CFG_ARCH_LOCAL),
the bit is never set and function exits.
This patch corrects this by checking the bit before masking the value.
