monitor: Catch printing to non-existent monitor

The monitor_vprintf() function now touches the 'mon' pointer
before calling monitor_puts(), this causes block migration
to segfault as its functions call monitor_printf() with a
NULL 'mon'.

To fix the problem this commit moves the 'mon' NULL check

target-mips: add new HFLAGs for JALX and 16/32-bit delay slots

We create separate masks for the "basic" branch hflags and the
"extended" branch hflags and define MIPS_HFLAG_BMASK as the logical or
of those two.  This is done to avoid churning the codebase in lots of
different places.

We also make the execution mode an hflag under MIPS_HFLAG_TMASK

workaround for cmd646 bmdma register access while no dma is active

This is a workaround only, and is a partial revert
of a few changes to BMDMAState which removed pci_dev
field on the way.

- cmd646 pci_from_bm() expects bm->unit value to
correspond with bm data being passed to callback
as opaque pointer. This breaks when write to dma
control register of second channel happens when no
dma operation is in progress, so bm->unit is zero
for second channel, and pci_from_bm() returns garbage
pointer. Crash happens shortly after that while
dereferencing that pointer.

v0->v1: cleaned up dead code from pci_from_bm.
