Since we're converting the swcr to fpcr format for exceptions,
it's trivial to add FPCR_DNZ to the set of fpcr bits overriden.

The CONFIG_USER_ONLY adjustment blindly mashed the swcr
exception enable bits into the fpcr exception disable bits.
However, fpcr_exc_enable has already converted the exception
disable bits into the exception status bits in order to make
it easier to mask status bits at runtime.
Instead, merge the swcr enable bits with the fpcr before we
convert to status bits.

Since 9458a9a1df, all readers of the dirty bitmaps wait
for the rcu lock, which means that they wait until the end
of any executing TranslationBlock.
As a consequence, there is no need for the actual access
to happen in between the _prepare and _complete. Therefore,
we can improve things by merging the two functions into
notdirty_write and dropping the NotDirtyInfo structure.
In addition, the only users of notdirty_write are in cputlb.c,
so move the merged function there. Pass in the CPUIOTLBEntry

Various parts of the migration code do different things when they're
in postcopy mode; prior to this patch this has been 'postcopy-active'.
This patch extends 'in_postcopy' to include 'postcopy-paused' and
'postcopy-recover'.
In particular, when you set the max-postcopy-bandwidth parameter, this
only affects the current migration fd if we're 'in_postcopy';
this leads to a race in the postcopy recovery test where it increases
the speed from 4k/sec to unlimited, but that increase can get ignored
if the change is made between the point at which the reconnection
happens and it transitions back to active.
