This patchset is dirtylimit qtest and plan to be a supplement
for patch series "support dirty restraint on vCPU".

Dirtylimit qtest use the existing bootsect in tests/migration/i386
to start test vm. The x86.bootsect repeatedly increments the
first byte of each page in a 100MB range, so it can be a workload
for dirtylimit test.

We limit dirtyrate at one-third of origin workload to check if
dirtylimit take effect, then query the dirtylimit info and cancel
it, so all the qmp interface can be covered.  

Since the dirtylimit has not been merged yet, this patchset is
posted for RFC.

Please review, thanks !

Yong.
