[Qemu-block] [PATCH v1 0/1] qemu-img: add new function to remove bitmap in image

[Ma Haocong]

Hello,

In our scene, we need to delete dirty-bitmap created by using qmp command 
'block-dirty-bitmap-add'. we can use qmp command 'block-dirty-bitmap-remove'
to remove bitmap. Then I think that we should add a new function in qemu-img
to do the same work. 

The command format is: qemu-img removebmp file-name bitmap-name

I test the function by using qmp command to create a named dirty-bitmap in
qcow2 image, then shutdown the vm and using qemu-img to remove it. Then I
test to remove a bitmap with 'IN_USE' flags in qcow2 file, and it works.
I alse test to do the same job to the qcow2 image encrypted by luks.

Please help to review. Thanks.
