Current implementation of virDomainBlockPull is actually a subset of
virDomainBlockRebase with NULL base.

I suggest to add new generalised API call virDomainBlockRebase2 which
will serve as a superset of both and support params list.

Having params list is more flexible and extendible for future possible
improvements of qemu block-stream or block-copy.

For now only 'base' and 'bandwidth' params are proposed, but we can
extend them, for example, to some block copy params
(VIR_DOMAIN_BLOCK_REBASE_COPY).
