block-copy: streamline choice of copy_range vs. read/write
Put the logic to determine the copy size in a separate function, so
that there is a simple state machine for the possible methods of
copying data from one BlockDriverState to the other.
Use .method instead of .copy_range as in-out argument, and
include also .zeroes as an additional copy method.
While at it, store the common computation of block_copy_max_transfer
into a new field of BlockCopyState, and make sure that we always
obey max_transfer; that's more efficient even for the
COPY_RANGE_READ_WRITE case.
