Improve performance of large restore commands
I noticed a large (100MB) restore took hours to complete. The problem
is memory_xfer_partial repeatedly mallocs and memcpys the entire
100MB buffer for breakpoint shadow handling only to find a small
portion of it is actually written.
The testcase that originally took hours now takes 50 seconds.

* target.c (memory_xfer_partial): Cap write to 4KB.
