Hi,
at the moment, pretty much every read of target memory goes via 
target_read_memory, and then via xfer_using_stratum.

The only exception is the get_target_memory_unsigned function, which calls 
target_read function. It's the only use of 'target_read'.

The attached patch removes target_read, and makes get_target_memory_unsigned 
use target_read_memory.

OK?
