[3/6] ds: Debug removal, status copying, debug output changes, big functionality extension.

[Evgeniy Polyakov]

      Debug removal, status copying, debug output changes,
ds_wait_status(), ds_touch_bit(), ds_recv_data() changes, struct
ds_status changes.
    Revision:
      ds9490r--main--0.1--patch-3
 
    Removed some debug printks.
    Typo in status copying code - s/sizeof(st)/sizeof(*st).
    Changed debug output: exchanged input and output buffer status,
since they need(and already are) to be exchanged in struct ds_status.
    ds_wait_status() - waits until max attempts or error occures.
    ds_touch_bit() - typo in "value" parameter[I wonder if Dallas even
tries to compile their cruft with non MS compiler],
        waits untill max attempts or last command in status is equal to
"value".
    ds_recv_data() returns negative error code or number of bytes read.
    Exchanged input and output buffer status instruct ds_status.
 
    modified files:
     Makefile dscore.c dscore.h
