Instead of reinventing a simply linked list, reuse the list helper
for the list of targets in a smp cluster.
Using the existing helper, that implements a double linked list,
makes trivial going through the list in reverse order.

The NULL pointers preceded by cast where not detected by the
scripting tools looking for NULL pointer comparison.
Remove them and, while there, further simplify the code and apply
the other coding style rules.

To prepare for handling TCL return values consistently, all calls
to command_print/command_print_sameline should switch to CMD as
first parameter.
Change prototype of command_print() and command_print_sameline()
to pass CMD instead of CMD_CTX.
Since the first parameter is currently not used, the change can be
done though scripts without manual coding.
This patch is created using the command:
sed -i PATTERN $(find src/ doc/ -type f)
with all the following patters:
's/\(command_print(cmd\)->ctx,/\1,/'
's/\(command_print(CMD\)_CTX,/\1,/'
's/\(command_print(struct command_\)context \*context,/\1invocation *cmd,/'
's/\(command_print_sameline(cmd\)->ctx,/\1,/'
's/\(command_print_sameline(CMD\)_CTX,/\1,/'
's/\(command_print_sameline(struct command_\)context \*context,/\1invocation *cmd,/'
This change is inspired by http://openocd.zylin.com/1815 from Paul
Fertser but is now done through scripting.

Depending on range size, the loop on cache operations can take quite
some time, causing gdb to timeout.
Add keep-alive to prevent gdb to timeout.
Add also a missing dpm->finish() to balance dpm->prepare().

D-Cache invalidate is a dangerous operation. It will only work correctly
if full cache lines are invalidated. When partial cache lines are
invalidated, i.e. the target address range does not start and end
at a cache line boundary, cpu data writes outside of the target range
will be dropped. This patch adds special treatment for partial cache
lines by doing a clean & invalidate on the partial lines before
invalidating the rest of the range.

ARMv7 architecture allows up to 7 cache levels that are architecturally
visible, as opposed to "system caches", which are outside of the domain
defined by ARMv7 and require separate management. This patch enables
detection and identification of caches at all levels. It also implements
a new "flush-all" function that cleans & invalidates all cache levels to
the "Point of Coherence".
