fix regression causing duplicated output
The command refactoring caused subcommand handlers to produce duplicate
output when run. The problem was introduced by failing to ensure all
such invocations went through a top-level "catcher" script, prefixing
the command name with the 'ocd_' prefix and consuming its results.
The fix is to ensure such a top-level "catcher" script gets created
for each top-level command, regardless of whether it has a handler.
Indeed, this patch removes all command registrations for sub-commands,
which would not have worked in the new registration scheme anyway.
For now, dispatch of subcommands continues to be handled by the new
'unknown' command handler, which gets fixed here to strip the 'ocd_'
prefix if searching for the top-level command name fails initially.
Some Jim commands may be registered with this prefix, and that situation
seems to require the current fallback approach. Otherwise, that prefix
could be stripped unconditionally and the logic made a little simpler.
The same problem must be handled by the 'help' command handler too,
so its lookup process works as intended.
Overall, the command dispatching remains more complicated than desired,

target: create and use target_name()
Several of the sites now using target_type_name() really
ought to be using an instance-specific name. Create a
function called target_name(), accessing the instance's
own (command) name.

instance-specific names. Also in several places which
were already doing so, but which had no wrapper to call.

target: target_get_name() --> target_type_name()
There are two names that may matter on a per-target basis.
One is a per-instance name (for example, "at91sam7s.cpu").
The other is the name of its type (for example, "arm7tdmi"),
which is shared among multiple targets.
Currently target_get_name() returns the type name, which is
misleading and is rarely appropriate for target diagnostics.
Rename that as target_type_name().
