This defines a "reset-assert" event and a supporting utility
routine, and documents both how targets should implement it
and how config scripts should use it. Core-specific updates
are needed to make this work.

When writing to a chip's "reset yourself" register, the ARM11 code
was reporting a spurious failure. Just don't bother checking for
correctly incremented pointers given single-unit writes ... it's
a bit faster that way too. (Reads should likely do the same thing.
For that matter, such checks are usually just a waste...)
Shrink an overlong parameter name, and associated lines'o'code.

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,
but this patch fixes the immediate regressions.
Move device argument parsing after check for number of arguments;
otherwise, calling this command without any arguments would access
argv[0] before checking whether it even existed.
Fixed the header file to properly specify the doxygen documentation for the
items defined in it.

This updates the functions in the file to all have doxygen comments
describing what they do.

Created a function for copying code to the working area on
a target. The NAND write and read functions are updated to
include use of this function.

Just make these fail, instead of letting them write over
potentially random memory. Users should be able to work
around the lack of real implementations by disbling the
MMU by hand ... until someone provides a Real Fix.

Command upgrading introduced two off-by-one bugs in the flash commands.
This patch fixes the 'flash {protect,erase_sector}' commands to check
that they have been passed the correct number of arguments.
Ammended during commit to fix help text for 'erase_address' too.
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.
Use it in several places that really should be displaying
instance-specific names. Also in several places which
were already doing so, but which had no wrapper to call.

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().
