Joerg Wunsch 3082630430 Replace internal knowledge in jtag3.c by a public API
In certain situations (CRC failure, device locked), that JTAG3
read functions need to return an indication to the caller that
it is OK to proceed, and allow erasing the device anyway.

Historically, the JTAG3 code passed the respective protocol
errors directly (and unexplained) up to the caller, leaving
the decision to the caller how to handle the situation.

Replace that by a more common return value API. New code should
prefer this API instead of any hardcoded return values.

Alias keyword (#868)
Implementation for an "alias" keyword.

By now, only applied inside memory descriptions.

* Make "mem_alias" a separate nonterminal.

The previous implementation attempt caused a syntax error in
yacc code, and separating mem_alias on the same level as
mem_spec appears to be the cleaner solution anyway.

* Maintain real memory aliases.

Instead of duplicating the aliased memory with a new name, maintain a
second list of memory aliases (per device) that contains a pointer to
the memory area it is aliased to. That way, a memory name can be
clearly distinguished between the canonical one and any aliases.

* Check p->mem_alias != NULL before touching it

* Add avr_find_memalias()

This takes a memory region as input, and searches whether an
alias can be found for it.

* We need to add a list structure for the mem_alias list, always.

By that means, mem_alias won't ever be NULL, so no need to check
later.

Also, in avr_dup_part(), duplicate the alias list.

* In a memory alias, actually remember the current name.

* In avr_dup_part(), adjust pointers of aliased memories

While walking the list of memories, for each entry, see if there is an
alias pointing to it. If so, allocate a duplicated one, and fix its
aliased_mem pointer to point to the duplicated memory region instead
of the original one.

* Add avr_locate_mem_noalias()

When looking whether any memory region has already been defined for
the current part while parsing the config file, only non-aliased names
must be considered. Otherwise, a newly defined alias would kick out
the memory definition it is being aliased to.

* When defining a mem_alias, drop any existing one of that name.

* Actually use avr_find_memalias() to find aliases

* Add declaration for avr_find_memalias()

* When defining a memory, also search for an existing alias

If the newly defined name has the same as an existing alias, the alias
can be removed.

Note that we do explicitly *not* remove any memory by the same name of
a later defined alias, as this might invalidate another alias'es
pointer. If someone defines that, the alias name just won't ever be
found by avr_locate_mem().

Joerg Wunsch 8c6c6a14ec Remove the "safemode" feature.
This feature has been designed with the sometimes quite flakey direct
(parallel or serial port attached) bitbang programming adapters in
mind that were quite common about two decades ago.

With parallel ports vanishing from modern PCs almost completely, and
the advent of various USB-attached low-cost programming devices,
this class of programmers disappeared almost completely.

Furthermore, the fuse combinations that were covered by the feature
are no longer around on all recent AVR devices, so for an ever
increasing number of devices, safemode already became meaningless and
was turned off anyway.

With the prospective version 7.x release, it's a good point in time to
introduce a major change like this one.
