Prepare for new components in avrdude.conf incl prog_modes
- Add prog_modes to part and programmer definitions; prog_mode is a bitwise
   or of programming modes
     + PM_SPM: Bootloaders, self-programming with SPM/NVM Controllers
     + PM_TPI: t4, t5, t9, t10, t20, t40, t102, t104
     + PM_ISP: SPI programming for In-System Programming (typ classic parts)
     + PM_PDI: Program and Debug Interface (xmega parts)
     + PM_UPDI: Unified Program and Debug Interface
     + PM_HVSP: High Voltage Serial Programming (some classic parts)
     + PM_HVPP: High Voltage Parallel Programming (most non-HVSP classic parts)
     + PM_debugWIRE: Simpler alternative to JTAG (a subset of HVPP/HVSP parts)
     + PM_JTAG: some classic parts, some xmega
     + PM_aWire: AVR32 parts
 - Add mcuid, a unique id in 0..2039, to part definition for urclock programmer
 - Add n_interrupts, the number of interrupts, to part definition
 - Add n_page_erase to part definition (# of pages erased during NVM erase)

 - Implement a simple calculator in config_gram.y so numeric values can be
   expressed as simple expressions such as PM_SPM | PM_UPDI

 - Introduce a new method of assigning simple components to the grammar without
   touching config_gram.y via an eligible-component list in config.c; numeric
   expressions on the rhs of an assignment resolve to integer values

 - Update documentation in avrdude.conf.in and avrdude.texi

Replace string arrays with const char * and allocated space (part 2)
This commit replaces fixed-string buffers in PROGRAMMER, AVRPART and AVRMEM
that are dealt with by the parser and grammar. Now, string assignments are
always to const char *, ie, these are read-only strings with arbitrary
length.

config_gram.y now only needs to consider one type of string assignment.

This commit also

  - Replaces the simple linear-search cache_string() function with faster
    hashed cache_string(). Either way, the returned value is likely to be
    shared, so should never be free()'d.

  - Duplicates hvupdi_support list in pgm_dup() and frees it in pgm_free()

  - Adds const qualifier to some function args in avrpart.c and pgm.c

  - Hardens some functions against being called with NULL pointers

  - Ensures _new() and _dup() functions for parts, programmers and memory
    return a suitable memory. Out of memory triggers exit in one of three
    functions, cfg_malloc(), cfg_realloc() and cfg_strdup(); there is
    rarely anything useful that AVRDUDE or, for that matter, any
    application compiled against libavrdude can do once you run out of
    memory as AVRDUDE/libavrdude rely heavily on allocation of memory.

Harden string processing during parsing in lexer.l, config_gram.y and otherwise
- Replace strdup(s) with cfg_strdup(funname, s) that exits on out of mem
 - Replace malloc(n) with cfg_malloc(funname, n) that exits on out of mem
 - Change multiline string scanning in lexer.l to avoid core dump
 - Remove global variables string_buf and string_bug_ptr
 - Ensure reading strings unescapes strings C-Style
 - Ensure writing strings escapes strings C-Style again

Commit looks longer than needed as unescape() and auxiliary functions needed
to be moved from term.c (not in libavrdude) to config.c (in libavrdude).

Stefan Rueger f95a1d3448 Cache config_file components in AVRPART and PROGRAMMER structures
Some 90% of the space of AVRPART and some 50% of PROGRAMMER is occupied by a
4 kB array config_file[] that contains the configuration file name. In
preparation of developer options that output a raw dump of the part
descriptions, this commit changes the config_file components from a large
array, which is duplicated in each part and programmer description, to a
cached string for each config file allowing for smaller raw dumps.

This commit also changes the config file name to its realpath(), eg, shortens
unwarranted `/bin/../etc/` file name components. It also changes the global
variable names `infile` and `fileno` to cfg_infile and cfg_fileno for an ever
so slight improvement of code clarity.

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.
