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.

Replace string arrays with const char * and allocated space (part 1)
This commit deals with default_programmer, default_serial, default_parallel
and default_spi. The long term objective is to remove all fixed-size buffers
from the structures that lexer.l and config_gram.y deal with.

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).

Establish a third option to print out part definitions
Introduced -p <part>/A, which prints what -p <part>/S used to print, ie, all
components of the part structures including the default ones. Now -p <part>/S
prints the expanded part structure without use of parent and without printing
default values. This functionality is new and predominantly needed for
checking specific avrdude.conf entries, eg, avrdude -p*/St | grep pollindex

The option -p <part>/s continues to print a short entry of `avrdude.conf`
using its parent if so defined:

$ avrdude -p m328p/s

part parent "m328"
    desc                = "ATmega328P";
    id                  = "m328p";
    signature           = 0x1e 0x95 0x0f;

Stefan Rueger 3412196cd9 Weaken -U memory type check and move after config file parsing in main.c
The check for typos in -U memory names against a list of known memory names
now happens after the config files have been read, so newly declared memory
names can be considered. This commit also weakens the check against existence
of a known memory: it is now sufficent for a name to pass when it could be
the initial string of any known memory of any part. Any -U memory that cannot
possibly be matched up with a known memory is considered a typo and leads to
an exit before the programmer is opened.

This to protect users from typos that leave a device partially programmed.

When every -U memory name might be matching one of the known memories, the
programming is attempted. If the part to be programmed turns out not to have
a particular -U memory, AVRDUDE warns the user and skips this -U update.

This to support unifying interfaces that call AVRDUDE with potentially more
memories than the actual part has (eg, efuse on ATmega8).

Stefan Rueger 02027ab766 Enable stdin verification and display correct number of bytes written/verified
Counting the number of bytes written to a memory and/or verified is not
trivial owing to potential holes in the input file and to potential trailing
0xff bytes in flash memory that are not written per default (but see -A). The
new function memstats(), which is best called just after an input file has
been read into mem->buf/mem->tags, computes the right number of bytes written
and allows easy computation of the number of bytes verified.

This commit also changes the strategy for the default verification after
writing to a chip memory, so that the input file only needs reading once thus
enabling successful verification of stdin input files.

Other, minor changes:
 - Improving the grammar of AVRDUDE output, eg, 1 byte written instead of
   1 bytes written
 - Better description of the input file structure in terms of its sections,
   the interval it spans, the number  of pages, the number of padding bytes
   in pages, and the number of actually cut off trailing 0xff bytes for flash
 - Printing <stdin> or <stdout> instead of - in the -U routines
 - Option -V no longer needs to be specified before option -U in order to work

As an aside this commit also provides useful helper functions for printing
plural(), inname(), outname() and interval() all of which return strings fit
for printing.

Deprecate original STK500 v1 protocol in favour of optiboot and Arduino as ISP
For paged read/write early AVRDUDE implementations of the STK500 v1 protocol
communicated a word address (below a_div=2) or byte address (a_div=1) based
on the following code irrespective of which memories were used:

  if(m->op[AVR_OP_LOADPAGE_LO] || m->op[AVR_OP_READ_LO])
    a_div = 2;
  else
    a_div = 1;

This turned out to be a bug: it really should have been a_div=2 for flash and
a_div=1 for eeprom. At the time presumably no one noted because Atmel was at
the cusp of replacing their FW 1.x with FW 2 (and the STK500 v2 protocol).

It seems that the world (optiboot, Arduino as ISP, ...) has compensated for
the bug by assuming AVRDUDE sends *all* eeprom addresses as word addresses.
Actually these programmers overcompensated for the bug because for six out of
the 146 known SPI programmable parts with eeprom and page size > 1, AVRDUDE
would still send the eeprom addresses as byte addresses (ATmega8 ATmega8A
ATmega64 ATmega64A ATmega128 ATmega128A) owing to above code.

It makes no sense to correct the bug now seeing that virtually no one uses
the old 2005 STK 500 v1 firmware. This commit now follows optiboot, Arduino
as ISP and other projects, and simply sends all addresses for paged read or
write as word addresses. There are no longer (little known) exceptions for
ATmega8 et al that surprised some optiboot etc users.

Joerg Wunsch cc93bd2c83 Move the error handling for invalid file formats to fileio.c
The checks used to be in update.c, but as they are related to
the intended file operation, they are better placed in fileio.c.

The checks affected are to refuse 'm' on output (file write),
and 'd', 'h', 'o', and 'b' formats on input (file read).
