Review and overhaul AVRDUDE's messaging system (#1126)
* Change avrdude_message(MSG_XYZ, ...) to msg_xyz(...)
* Define and use pmsg_xyz(...) instead of msg_xyz("%s: ...", progname, ...)
* Review and change avrdude_message() levels
   - Introduce new levels warning, error and ext_error
   - Distribute info level to info, warning, error, ext_error
   - Assign levels (more) consistently
   - Unify grammar, punctuation and style of messages
* Use imsg_xyz() to print indented messages
* Show function name in errors and warnings on -v
* Reduce effective verbosity level by number of -q above one

Offload the programming interface info from part->flags to part->prog_modes
flags now just hold parameters of the JTAG interface and some secondary
serial, parallel, pseudo parallel info. This separation brings clarity. It
used to be hard to augur whether a part has an ISP interface:

   (part->flags & (AVRPART_HAS_PDI | AVRPART_AVR32 | AVRPART_HAS_TPI
    | AVRPART_HAS_UPDI)) == 0 && (part->flags & AVRPART_SERIALOK) != 0

or had HVSP or HVPP capability, for that matter. Now it is just, eg,

  part->prog_modes & PM_ISP
  part->prog_modes & PM_HVPP

Use const in PROGRAMMER function arguments where appropriate
In order to get meaningful const properties for the PROGRAMMER, AVRPART and
AVRMEM arguments, some code needed to be moved around, otherwise a network of
"tainted" assignments risked rendering nothing const:

 - Change void (*enable)(PROGRAMMER *pgm) to void (*enable)(PROGRAMMER *pgm,
   const AVRPART *p); this allows changes in the PROGRAMMER structure after
   the part is known. For example, use TPI, UPDI, PDI functions in that
   programmer appropriate to the part. This used to be done later in the
   process, eg, in the initialize() function, which "taints" all other
   programmer functions wrt const and sometimes requires other finessing with
   flags etc. Much clearer with the modified enable() interface.

 - Move TPI initpgm-type code from initialize() to enable() --- note that
   initpgm() does not have the info at the time when it is called whether or
   not TPI is required

 - buspirate.c: move pgm->flag to PDATA(pgm)->flag (so legitimate
   modification of the flag does not change PROGRAMMER structure)

 - Move AVRPART_INIT_SMC and AVRPART_WRITE bits from the flags field in
   AVRPART to jtagmkII.c's private data flags32 fiels as FLAGS32_INIT_SMC and
   FLAGS32_WRITE bits

 - Move the xbeeResetPin component to private data in stk500.c as this is
   needed by xbee when it saddles on the stk500 code (previously, the flags
   component of the part was re-dedicated to this)

 - Change the way the "chained" private data are used in jtag3.c whilst
   keeping the PROGRAMMER structure read-only otherwise

 - In stk500v2.c move the STK600 pgm update from stk500v2_initialize() to
   stk500v2_enable() so the former keeps the PROGRAMMER structure read-only
   (for const assertion).

 - In usbasp change the code from changing PROGRAMMER functions late to
   dispatching to TPI or regular SPI protocol functions at runtime; reason
   being the decision whether to use TPI protocol is done at run-time
   depending on the capability of the attached programmer

Also fixes Issue #1071, the treatment of default eecr value.

Stefan Rueger d05ddd188d Fix usbtiny read/verify for parts with more than 64 kB flash
Usbtiny has a protocol or firmware problem that prevents it from reading
flash above 64 kB in page mode (used by -U flash:r:... and -U flash✌️...).
This commit fixes that problem by falling back on byte access for flash paged
reads above 64k. It also issues the correct load extended address command for
parts with more than 128 kB flash thus extending support to ATmega2560 et al.

Add direct SPI mode to USBtiny
It is limited to exactly sending (and receiving) multiples of 4 bytes,
and unlike programming mode where slave select isn't required, SS must
be held low for SPI to work. USBtiny programmers don't usually have
a wire for SS.
