7bb326d389 eeprom: provide smaller code for SERIAL_ECHOPAIR
SERIAL_ECHOPAIR implies, eventually, two calls to MYSERIAL.print.  One
of these has FORCE_INLINE for a per-character loop, and both involve
constructing a method call rather than a simple function call.

Produce better and smaller code by providing three specialised
functions serial_echopair.  This saves 672 bytes of program memory
(with EEPROM_SETTINGS and SDSUPPORT enabled).

957e966d2d M206: always use homing ("homeing") offsets
Previously the parameters set in M206 would only be used if a G82
command was sent with specific axis home values.  This limits its
usefulness.

Really, we should have a way to adjust the XYZ homing of a machine in
the eeprom.  So as the first stage of this, make M206 affect every
home command.  The values set using M206 are now added to the
configuration variables [XYZ]_HOME_POS.

This is achieved by replacing all uses of [XYZ]_HOME_POS in the code
by a new home_pos[] which includes the adjustment.  We also have to
adjust the uses of [XYZ]_{MIN,MAX}_POS similarly - see below.


To allow axis_is_at_home to be written as a function taking an axis
index rather than a macro taking an axis letter, we provide
constant arrays in program memory containing the values of
[XYZ]_{MIN,MAX,HOME}_POS from the compiled-in configuration.

This is done with some helper macros to deal with the declaration
(XYZ_CONSTS_FROM_CONFIG) and definition of the inline function which
does the program memory access.

We also introduce the overloaded function read_pgm_any, whose
instances are produced with DEFINE_PGM_READ_ANY, which allows the
access functions to automatically produce the correct type.

The type- and pointer-massaging code in the access function boils
down, when compiled, to a simple program memory access.


A question arises: if the M206 offset is set, should this adjustment
to the home position shift or change the possible range of movement
permitted by the software endstops ?

The documentation in Configuration.h describes these limits as:
    // Travel limits after homing
Since this is a file containing physical limits, and actual suggested
values for these configuration parameters appear to include a certain
amount of slop, I've taken the view that these should be regarded as
nominal physical distances from the limit switches, and that the
permissible travel should be unaffected by M206.

So for example with the (rather unrealistic)
  #define X_HOME_DIR -1
  #define X_MIN_POS -20
  #define X_HOME_POS 0
  #define X_MAX_POS 100
no matter the setting of M206 X, the machine would be permitted
to move from 20mm "beyond" the limit switch trigger point in
the negative X direction and 100mm away from the limit switch in
the positive X direction, for a total travel of 120mm.

With M206 X-10 that would be considered to correspond to X coordinates
-30 to +90.  With M206 X+10 that would be considered to correspond to
X coordinates -10 to +110.


fixes #200 (in ErikZalm/Marlin).

faccb35850 software_endstops: use *_MIN_POS and *_MAX_POS for arcs
If [XYZ]_HOME_POS and [XYZ]_MIN_POS aren't 0, these corrections are
wrong.  Use the same logic as in Marlin.pde:prepare_move: ie, clamp to
[XYZ]_{MIN,MAX}_POS.

While we're here, put this cut-and-paste code in a function
clamp_to_software_endstops.

3f15b7c7b8 Makefile: Better display of size (device memory usage)
Run avr-size with the --mcu=... -C option as well.  That reports how
much actual device program and data memory is used along with a
percentage fullness.

0c35facc94 Makefile: support V=1
Often it can be useful to see the actual commands being run by make.
Other projects (eg, the Linux kernel) support this with a "V=1" make
parameter.  Do the same here.

538189cc19 Fixed soft limits when the origin is in the middle.
HOME_POS is now always where the endstop is and can be outside the limits.
The limits are now defined by MIN_POS and MAX_POS rather than HOME_POS and MAX_LENGTH.
The Z is axis now homed first if direction is away from the bed.

Saguinololu limit pins change from MIN to MAX according to the homing direction.
