Add format example to minetest.conf.example
Add Settings::setU16()
Throw exception on attempted access of NULL settings groups

Without this patch node 0,0,0 is highlighted when enable_node_highligting is false
There is a minor lighting issue remaining, however it seems to be related to a different bug (https://github.com/minetest/minetest/issues/1887)

Note: this does not fix the warnings generated by clang

The ratios between the sizes of form elements, including text, is now
fixed, aside from variations caused by rounding.  This makes form layout
almost fully predictable, and particularly independent of player's
screen size.  The proportions of non-text elements are the traditional
proportions.

For compatibility, the way in which element positions and sizes are
specified remains unchanged, in all its baroqueness, with one exception.
The exception is that the position of a label[] element is now defined
in terms of the vertically center of the first line of the label,
rather than the bottom of the first line of the label.  This change
allows a label to be precisely aligned with button text or an edit box,
which are positioned in a centering manner.  Label positioning remains
consistent with the previous system, just more precisely defined.

Make multi-line label[] elements work properly.  Previously the code set
a bounding rectangle assuming that there would be only a single line,
and as a result a multi-line label would be cut somewhere in the middle
of the second line.  Now multi-line labels not only work, but have
guaranteed line spacing relative to inventory slots, to aid alignment.

Incidentally fix tabheader[] elements which were being constrained to
the wrong width.

Given an unusually large form, in variable-size mode, the form rendering
system now chooses a scale that will fit the entire form on the screen,
if that doesn't make elements too small.  Fixed-size forms, including the
main menu, are have their sizes fixed in inch terms.  The fixed size for
fixed-size forms and the preferred and minimum sizes for variable-size
forms all scale according to the gui_scaling parameter.

Changes:
  * Add extra documentation for remove_item.

    This isn't as silly as it sounds: iterate a list containing items with
    unique metadata each, and remove_item the first one you find, placing
    into a different - fine, except the remove will invariably remove the
    wrong one, leading to items being duplicated and others destroyed.

    Arguably it's a bug, and Inventory::removeItem should actually remove
    the item you tell it to. (i.e. if the passed ItemStack has metadata,
    match it). But it seems reasonable to just document the behaviour
    more clearly.

 * Improve string_to_pos documentation.
 * Clarify dig_node documentation (return value).
 * Better on_step documentation.
 * get_nodemeta -> get_meta.
 * Other minor fixes.

This is not optimal as it will cause minor graphical glitches for
Irrlicht 1.7 users, but at least it fixes the build.

According to doc/lua_api.txt if paramtype2 == "facedir" the two least significant bits of parm2 orient the texture around the axis. For dirs1 (looking at a wall) these would be 0, 1, 2, 3 and for dirs2 (looking at the ceiling) 2, 1, 0, 3

f7d65091 introduces error when no endian.h found in the system.

Since "CHECK_INCLUDE_FILE" returns empty string instead of "0", when
"cmake_config.h" is generated it has "#define CMAKE_HAVE_ENDIAN_H " line.
Later we have "#define HAVE_ENDIAN_H CMAKE_HAVE_ENDIAN_H" in the
"config.h", an thus "HAVE_ENDIAN_H" is also empty sting. Because of
this, "#if HAVE_ENDIAN_H" is incorrect preprocessor directive.

serialize.h: use machine native byte swapping if available, fall-back to previous generic method if not (supported for GCC using endian.h, detection done in cmake) write/readARGB8() - just write 32-bit color in one op, instead of 4 1-byte ops cleanup: removed unneeded buffer init for some serialize-out functions use a #define for the fixed point factor in read/writeF1000()
