Cleaned up compiler flags in root meson.build, renamed a variable and removed 'c_std=<standard version>' because Meson sets C standard flag to C11 by default.

Get the 2's compliment of the unsigned int `number` when printing results without relying on problematic recasting of a negated int. (see #439)

optimisation(AVR): Store static string in AVR EEPROM

* This can save a lot of program memory and allow to run test on ATTiny

Quick fix to Meson example.

Add TEST_MESSAGE for outputting messages without aborting a test and _MESSAGE variant to TEST_PASS collection.

TI C55x compatibility patches - removal of sizeof operator from the interfaces

Meson support for Unity unit testing framework.

- Tweak a couple style problems with Ruby scripts.

add a blank line after #include "unity.h"

The include must be in the first line, else you may expect some issues.
Some autoformat tools could sort the includes alphabetically and could
break the test.

Introduce patch from "UnityAssertEqualIntArray" for "UnityAssertNumbersArrayWithin" in order to get rid of the sizeof() operator

sizeof() is a hell of an operator and returns the size of a data type in terms of "addressable units" which is not necessarily the size in bytes. To circumvent this problem and in order to keep the API clean we try to remove all sizeof() from the API.

silent mode in unity fixture

Added .editorconfig in order to set editors to the right settings.
