By passing --omit_begin_end=1 to generate_test_runner.rb, the script
will now omit calls to UnityBegin and UnityEnd when running tests in a
suite.

This allows multiple suites to be executed in a row, and then have an overall
summary of the tests which were executed across all suites.

- fixed ANSI (C89) issues, including #418

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

- Tweak a couple style problems with Ruby scripts.

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.

Used sizeof() operator for pointer increments and substituted sizeof() operator for the unsigned int mask calculation to "UNITY_INT_WIDTH / 8" in function "UnityAssertEqualIntArray".

Fixed maximum number of nibbles for processor where sizeof() operator doesn't return the size of a type in 8-bit bytes (e.g. the TI C2000 series).

- Running time macros have been made more portable, previously it was not
  possible to override all macros
- Running time macros will be executed by default test runner, and auto test
  runners
- Adds a default execution time implementation for unix. (Previous default
  implementation only worked on Windows)
- For embedded platforms there is a simple method of getting a default
  implementation by defining a single macro UNITY_CLOCK_MS()
- Removed need for UNITY_EXEC_TIME_RESET. This was not being used for the default
  implementations, if anything ever did need reset-like functionality it could
  simply be wrapped up with the start or stop macros for that platform

Macro UNITY_EXCLUDE_PRINT_FORMATTED changed to UNITY_INCLUDE_PRINT_FORMATTED.
Enable printf via "-DUNITY_INCLUDE_PRINT_FORMATTED" compiler option.

Added include of 'stddef.h' to 'unity_internals.h' if 'UNITY_EXCLUDE_STDDEF_H' is not defined. This adds compiler independent support for the 'NULL' macro.

MISRA 2004 rule 19.10: inside macros, surround each parameter usage with parentheses.

parameter names should match between declaration and definition.
(MISRA 2004 rule 16.4)

- Enable support for Green Hills Software compiler
- Define weak implementations only once except on Windows

 Make all comparison operators on integers available

 Check for unsigned types, add 'or equal to' support
 Consolidate to one function to remove repeated code

The user can specify UNITY_OUTPUT_CHAR_HEADER_DECLARATION and
UNITY_OUTPUT_FLUSH_HEADER_DECLARATION when he would like to declare
UNITY_OUTPUT_CHAT or UNITY_OUTPUT_FLUSH respectivly

Fixed copy-paste error for:
- UNITY_TEST_ASSERT_EACH_EQUAL_INT64
- UNITY_TEST_ASSERT_EACH_EQUAL_UINT64
- UNITY_TEST_ASSERT_EACH_EQUAL_HEX64

So that the comparison is done on the expected _value_ instead of the _array_.
