Fix docs.

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.

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

Macros TEST_ASSERT_LESS_OR_EQUAL_HEX32_MESSAGE() and TEST_ASSERT_LESS_OR_EQUAL_HEX64_MESSAGE() need to be mapped to UNITY_TEST_ASSERT_SMALLER_OR_EQUAL_HEXnn() instead of UNITY_TEST_ASSERT_SMALLER_THAN_HEXnn()

 Make all comparison operators on integers available

This is simpler and more flexible than embedding C code in the Ruby options
(:suite_setup and :suite_teardown).  However, support for :suite_setup and
:suite_teardown is kept for backwards compatibility.

Several configurations are possible:
1. :suite_setup and :suite_teardown options provided and used.
2. :suite_setup and :suite_teardown options not provided (nil):
  2a. Weak symbols not supported; suiteSetUp() and suiteTearDown() are not called.
      It would be simpler to make user-provided functions mandatory in this case,
      but it could break some pre-existing test suites.
  2b. Weak symbols are supported and the stub implementations of suiteSetUp() and
      suiteTearDown() are called if there are no user-provided functions.
  2c. Weak symbols are supported but overridden by user-provided suiteSetUp() and
      suiteTearDown() functions.

The setjmp calls are all in TEST_PROTECT() already

Revised internal type naming scheme to better sandbox Unity away from everything else. Sure, short was nice, but not at the expense of naming collisions.

Remove UNITY_FLOAT_VERBOSE entirely, add option UNITY_EXCLUDE_FLOAT_PRINT
Remove some questionable float casts from doubles
Default to Round Ties to Even behavior, add option to Round Ties Away from Zero

 Add test for failure count and UnityEnd return value
 Cover printing escape codes with length parameter
 Full statement coverage

 For easier automation and searching for a test suite failure

With a buffer long enough, no truncation should be neccesary to format floats.

Buffer length is user settable by defining UNITY_VERBOSE_NUMBER_MAX_LENGTH,
otherwise a sensible default is used based on desired precision.

 Now that the project is using .gitattributes, get rid of CRLF in the repo.

Added parentheses around all macro parameters to resolve MISRA 2004
rule 19.10, "in the definition of a function-like macro, each instance
of a parameter shall be enclosed in parenthesis" as tested with the
IAR EW for 8051 compiler, version 9.20.2.

The only questionable change is in "unity_fixture.h" where the nested
macro DECLARE_TEST_CASE in RUN_TEST_CASE prevents surrounding params
"group" and "name" with parentheses.
However, it appears that macro DECLARE_TEST_CASE isn't used elsewhere,
so I eliminated DECLARE_TEST_CASE and put its expansion directly in
RUN_TEST_CASE.  Now the following header files pass rule 19.10:
* unity.h
* unity_internals.h
* unity_fixture.h

For my own project, this change to the Unity test framework allows me
to include my unit test code to be tested against MISRA rules as well,
instead of just production code, to help enforce style and team
guidelines.
