parameter names should match between declaration and definition.

- Fixed some style issues.

Starting to enforce our coding style. The first step is that we’ve pulled in Rubocop to check out Ruby syntax. There is likely a bit of customization to do yet AND there is definitely that backlog of todo’s that we just told it to ignore.

Used clang-format, which produces noise on stuff you don't care about
and requires setting it up to match the existing code base. Kept the
potentially useful changes, discarded the rest, some manual tweaking
required. It did catch lots of pesky indentation mistakes.

Remove UNITY_FIXTURES option, which was probably not doing what was
originally indended. It was suppressing the test name even in quiet mode.

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.

Mangling issues, as always.

 Remove stdint.h from the C89 build due to -pedantic warnings from type
  'long long' and constants like UINTPTR_MAX = 18446744073709551615ULL

 Make it more clear that each test of the internal heap implementation
  should free in LIFO order. Without this check, memory can be stranded
  but still pass.

 The internal malloc must free in LIFO order

 This reverts commit 783fcaea
 The guard memory bytes should never be freed inside unity_malloc()

I believe if realloc() returns a pointer to a different location, the old location is freed. However, the pointer 'n1' is not freed if realloc fails to obtain a large enough block of memory and returns NULL. (more details on [StackOverflow](http://stackoverflow.com/a/16676964)).

Sorry @mvandervoord -- not your code, your repository 😁

Regarding the double free, cppcheck has a check for that too (just saying) 👍

Free guard if UNITY_EXCLUDE_STDLIB_MALLOC is not defined. 👍

Thanks @ for the hint.

[../Unity-master/extras/fixture/test/unity_fixture_Test.c:530]: (error) Deallocating a deallocated pointer: n1

This solution from Daniel Fischer was helpful in fixing the error because if realloc returns a pointer to a different location, the old location is freed.

 Add tests for uncovered lines

 Add extern UnityFixture in internals header. Add C89 target in Makefile
 clang will show these warnings but can suppress "//" with -Wno-comment.

 By removing the call to the Conclude function the code is simplified
  and doesn't depend on global state updates. Tests that are ignored
  after the testBody is called still output the right EOL.

 This fixes #168. See that github.com issue for more discussion.
 Allows the tests to build when putchar() is defined as a macro
  with parenthesis around it, as in the ARM embedded gcc compiler.

 Using gcc 4.8 on Ubuntu 14

 Gets rid of warnings about extern with clang's -Weverything
