- fixed ANSI (C89) issues, including #418

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.

 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

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)).

[../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.

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

 Turn on -Wconversion in Makefile, fix all warnings

 There was already some space reserved as a guard, added check for writes
 before the beginning of the buffer. Did not change the 'overrun' message.
 Underrun buffer writes are likely to be a more rare case.

 This feature removes the dependency on malloc/free for constrained
  embedded systems without a heap. It uses a static heap inside
  Unity Fixture. Setting UNITY_INTERNAL_HEAP_SIZE_BYTES sizes the heap.
 Add tests for new option, add targets to makefile for running tests.
 UNITY_FIXTURE_MALLOC for Fixture use only, remove from unity_output_Spy.c.

 Help failures in the spy by adding filename and message to output

 Add CFLAGS in Fixture Makefile to catch C99 rules with '-pedantic'

 Ignore tests that need the Spy if we are not building with it

 Don't set CurrentTestFailed = 0 at end, move before last check
 These tests now fail if the output_Spy is not used instead of putchar()

 Revert part of commit 77af37ad, code looked like a temporary change
 The behavior is back to the original, printing "....!..." in quiet mode
 Added an ignored test to Fixture for visual inspection

At the start of unity_free(), check mem for NULL, and return immediately
if it is, so we don't crash in this case. This mimics the behaviour of
most free() implementations. Closes #135.

Primarily -
* Added "static" to static functions.
* Added proper signature with "void" to functions without arguments.
* Marked unused arguments with "(void)".
* Removed entirely unused static functions.
* Added "const" to preserve const-correctness.
* Added function prototypes for external functions.

updating CLI for unity_fixture.h to handle unknown command line arguments (instead of entering an infinite loop)

     Likewise, place all function prototypes before statements.
     These changes support Microsoft Visual Studio 2008 Express Edition,
       which follows C89-style rules.

- fixed a few bugs in fixtures to get it to pass against our standard compilers
- added extern of OUTPUT_CHAR method to keep compilers from complaining
