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
