Make sure the malloc alignment is always aligned to the architecture's pointer size

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.

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

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/src/unity_fixture.c:210]: (error) Memory leak: guard

Found by https://github.com/bryongloden/cppcheck

 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.

 Using gcc 4.8 on Ubuntu 14

 Turn on -Wconversion in Makefile, fix all warnings

 These wrapper functions should be in Unity core if warranted.
 Use the Unity struct directly for access, or consider macro functions

 The old failure would print the line in unity_fixture.c, not very useful.
 Now using CurrentTestLineNumber, which is better.

 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.

 Consistent use of one-liners and NULL

 For redefinition of UNITY_FIXTURE_MALLOC/...FREE use both or replace both.
 Clean up whitespace, remaining void*, and comment.

 Delete unused variables and empty functions
 Make setUp & tearDown (used in Unity core) optionally defined
  if 'weak' linking is present

 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

 Using sizeof() instead of constant 4, makes code less fragile to change
 Change name of 'guard' in Guard struct to 'guard_space'

- Cleaned up a casting warning error
- Removed a couple semicolons from the end of macros SHAME!

This helps clarity and is more obvious, it looks like a print function

Delete the { ;} braces and semicolon from UNITY_PRINT_EOL to give it expected
  behavior: 1) requires a semicolon 2) works in one-liner if-else statements
If you need "\r\n" for EOL, define as the following to get the same behavior:
  do{UNITY_OUTPUT_CHAR('\r'); UNITY_OUTPUT_CHAR('\n');}while(0)

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.

Ignored tests are now correctly skipped if not selected by test name or
by group name.

Fixes #116: Allow overrides of the Unity Fixture's memory functions. This enables custom heap implementations to be used with the Unity Fixture.
