540dbe29bc clang-format: Prevent column layout if elements aren't uniform enough.

650ecb53ca Fix bug 20892 - clang-format does not handle C-style comments
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20892

Add support of C-style formatting enabling/disabling directives. Now the following two styles are supported:

  // clang-format on
  /* clang-format on */

The flexibility in comments (support of extra spaces and/or slashes, etc.) is deliberately avoided to simplify search in large code bases.

a043cedf0a Fixes bug 20587 - Add K&R break before braces style
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20587

Added K&R style. It could be enabled by the following option:

```
BreakBeforeBraces: KernighanRitchie
```

This style is like `Attach`, but break *only* before function
declarations.

As I can see, no additional logic required to support this style, any
style different from other styles automagically satisfies K&R.

The posix errno values are probably to the best thing to use for
describing parse errors.
