34272657de clang-format: Format extern "C" blocks like namespace blocks. 
namespace blocks act as if KeepEmptyLinesAtTheStartOfBlocks is always true,
and aren't collapsed to a single line even if they would fit. Do the same
for extern "C" blocks.

Before,

  extern "C" {

  void ExternCFunction();

  }

was collapsed into `extern "C" { void ExternCFunction(); }`. Now it stays like
it was.

Fixes http://crbug.com/432640 and part of PR21419.

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.
