Config file support for clang-format, part 2.
Summary:
Adds actual config file reading to the clang-format utility.
Configuration file name is .clang-format. It is looked up for each input file
in its parent directories starting from immediate one. First found .clang-format
file is used. When using standard input, .clang-format is searched starting from
the current directory.
Added -dump-config option to easily create configuration files.
