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.

This is just a slight improvement for the fix in r181299, which fixes
formatting the very last line of a file.

llvm-svn: 181303

Emacs seems to have a line that is just past the last character of the
buffers content. This needs to be handled specially so that clang-format
is not called with an invalid -offset.

This patch ensure that nothing scrolls even if the same buffer is opened
in multiple windows.

llvm-svn: 180252

Summary:
Added support for multiple input files, that can be used both with and
without in-place edit (-i) option. Added checks for -offset and -length options:
don't allow them on multiple files, check that they don't fall outside input
file, made both options unsigned, so that there's no need to check for negative
values. Removed "-1 can be used for end-of-file" from -length description.

The new emacs integration is simpler, does not save the current file
before reformatting and ensures that emacs does not scroll as a result
of formatting.

Also explicitly set the style in clang-format tests to make them more
robust.

llvm-svn: 179372

This adds an emacs editor integration (thanks to Ami Fischman). Also
pulls out the style into a variable for the vi integration and just
uses clang-formats defaults style in clang-format-diff.py.

The styles are now documented with the -style option. This fixes
llvm.org/PR15689.
