fallback syntax used when we fail to find a '.clang-format' file. Adjust
variable names appropriately.

Update the editor integration pieces that specify a '-style' option to
specify it as '-style=file'. I left the functionality in place because
even if the preferred method is to use '.clang-format' files, this way
if someone needs to clobber the style in their editor we show how to do
so in these examples.

Also check in a '.clang-format' file for Clang to ensure that separate
checkouts and builds of Clang from LLVM can still get the nice
formatting. =] This unfortunately required nuking the test for the
absence of a '.clang-format' file as now the directory happening to be
under your clang source tree will cause there to always be a file. ;]

Added -lines X:Y option to specify line range to process. This is a more human-friendly alternative to -offset and -length.

This fixes llvm.org/PR16514.

llvm-svn: 185531

Summary:
Some valid pre-C++11 constructs change meaning when lexed in C++11
mode, e.g.
#define x(_a) printf("foo"_a);
(example from http://llvm.org/bugs/show_bug.cgi?id=16342). "foo"_a is treated as
a user-defined string literal when parsed in C++11 mode.
In order to deal with this correctly, we need to set lexing mode according to
which standard the code conforms to. We already have a configuration value for
this (FormatStyle.Standard), which seems to be appropriate to use in this case
as well.

With this patch, clang-format will try to keep the cursor at the
original code position in editor integrations (implemented for emacs and
vim). This means, after formatting, clang-format will try to keep the
cursor on the same character of the same token.

Summary: + improved handling of default style and predefined styles.

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.

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.
