Before AllowShortFunctionsOnASingleLine could either be true, merging
all functions, or false, merging no functions. This patch adds a third
value "Inline", which can be used to only merge short functions defined
inline in a class, i.e.:
void f() {
return 42;
}
class C {
void f() { return 42; }
};

init list formatting. This suggestion has now gone into the LLVM coding
standards, and is particularly relevant now that we're using C++11.
Updated a really ridiculous number of tests to reflect this change.

Mozilla and WebKit seem to use a space after @property (verified by
grepping their codebases) so we turn this on there as well.

Unexpectedly, it seems that people commonly know what they were doing
when writing a comment.
Also, being more conservative about comment breaking has the advantage
of giving more flexibility. If a linebreak within the comment can
improve formatting, the author can add it (after which clang-format
won't undo it). There is no way to override clang-format's behavior if
it breaks a comment.

Formatting this:
void f() { // 1 space initial indent.
int i;
#define A \
int i; \
int j;
int k; // Format this line.
}
void f() {
#define A 1 // Format this line.
}
Before:
void f() { // 1 space initial indent.
int i;
#define A \
int i; \
int j;
int k; // Format this line.
}
void f() {
#define A 1 // Format this line.
}
After:
void f() { // 1 space initial indent.
int i;
#define A \
int i; \
int j;
int k; // Format this line.
}
void f() {
#define A 1 // Format this line.
}

BreakConstructorInitializersBeforeComma is true.
This option is used in WebKit style, so this also ensures initializer lists are
not put on a single line, as per the WebKit coding guidelines.

Added BraceBreakingStyle::BS_GNU. I'm not sure about the correctness of
static initializer formatting, but compound statements should be fine.

Summary:
Allow predefined styles to define different options for different
languages so that one can run:
clang-format -style=google file1.cpp file2.js
or use a single .clang-format file with "BasedOnStyle: Google" for both c++ and
JS files.
Added Google style for JavaScript with "BreakBeforeTernaryOperators" set to
false.

Summary:
The rule from the GNU style states:
"We find it easier to read a program when it has spaces before the open-parentheses and after the commas."
http://www.gnu.org/prep/standards/standards.html#index-spaces-before-open_002dparen
This patch makes clang-format adds an option to put spaces before almost all open parentheses, except the cases, where different behavior is dictated by the style rules or language syntax:
* preprocessor:
** function-like macro definitions can't have a space between the macro name and the parenthesis;
** `#if defined(...)` can have a space, but it seems, that it's more frequently used without a space in GCC, for example;
* never add spaces after unary operators;
* adding spaces between two opening parentheses is controlled with the `SpacesInParentheses` option;
* never add spaces between `[` and `(` (there's no option yet).

Previously, clang-format could create quite corrupt formattings if
individual lines of nested blocks (e.g. in "DEBUG({})" or lambdas) were
used. With this patch, it tries to extend the formatted regions to leave
around some reasonable format without always formatting the entire
surrounding statement.

No functional changes intended. However, it seems to have found a buggy
behavior in one of the tests. I think this structure is generally
desirable and it will make a planned bugfix significantly easier.

Before, clang-format would always format entire nested blocks, which
can be unwanted e.g. for long DEBUG({...}) statements. Also
clang-format would not allow to merge lines in nested blocks (e.g. to
put "if (a) return;" on one line in Google style).
This is the first step of several refactorings mostly focussing on the
additional functionality (by reusing the "format many lines" code to
format the children of a nested block). The next steps are:
* Pull out the line merging into its own class.
* Seperate the formatting of many lines from the formatting of a single
line (and the analysis of the solution space).
