788ffd71c6 clang-format: Always allow break after leading annotations.
Before:
  DEPRECATED("Use NewClass::NewFunction instead.") int OldFunction(
  const string &parameter) {}

Could not be formatted at all, as clang-format would both require and
disallow the break before "int".

100ffc632a clang-format: Be more conservative about specially indenting blocks in C++.
This is a bit of a step back of what we did in r222531, as there are
some corner cases in C++, where this kind of formatting is really bad.

Example:
Before:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant = [&]() {
    return true;
  }, aaaaa aaaaaaaaa);

After:
  virtual aaaaaaaaaaaaaaaa(std::function<bool()> IsKindWeWant =
                               [&]() { return true; },
                           aaaaa aaaaaaaaa);

The block formatting logic in JavaScript will probably go some other changes,
too, and we'll potentially be able to make the rules more consistent again. For
now, this seems to be the best approach for C++.

291f64fd03 Add WebKit brace style configuration option.
Summary:
Add brace style `BS_WebKit` as described on https://www.webkit.org/coding/coding-style.html:

* Function definitions: place each brace on its own line.
* Other braces: place the open brace on the line preceding the code block; place the close brace on its own line.

Set brace style used in `getWebKitStyle()` to the newly added `BS_WebKit`.

b001a0ba5e clang-format: Add MacroBlock{Begin,End} options
The MacroBlockBegin and MacroBlockEnd options make matching macro identifiers
behave like '{' and '}', respectively, in terms of indentation.

Mozilla code, for example, uses several macros that begin and end a scope.
Previously, Clang-Format removed the indentation resulting in:

    MACRO_BEGIN(...)
    MACRO_ENTRY(...)
    MACRO_ENTRY(...)
    MACRO_END

Now, using the options

    MacroBlockBegin: "^[A-Z_]+_BEGIN$"
    MacroBlockEnd: "^[A-Z_]+_END$"

will yield the expected result:

    MACRO_BEGIN(...)
      MACRO_ENTRY(...)
      MACRO_ENTRY(...)
    MACRO_END
