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`.

9e32199861 Do not force linebreaks when MaxEmptyLinesToKeep is 0.
Previously we would format
 call(

as
 call(
     p);
with MaxEmptyLinesToKeep == 0.

Now we format it as:
  call(p);

a5fa4d1d7e clang-format: Fix __attribute__ being treated as decl name.
__attribute__ was treated as the name of a function definition, with the
tokens in parentheses being the parameter list. This formats incorrectly

__attribute__ like decltype.

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

fixed amount of spaces from the start of the line. Don't do this in
