update checkpatch.pl to version 0.19



This version is a bit of a whopper.  This version brings a few new checks,
improvements to a number of checks mostly through modifications to the
way types are parsed, several fixes to quote/comment handling, as well as
the usual slew of fixes for false positives.

Of note:
 - return is not a function and is now reported,
 - preprocessor directive detection is loosened to match C99 standard,
 - we now intuit new type modifiers, and
 - comment handling is much improved

Andy Whitcroft (18):
      Version: 0.19
      fix up a couple of missing newlines in reports
      colon to parenthesis spacing varies on asm
      values: #include is a preprocessor statement
      quotes: fix single character quotes at line end
      add typedef exception for the non-pointer "function types"
      kerneldoc parameters must be on one line, relax line length
      types: word boundary is not always required
      improved #define bracketing reports
      uninitialized_var is an annotation not a function name
      possible types: add possible modifier handling
      possible types: fastcall is a type modifier
      types: unsigned is not a modifier on all types
      static/external initialisation to zero should allow modifiers
      checkpatch: fix recognition of preprocessor directives -- part 2
      comments: fix inter-hunk comment tracking
      return is not a function
      do not report include/asm/foo.h use in include/linux/foo.h
      return is not a function -- tighten test
