  Split p_strlen into its own header
  
  We need this from util.h and posix.h, but the latter includes common.h
  which includes util.h, which means p_strlen is not defined by the time
  we get to git__strndup().
  
  Split the definition on p_strlen() off into its own header so we can use
  it in util.h.
