Clean up bookmark related codes.
Remove CPDF_Dictionary*() operator in CPDF_Bookmark class. Unify naming conventions and coding styles. Change some functions to const. Change the name of function argument to |pDict| for FPDF_xxx type variable. This makes the code more clear and gives better variable naming R=tsepez@chromium.org Review URL: https://codereview.chromium.org/828203002
