Static checker updates

naming checker: Also exclude *ReflexDict.cxx files from naming checks.

usingns checker: Add boost/bind.hpp as an exception.

thread checker: Fix test for a const array. Const static objects are ok, but we weren't properly recognizing a const array because the qualifier information is in the element type node, not that of the array itself. Fixed.

Exclude some ROOT functions from the threading unchecked function warning.
