try not to write absolute source file paths into C file position comments and use paths relative to build directory instead

allow subtypes in right operand to override left side parent class behaviour for "@" operator (Python tries "__rmatmul__()" first in this case), generally clean up code duplication while at it

make libcython.py Py2/3 compatible to allows its immediate usage from both versions (and clean it up a little)

reduce excessive inlining in calling code a bit by moving some fallback code into a non-inline function

allow useless trailing semicolons in some places where people tend to put them, but warn about them (trac ticket 832)

Get rid of obsolete Python cruft

avoid useless indirection during CFunction setup and instead use known module dict reference directly

* Remove macros __Pyx_{NAME|DOC}STR
* Remove macros __Pyx_{Get|Set|Del}AttrString
* Remove macro  __Pyx_PyIndex_Check
* Remove workaround for missing BaseException in builtins

move JediTyper into Tools directory as it's not in a state that would suggest making it a part of Cython
