Summary: Fix for  #221791 (bad \x escape)

Initial Comment:
This patch adds file and line output if a bad \x escape
was found in the source. It does so with the following
modifications:

- PyErr_Display now recognizes syntax errors not by
their class, but by an attribute print_file_and_line
- this attribute is set for all SyntaxError instances
- PyErr_SyntaxLocation is enhanced to set all attributes
expected for a syntax error, even if the current
exception has a different class.
- compile.c now invokes PyErr_SyntaxLocation for all
non-syntax exceptions also, mostly through com_error.

If the pydebug problem can be fixed, I'd be all for
implementing it, and adding to 2.2.1.

This doesn't compile --with-pydebug (he suddenly notices).

There's an assert(val == NULL) in compile.c, but no variable
val.
