shiboken2: Add file location to more warnings

Output most warnings in the standard file:line syntax
used by compilers. This is done for C++ source code
and typesystem files.

Introduce a class SourceLocation and add it to type entry,
AbstractMetaFunction and AbstractMetaClass.
Move more messages into messages.cpp and output the location.

Change the errors reported by the XML typesystem parser to
the same format.

[ChangeLog][shiboken] A number of error and warning messages have
been prefixed by file name and line for better tooling.
