Redefine qh_exit() as 'throw std::runtime_error("QH10003 ...")'

This file is not included in the Qhull builds.

qhull_r calls qh_exit() when qh_errexit() is not available. For example,
11
it calls qh_exit() if you linked the wrong qhull library.
12
13
The C++ interface avoids most of the calls to qh_exit().
14
15
If needed, include usermem_r-cpp.o before libqhullstatic_r.a. You may need to
16
override duplicate symbol errors (e.g. /FORCE:MULTIPLE for DevStudio). It
17
may produce a warning about throwing an error from C code.
