Converting libqhull to libqhullr 2014

===============
Keep libqhull as is.  It is needed for compatibility with existing code, both w/ w/o qh_QHpointer.
The 'qh' macro cannot be replaced with 'qh.'

==============
Steps to update C code to reentrant qhull (e.g., testqset_r.c, user_eg*.c)

Branch the code to ..._r.c

Rename include files
#include "qhull_ar.h"

Allocate qh at the top, and remove other references to qh_qh and qh_qhPOINTER
  qhT qh_qh;
  qhT *qh= &qh_qh;

If needed, remove spaces between name and argument list
  {[^a-zA-Z0-9_][a-zA-Z0-9_]*} \(
  \1(
  
Make the following regexp substitions [DevStudio uses {} for grouping instead of ()]

  Prefix function declarations with "(qhT *qh, "
  ^{[a-zA-Z0-9]* [a-zA-Z0-9]*\}(
  \1(qhT *qh, 

  'qh' is the first argument for most internal calls and qhull calls
  \({[a-zA-Z0-9_]*, }
  (qh, \1
  
  \({[a-zA-Z0-9_]+}\)
  (qh, \1)
  
  \(\)
  (qh)

  'qh '
  'qh->'
  
Other substitions to consider

  ("
  (qh, "
  
  (&
  (qh, &
  
  ()
  (qh)

Review the code for obvious errors
Remove qhT for functions that do not need it

Make the following substitions to correct mistakes made above
  qh, qh,
  qh, 

  qh, void
  qh
Review the code for routines that do not take qh

Compile and fix the errors

==============
Steps

Build qhullr.sln from qhull_all.sln
  Shadow build isn't working for header files. libbqhull and libqhullr
   RelativePath="..\..\src\libqhull\
  Doesn't create qhullstatic_rd.lib
  
  include only libqhullstaticr and qhullr
  remove libqhull, libqhullp, libqhullr to avoid double searches
  remove all but testqset from testqset
  
Replace all include files with _r.h

[qhull_all] Remove all spaces before the parens 'qh_... (...)' 

Checked in source

Check for access to .c and .h files

Add qhmemT *qh before all routines
   # Routines with arguments, 3648+498 occurrences
   {qh_[a-zA-Z0-9_]*[^_]\(}{[^)/]}
   \1qhmemT *qh, \2

   # Routines with comment args, 15+ occurrences
   {qh_[a-zA-Z0-9_]*[^_]\(}{[/]}
   \1qhmemT *qh \2
   
Exceptions 104+55 instances
  qhmemT *qh, void
  qhmemT *qh

  # times
  SETtruncate_(qhmemT *qh, 
  _(
  
  qhmemT *qh, qhmemT *qh,
  qhmemT *qh,

  qhmemT *qh, qhmemT *qh
  qhmemT *qh

In C code
  ^{  *qh_.*}qhmemT *qh
  \1qh

  # 602 occurrences, needs repeat  
  ^{ .*}qhmemT *qh
  \1qh
 
  # 3746 occurrences
  {[^a-z]}qh {[a-zA-Z]}
  \1qh->\2

All files, 891 occurrences
  qhmemT \*qh{[^a-zA-Z]}
  qhT *qh\1

  qhT *qh *
  qhT *qh, void *
  
  qhmem.
  qh->qhmem.
  
  # 99 occurrences
  qhstat 
  qh->qhstat.
  
Removed rboxT from rboxlib_r.c

1138 errors and 438 warnings.

Remove dependency on libqhull_r for statT
Convert FOREACHsetelement_i_ in libqhull_r.h 
traceN needs qh for qh_fprintf
add qh to () calls

Down to 600 errors

Reorganized projects for cpp. 

Fixed up qhull_p-exports.def.  qhull_r-exports.def has no DATA records.

user_eg3 with libqhullpcpp worked correctly the first time

IISPY-/local/qhull/bin>   user_eg3 rbox "100000 t100 s"  qhull
rbox 100000 t100 s
