sb118: #i108776# changed addsym.awk to also export STLport num_put symbols, and simplified it by requiring that first section is labeled UDK_3_0_0; adapted map files accordingly, replacing many individual ones with solenv/src templates

sb118: changed tools/debug to never fall back from writing to shell to writing to file, and read DBGSV_INIT from rtl::Bootstrap; the latter causes problems if tools/debug is called from static code executing before SAL_MAIN has called osl_setCommandArgs -> removed statics from code and added assertions to osl/process; various improvements to smoketests.cxx (incl. passing an appropriate dbgsv.ini for non-pro builds)

sb118: #i108324# deprecated osl/semaphor.h etc., as it is unsupported on Mac OS X and unused, anyway

sb118: allow environment variables to be unset in osl_executeProcess (undocumented feature for now, and OS/2 code is not yet adapted)

- Old modifications were necessary for testshl2, which has simply been excluded
  from the build for now.
- Tests in basebmp, basegfx, o3tl (that are executed during build) have been
  converted from using modified CppUnit/testshl2 to using unmodified CppUnit.
- CppUnit's DllPlugInTester has problems with OOo tests on Windows, see
  #i107562#, so for now a new cppunittester from sal is used instead.

sb116: #i106384# removed unncessary assignments (that caused warnings about using uninitialized variables)
