* harbour/include/hbapigt.h
* harbour/source/rtl/gtapi.c
+ added C functions hb_gtLock() and hb_gtUnlock()
They block current GT for other threads
* harbour/source/rtl/gtfunc.c
+ added PRG functions hb_gtLock() and hb_gtUnlock()
They block current GT for other threads - be careful using them
and always unlock locked GT
* harbour/source/rtl/scroll.c
+ added HB_SCROLL() function - it works like SCROLL() but supports
2 additional parameters: color and erase char. It's stateless and
atomic in GT access
* harbour/source/rtl/tbrowse.prg
* use HB_SCROLL() instead of SCROLL(). Now whole TBROWSE class
does not depend on other thread screen output and does not
set any GT variables except of cursor positioning to active
cell when it's enabled
* harbour/source/rtl/memoedit.prg
* harbour/source/rtl/tgetlist.prg
* harbour/source/rtl/tlabel.prg
* harbour/source/rtl/listbox.prg
* harbour/source/rtl/tmenusys.prg
* harbour/source/rtl/achoice.prg
* harbour/source/rtl/profiler.prg
* harbour/source/rtl/teditor.prg
* use atomic stateless functions when possible - this code should
be checked and updated by some who know it.
