* harbour/source/vm/estack.c
; added TODO note for TSD handles recovery system to document dynamic
(not static) TSD access as public API. Otherwise it's a risk to give
such interface for 3-rd party code developers due to potential
resource leak.
* harbour/contrib/hbct/ctwin.c
+ added support for thread local current window pointer in CT Windows.
Warning: each new thread uses window 0 as default.
* harbour/contrib/hbct/files.c
+ added MT support FILESEEK(), FILEATTR(), FILESIZE(), FILEDATE().
Warning: now each thread operates on it's own directory handle.
The directory handle is open until is not scanned to the end by
subsequent calls to FILESEEK() without parameters or by explicit
call with NIL or empty string "" as file name, f.e.: FILESEEK( NIL ).
Such method of closing directory handle is compatible with original
CT3 behavior.
