* harbour/source/rtl/gtchrmap.c
* harbour/source/rtl/gttrm/Makefile
* harbour/source/rtl/gttrm/gttrm.c
+ set Id keyword property
* harbour/source/common/expropt1.c
! fixed typo in HB_TRACE() parameters
* harbour/include/hbapicdp.h
* harbour/include/hbapirdd.h
* harbour/source/rtl/strcase.c
* harbour/source/rtl/is.c
* harbour/source/rtl/gtxwc/gtxwc.h

* harbour/source/rdd/dbfcdx/dbfcdx1.c
* harbour/source/vm/hvm.c
! fixed compilation with HB_CDP_SUPPORT_OFF - I do not plan to
create such builds but now these macro allow to easy locate
CDP dependent code
* harbour/include/hbextern.ch
* harbour/source/rtl/cdpapi.c
+ added two prg functions for translations from/to UTF-8:
HB_STRTOUTF8( <cStr> [, <cCPID> ] ) -> <cUTF8Str>
HB_UTF8TOSTR( <cUTF8Str> [, <cCPID> ] ) -> <cStr>
<cCPID> is Harbour codepage id, f.e.: "EN", "ES", "ESWIN",
"PLISO", "PLMAZ", "PL852", "PLWIN", ...
When not given then default HVM codepage (set by HB_SETCODEPAGE())
is used.
