* src/vm/set.c
    ! fixed freed memory access exploited by interactions between
      modifications in last few years.
    ! do not try to remove trailing ^Z char reading from the stream
      if FS_END seek reports 0.
    ! if possible open printer/alternate/extra output in write only mode
      to avoid problem on devices where read access is not available.

  * src/rtl/langapi.c
    * keep EN lang active after deinitialization

  * src/rtl/filesys.c
    ! fixed condition for file time refresh in *nix builds
    ! fixed file time setting in *nix builds

  * include/hbapifs.h
  * src/rtl/Makefile
  * src/rtl/filebuf.c
  + src/rtl/filebufd.c
    * renamed hb_fileRegister2() to hb_fileRegisterFull()
    + added new function hb_fileRegisterPart() which simplifies writing
      small FILE IO redirectors.

  * contrib/hbmemio/memio.c
  * contrib/hbnetio/netiocli.c
    * use hb_fileRegisterFull()

  * contrib/hbplist.txt
  + contrib/hbtcpio/hbtcpio.hbc
  + contrib/hbtcpio/hbtcpio.hbp
  + contrib/hbtcpio/hbtcpio.hbx
  + contrib/hbtcpio/tcpio.c
    + added new Harbour FILE IO redirector.
      It recognizes and process names with "tcp:" prefix, in form like:
         tcp:<host>:<port>[:<timeout>]
      It can be used in different subsystems using Harbour FILE IO and
      stream read/write operations, i.e.
         REQUEST HB_TCPIO
         SET PRINTER TO tcp:192.168.0.110:9100
      can be used to connect to network printers using TCP direct printing.

  * utils/hbmk2/po/hbmk2.pt_BR.po
    ! fixed typo in translation
