Fixes bug #12929. Uses my_cgets instead of _cgets function, thus eliminating

a restriction to 255 chars for editable buffer.


VC++Files/mysys/mysys.dsp:
  Added my_conio.c
VC++Files/mysys/mysys_ia64.dsp:
  Added my_conio.c
include/my_sys.h:
  Added declarations for my_conio.c functions
mysys/my_conio.c:
  Added _cgets() replacement that is not limited to 255 chars retrieval
  from win32 console.
