core,w32: Add UTF-8 support to gpgrt_fopen, gpgrt_mkdir and gpgrt_chdir.

* src/protos.h: New.
* src/Makefile.am (libgpg_error_la_SOURCES): Add file.
* src/gpgrt-int.h: Include protos.h.
* src/sysutils.c (_gpgrt_mkdir) [W32]: Make UTF-8 aware.
(_gpgrt_chdir) [W32]: Ditto.
* src/w32-gettext.c: Include protos.h.
(utf8_to_wchar): Allow for strings.
(_gpgrt_utf8_to_wchar): New.
(_gpgrt_free_wchar): New.
* src/estream.c (map_w32_to_errno): Add more error codes.
(_gpgrt_w32_set_errno): New.
(any8bitchar) [W32]: New helper.
(func_file_create) [W32]: Convert file name and use _wopen.
