[PATCH] #5 OS400/EBCDIC Port: functions that require ebcdic

Hello All,

(Don't know what the OS400/EBCDIC port is about? See:
http://svn.haxx.se/dev/archive-2006-02/0519.shtml)

Despite IBM's UTF support, some functions still require EBCDIC strings.
IBM's documentation says it clearly, if not comprehensively:

"Nearly all of the run-time routines have been modified to support UTF,
but there are a handful of them that have not...Other operating system
routines have not been modified to support UTF. For example, the IFS
routines such as open() still accept job CCSID. Other operating system
APIs also still accept job CCSID"

The "other APIs" include symlink() and readlink(). This patch converts
the arguments to these three functions to the required encoding when
running on OS400.

Please review if you have a moment, thanks,

Paul B.

[[[
OS400/EBCDIC Port: Convert string args to EBCDIC for functions that
require it.

This is one of several patches to allow Subversion to run
on IBM's OS400 V5R4.

Despite V5R4's UTF support, a handful of functions on OS400 still
require EBCDIC encoded string arguments.

* subversion/libsvn_subr/cmdline.c
   (svn_cmdline_init): Convert string args to open() to EBCDIC.

* subversion/libsvn_subr/io.c
   (SVN_UTF_UTOE_XLATE_HANDLE): New xlate key for UTF-8 (CCSID 1208)
    to EBCDIC (CCSID 0) conversions.
   (svn_io_create_unique_link): Convert string args to symlink() to
    EBCDIC.
   (svn_io_read_link): Convert string args to readlink() to EBCDIC.
