Bug fix: ECMA-119 ".." pointed always to the same block as ".".

Bug fix: iso_write_opts_set_rrip_version_1_10() caused wrong size of
         root record CE,
Stability enhancement: util.c:str2ascii() got a fallback for the case
                       that charset "WCHAR_T" is not available,
Debugging wrapper around iconv*() calls,
Experiments about inode numbers in fs_image,
Experiment to insert obsolete RR entries.
(Sorry for the obfuscation. Most is due to a hard ride on Solaris.
