GCC8 shows the following compile warning:
cmsfs-fuse.c: In function ‘convert_text’:
cmsfs-fuse.c:2558:19: warning: passing argument 2 to restrict-qualified
parameter aliases with argument 4 [-Wrestrict]
rc = iconv(conv, &data_ptr, &in_count, &data_ptr, &out_count);
^~~~~~~~~ ~~~~~~~~~
Fix this by using a separate buffer for iconv. The buffer size depends on
the record format: variable-length records have a maximum length of
MAX_RECORD_LEN (plus 1 byte for linefeed), while fixed-length records
could be larger in theory. This patch takes that into account for the iconv
buffer, but the rest of the code currently cannot handle fixed-length records
larger than MAX_RECORD_LEN.
