Change the multibyte character set support so that
Kanji support is one case of multibyte character support, rather than being a specific case in single byte character support. This allows us to add Big5 Chinese support (code page 950) and Korean Hangul support (code page 949) at very little cost. Also allows us to easily add future multibyte code pages. Makefile: Added codepages 949, 950 as we now support more multibyte codepages. asyncdns.c: Fixed problem with child being re-spawned when parent killed. charcnv.c charset.c client.c clitar.c kanji.c kanji.h smb.h util.c loadparm.c: Generic multibyte codepage support (adding Big5 Chinese and Korean Hangul). nmbd.c: Fixed problem with child being re-spawned when parent killed. mangle.c: Modified str_checksum so that first 15 characters have more effect on outcome. This helps with short name mangling as most 'long' names are still shorter than 15 chars (bug was foobar_mng and foobar_sum would hash to the same value, with the modified code they hash differently. Jeremy. (This used to be commit 299016338cfb47f0c585875ef9b468121fcee97d)
