credentials.c:
use UTIME structure (defined and commented in smb.h to be time, secs, since 01jan1970) pipes.c: another sub-function. util.c: added char *unistr2(uint16 *buff) function. same as unistr except it takes uint16* instead of char*. smbparse.c smb.h: more structure sorting. proto.h: the usual. (This used to be commit 72a86f514f0c92b69499718e63f5dd73ebece56e)
