header.c: bug corrected

address.c mime.c misc.c: Always cast to (unsigned char) when using the ctype
functions like isspace();
mbx_default.c: If _PATH_SENDMAIL not set via paths.h use "/usr/spool/mail"
message.c: uidl is now <md5 . time . sequene>
tcp.c: INADDR_NONE is not define on solaris define it to -1.
