This is a security audit change of the main source.
It removed all ocurrences of the following functions :
sprintf
strcpy
strcat
The replacements are slprintf, safe_strcpy and safe_strcat.
It should not be possible to use code in Samba that uses
sprintf, strcpy or strcat, only the safe_equivalents.
Once Andrew has fixed the slprintf implementation then
this code will be moved back to the 1.9.18 code stream.
Jeremy.
