safestring bug. patch attached

[Markus Wuebben]

Hi!

scopy() in safestring.c has a bug. Just start vdelivermail(from vpopmail
4.8.7) from the shell 
and it wil segfault. This is due to a bug in scopy.
It doesnt check if the char *src pointer is null...Well have a look 
yourself. 

a patch is attached. hopefully it is useful. Wasn't made with much thought.

Later,

Markus
