This relates bach to strncpy() vs strlcpy() and things like asprintf() 
vs sprintf().  If you've not heard of it strlcpy() takes a parameter 
that determines the size of the _destionation_ buffer and not the source 
buffer.  This dramatically reduced the chance of buffer overruns.

I would prefer that these conversion functions always took a parameter 
that determined the size of the destination buffer.  If nothing else, 
could you code call it as something like hex2bin(src,dest,strlen(src))?
