pull a string from a request packet, returning a talloced string
the string length is limited by the 3 things:
- the data size in the request (end of packet)
- the passed 'byte_len' if it is not -1
- the end of string (null termination)
Note that 'byte_len' is the number of bytes in the packet
on failure zero is returned and *dest is set to NULL, otherwise the number
of bytes consumed in the packet is returned
