Parsing null terminated strings in a binary.

[Raimo Niskanen]

Parse the binary in a loop something like this (untested):

z_split(<<B1:N/binary,0,B2/binary>>, N) ->
    {B1,B2};
z_split(<<B1:N/binary>>, N) ->
    B1;
z_split(<<_:N/binary,_/binary>>=B, N) ->
    z_split(B, N+1).

This will not build any sub-binaries until the zero is found.
