Receive a binary encoded 'picture' message from the socket (or actor).
This method is similar to zsock_recv, except the arguments are encoded
in a binary format that is compatible with zproto, and is designed to
reduce memory allocations. The pattern argument is a string that defines
the type of each argument. See zsock_bsend for the supported argument
types. All arguments must be pointers; this call sets them to point to
values held on a per-socket basis.
For types 1, 2, 4 and 8 the caller must allocate the memory itself before
calling zsock_brecv.
For types S, the caller must free the value once finished with it, as
zsock_brecv will allocate the buffer.
For type s, the caller must not free the value as it is stored in a
local cache for performance purposes.
For types c, f, u and m the caller must call the appropriate destructor
depending on the object as zsock_brecv will create new objects.
For type p the caller must coordinate with the sender, as it is just a
pointer value being passed.
