Paul Eggert 7d07690e5d emacsclient receiving long-line fixes ...

Do not mishandle long lines, or lines containing NUL,
when receiving data.
* lib-src/emacsclient.c (check_socket_timeout, main):
Use ssize_t for return values from recv,
since in theory the value could exceed INT_MAX now.
(main): Do not use a fixed-size buffer for receiving data;
instead, grow the buffer as needed (admittedly unlikely).
When a partial line is received via recv, do not discard its data;
instead, keep reading, possibly with a grown buffer.
Do not ignore received data after a null byte is received.
Add a comment about when received data is ignored due to a goto.
