needs to be implemented.

* src/ttt-lex.h:
* src/ttt-lex.l:
* src/ttt-token.h: Add support for a flex-based tokenizer which
tokenizes newlines and space-separated strings.
* src/ttt-client.c: (_ttt_client_init), (_ttt_client_fini),
(_append_to_request), (_free_request), (_read_request),
(_execute_request): Use new tokenizer to tokenize input into an
array of request strings.

* src/Makefile.am:
* src/ttt-error.h:
* src/ttt-error.c: (ttt_error_string): Add error values and error
strings from protocol.
* src/ttt.h: Add typedefs for ttt_client_t and ttt_server_t so
that there's no problem with ttt-client.h and ttt-server.h needing
to mutually include each other.
* src/ttt-server.h:
* src/ttt-server.c: (ttt_server_register_client),
(ttt_server_unregister_client), (_ttt_server_accept), (main): Push
the client request handling thread back down into ttt-client.c
where it really does belong. The server code no longer ever
reaches down inside the ttt_client_t structure. Export
ttt_server_register_client and ttt_server_unregister_client. Add
documentation for ttt_server_broadcast. Document locking semantics
for all functions which acquire the server lock.
* src/ttt-client.h:
* src/ttt-client.c: (_ttt_client_create), (_ttt_client_destroy),
(_read_into_request_until), (_read_request), (_execute_request),
(_handle_requests_thread), (ttt_client_new), (ttt_client_get_id):
Pull the ttt_client structure definition back down inside the
ttt-client.c file. Don't export ttt_client_create and
ttt_client_destroy anymore, but instead just use static
_ttt_client_init and _ttt_client_fini. Implement the broadcast by
just passing a client pointer around and using client->request
rather than passing char *request all over. Document new
ttt_client_new and remove ttt_client_read_line. Add locking to
ttt_client_send and document it. Add ttt_client_get_id.

Server now acts as a very simple chat server.
* src/ttt-client.h:
* src/ttt-client.c: (ttt_client_create), (ttt_client_destroy),
(_append_to_request), (ttt_client_read_into_request_until),
(ttt_client_read_line), (ttt_client_send): Add support to do a
buffering read within the client and to reuse the buffer (which
grows by doubling) from one request to the next. Add function to
send a message to a client.
* src/ttt-server.c: (ttt_server_init), (ttt_server_create_client):
Add support for a client idea. Resize the server's client list by
doubling.
* src/ttt-server.c: (ttt_server_destroy_client): Add support to
destroy a client.
* src/ttt-server.c: (_handle_client_requests_thread),
(_accept_client): Move handling of client requests up to
ttt-server.c from ttt-client.c. Use threads rather than a fork per
client.
* src/ttt-server.h:
* src/ttt-server.h: (ttt_server_broadcast): Add function to send a
message to all connected clients.
* src/ttt-socket.h:
* src/ttt-socket.c: (ttt_socket_read),
(ttt_socket_write): Add functions to do blocking read or write of
the specified number of bytes.
* src/ttt-socket.c: (ttt_socket_accept): Remove fork, so that the
accept function call can take care of anything like that itself.
* src/x.h:
* src/x.c: (xread), (xwrite): New wrappers for read and write.
* src/ttt.h: Add TTT_STATUS_EOF, TRUE, and FALSE.
* src/ttt.c: Need to include ttt-args.h explicitly now.

* src/ttt-server.h:
* src/ttt-server.c: (ttt_server_init), (ttt_server_add_client),
(_accept_client), (main): Add a new ttt_server_t object with a
mutex-protected list of clients. Move client handling code down
into new ttt-client.c.
* src/ttt-client.h:
* src/ttt-client.c: (ttt_client_create), (ttt_client_destroy),
(ttt_client_handle_requests): New ttt_client_t object that simply
holds a pointer back to the server as well as the client socket
file descriptor.
* src/ttt-socket.h:
* src/ttt-socket.c: (ttt_socket_accept): Add closure argument. Add
a call to fork before calling the accept callback.
* src/ttt-args.c: Hide unused ttt_args_usage from the compiler to
keep it from complaining.
* src/ttt.c: (main): Rename the client main program from
ttt-client to ttt.c, (since the server code now has its own
ttt-client.c).
* src/ttt.h:
* src/Makefile.am: Include and link with pthread now that we have
pthread-based mutex locking.

code out of ttt-server.c down into a new ttt_socket abstraction
layer. The code is much easier to read now. The server also no
longer exits when the first client exits, but continues to listen
for more connections.

* src/x.c: (xasprintf), (xvasprintf), (xpipe), (xfork), (xmalloc),
(xcalloc), (xrealloc), (xfdopen), (xstrdup), (xfwrite): Several
utility functions that make system calls, check the result, and
exit on any error. This will simplify the error checking needed in
programs using these functions.
