optional fd_set pointer is used to have the fixup code for unreliable
returns of FD_ISSET() at one place only.

audiod: Fix status item parsing for long status items.
This was broken since audiod started to use the buffer tree API. Actually there are
two bugs which are both fixed by this patch:
- for_each_stat_item() copies the remaining part of the buffer containing
the incomplete part of the last status item to the beginning of the buffer.
This is necessary if the buffer tree API is not used but messes up the buffer
contents if it _is_ used. Move this memmove() call from for_each_status_item(),
which is called from audiod.c and gui.c, to gui.c, as only gui.c needs it.
- Secondly, audiod.c called btr_node_status() with an minimum input queue
size of zero, which is does not work if a status item crosses a buffer
boundary. In this case for_each_status_item() will only ever see the first buffer
containing the incomplete status item, hence it can never make progress.
Fix this by introducing the min_iqs field of struct status_task. Set this field
to non-zero if the full buffer size was returned by for_each_status_item(),
indicating that the next status item is spread out over two or more buffers.

main: recv syntax error
The CCID negotiation can be watched in wireshark, between the 'Request'
packet sent by the para_client and the corresponding 'Response' packet of
the para_server. Here are some example negotiations:
+-------------+---------------+----------------+
| client-list | server-list | resulting CCID |
+-------------+---------------+----------------+
| 3, 2 | 2, 3, 4 | 2 |
| 4, 3, 2, 4 | 3, 2, 4 | 3 |
| 2, 4 | 2, 3, 4 | 2 |
| 4, 3, 2, 4 | 2, 3, 4 | 2 |
| 2 | 2, 3, 4 | 2 |
| 3 | 2, 3, 4 | 3 |
| 4 | 2, 3, 4 | 4 |
+-------------+---------------+----------------+
The server list of (2, 3, 4) is the unaltered default, it can be changed on
the server using the same mechanism.
As shown, the easiest way is to use just a single '--ccid <n>' argument;
when passing multiple values, the outcome is determined by the algorithm
described in RFC 4340, 6.3.1:
* 'server-priority' means that the server overrids the result;
* the server traverses its list of preferences in order of priority and
* uses the first entry which also appears in the client-list;
* resets connection with negotiation failure when there is no common value.
Applying this algorithm on the above lists can be used to verify the
table. This also illustrates that repetition of CCID values has no effect
on the outcome: if the repeated value is first in the server list, it will
be chosen; otherwise all instances of that value are ignored.

This is a refactoring of makesock():
* the ubiquitous AF_UNSPEC is promoted as the default;

* para_listen() now supports flowopts;
* a wrapper for passive sockets, para_listen_simple();
* for consistency, port numbers (which are 2 byte in
UDP, TCP, and DCCP) have all been set to 'uint16_t'.

07_flow-opt-support.diff
In order to support a class of socket options which have to be set
before commiting a socket to a connection, this patch adds an API
for "pre-connection" socket options, called "flowopts" here.
The API is used as follows:
* to provide queue storage, a new head is allocated using flowopt_new();
* this queue is then populated with pre-connection socket options via
- generic 'add' method flowopt_add(),
- a specific variant for adding Boolean options - flowopt_add_bool(),
- convenience macros - OPT_ADD(), OPT_ENABLE(), OPT_DISABLE();
* the rest is then dealt with automatically by makesock():
- any provided flowopts are set before making the connection,
- due to using a queue, the order of invocation is preserved,
- after making the connection, makesock() frees storage that has been
previously allocated by flowopt_new() and flowopt_add.*().

05_dccp-supported-ccid-lookup.diff
This adds a self-contained function to return the space-separated list of
CCIDs available on the para_server. Visible via 'para_client si'.
Since feature negotiation for CCIDs is supported only from v2.6.30-rc1
(released 7th April 2009), a more recent kernel (>= 2.6.30) is needed to
support this feature, as well as subsequent per-connection use of CCIDs.
Note: This patch still uses a hardcoded upper bound (DCCP_MAX_HOST_CCIDS),
support dynamically detecting the number of CCIDs will be in 2.6.33.

04_per-connection-ccid-constants.diff
This adds symbolic constants for per-connection CCID support; these are used

Per-connection CCID support is available in the Linux kernel from v2.6.30-rc1
(7th April 2009) onwards, further information is available at:
* symbolic names are taken from include/linux/dccp.h,
* API documentation is in Documentation/networking/dccp.txt.
The patch also corrects the manner of using doxygen comments in the #defines.

03_resolve-port-names.diff
This patch allows to resolve port numbers into names defined
in the services(5) /etc/services database:
(a) it provides a standalone function which will fall back to
stringifying a port number;
(b) it resets the 'numeric service' flag of getnameinfo(3) to
analogously consider a lookup in /etc/services.
Assuming the following had been added to /etc/services:
para_server_control 2990/tcp # para_server control
paraslash_http_service 8000/tcp # paraslash http sender
paraslash_dccp_service 8000/dccp # paraslash dccp sender
paraslash_udp_service 8000/udp # paraslash udp sender,
then the output of 'para_client si' would look like:
http sender:
status: on
port: paraslash_http_service
...
dccp sender:
status: on
port: paraslash_dccp_service
...
udp sender:
status: on
port: paraslash_udp_service
...
Note: On some systems the service lookup may involve LDAP or NIS lookups,
depending on the 'services' configuration in /etc/nsswitch.conf. This does
not seem to cause a problem, as it implies a working network connection.

01_convert-v6-mapped-v4-addresses.diff
This updates the resolution of v4/v6 addresses to present v6-mapped-v4
addresses in dot-quad format rather than as subtype of v6 address.
The getnameinfo(3) is in use for both address classes, where potential
DNS lookups (requiring Internet connectivity) are avoided by using the
NI_NUMERICHOST flag.
The use of this flag reduces getnameinfo() to inet_ntop(3). In the 'Bugs'
section of the inet_ntop() manpage it is stated that v6-mapped-v4 addresses
are converted into an IPv6 format, which is what had been observed here.
The patch works around the issue by casting the v6-mapped-v4 address into
a genuine AF_INET IPv4 socket address.
