d8a01d09c1 winbind: winbind_messaging_context -> server_messaging_context
Don't use winbind_messaging_context anymore.

This fixes a bug analysed by Peter Somogyi <PSOMOGYI@hu.ibm.com>: If a
parent winbind forks, it only called reinit_after_fork on
winbind_messaging_context. On the other hand, deep in dbwrap_open we use
server_messaging_context(). This is not reinitialized by
winbind_reinit_after fork, so the parent and child share a ctdb
connection. This is invalid, because replies from ctdb end up in the
wrong process.

2c1c567ee1 winbindd: shorten client list scan
Counting on the client list being sorted by last access time,
the list scan for removing timed-out clients is shortened - once
the list is scanned oldest to newest, and once a non-timed-out
client is found, the scan can stop.

Also, finding the oldest idle client for removing an idle client
is simplified - oldest idle client is last idle client.

0c6dc1ecf9 async_req: check for errors when monitoring socket for readability
Add an option to wait_for_read_send(), so that the request, upon
calling back, report whether the socket actually contains data
or is in EOF/error state. EOF is signalled via the EPIPE error.

This is useful for clients which do not expect data to arrive but
wait for readability to detect a closed socket (i.e. they do not
intend to actually read the socket when it's readable). Actual data
arrival would indicate a bug in this case, so the check can
be used to print an error message.

28e1cae491 winbindd: cleanup client connection if the client closes the connection
This patch allows for early cleanup of client connections if the client
has given up.
Before this patch, any received request would be processed, and then only
upon transmitting the result to the client would winbindd find out the
client is no longer with us, possibly leading to a situation where the
same client tries over and over and increases the number of client
connections.

This patch monitors the client socket for readability while the request
is being processed, and closes the client connection if the socket
becomes readable. The client is not supposed to be writing anything to
the socket while it is waiting, so readability means either that the client
has closed the connection, or that it has broken the protocol.
