e4adf55e24 winbindd: Add retry also for ADS method calls
RPC calls can return IO_DEVICE_ERROR on expired SMB2 sessions. Retrying
on a new connection avoids surfacing this error to winbindd clients.

7cd99b4207 idmap_rfc2307: Fix handling of cn realm
When cn_realm was set, the idmap_rfc2307 module tried to determine the
realm from the AD connection struct. In case of referring to a different
domain using the ldap_domain config option, the wrong realm was used.

Since the LDAP-server case already requires having the realm in the
config, extend that to the AD case to fix the issue: Having LDAP records
with @realm in the cn, now always requires having the realm in the
config.

Now cn_realm and ldap_realm always would have to be specified together,
so replace the two options with a single "realm" option.

ef0c911955 idmap: Initialize all idmap domains at startup
So far we have initialized idmap domains on demand indexed by name.
For sid2xid this works okay, because we could do lookupsids before
and thus get the name. For xid2sid this is more problematic. We
have to rely on enumtrustdoms to work completely, and we have to
look at the list of winbind domains in the parent to get the domain
name. Relying on domain->have_idmap_config is not particularly nice.

This patch re-works initialization of idmap domains by scanning all
parametric parameters, scanning for :backend configuration settings.
This way we get a complete list of :range definitions. This means
we can rely on the idmap domain array to be complete. This in turn
means we can live without the domain name to find a domain, we can
do a range search by uid or gid.

Also, finding the oldest idle client for removing an 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.

When cancelling a request at the main winbindd process, that is currently
being served by a child winbindd process, just freeing all objects related
to the request is not enough, as the next bytes to come through the pipe
from the child process are the response to the cancelled request, and the
object reading those bytes will be the next request. This breaks the protocol.

This change, upon canceling a request that is being served, closes the
connection to the child process, causing the next request to be served
by a new child process (and the detached child to die eventually).
