call :
CatchChild();
*before* we fork the domain child. This call establishes a signal handler that
eats SIGCLD signals and doesn't call sys_select_signal() as the main daemon
SIGCLD handler should do. This causes the parent to ignore dead children and
time out, instead of calling winbind_child_died() on receipt of the signal. The
correct fix is to move the CatchChild call into the child code after the fork.

Thanks to Glenn Curtis and Kyle Stemen @ Likewise. Their explanation is:
In winbindd_dual.c, there is a list of children processes that
is maintained using macros DTLIST_ADD and DTLIST_REMOVE. In the
case when a scheduled_async_request fails, the particular child
was located in the list, and its attributes were cleared out
and it was reused for a subsequent async request. The bug was that
the new request would queue the same node into the doubly-linked
list and would result in list->next pointing to the same node as
list itself. This would set up an infinite loop in the processing of
the for loop when the list of children was referenced.
Solution was to fully remove the child node from the list, such that
it could be inserted without risk of being inserted twice.
Note that the child is re-added to the list in fork_domain_child() again.

We now open messages.tdb even before we do the become_daemon. become_daemon()
involves a fork and an immediate exit of the parent, thus the
parent_is_longlived argument must be set to false in this case. The parent is
not really long lived :-)

This patch make sure we do not try to contact smbd in the main dameon
to avoid deadlocks.
All the operations that require connecting to smbd are performed in
the domain child anyway.

The child struct is immediately reused, and this results
in a panic when child->logfilename == NULL.

Each cli struct has it's own local copy of this variable,
so use that in client code. In the smbd server, add one
static to smbd/proccess.c and use that inside smbd. Fix
a bunch of places where smb_rw_error could be set by
calling read_data() in places where we weren't reading
from the SMB client socket (ie. winbindd).

bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).
