71b69b0169 Revert "ctdb-common: Use SCHED_RESET_ON_FORK when setting SCHED_FIFO"
BUG: https://bugzilla.samba.org/show_bug.cgi?id=12392

Feature SCHED_RESET_ON_FORK is completely broken on RHEL6 and RHEL7
distributions.  So do not rely on SCHED_RESET_ON_FORK for now.

This reverts commit 1be8564e553ce044426dbe7b3987edf514832940.

4541301d92 ctdb-common: Fix CID 1363227 Resource leak (RESOURCE_LEAK)
Occurs on an invalid line that isn't the first.  Isn't really a leak
because it is allocated off mem_ctx, which should be freed by the
caller.

907a5a6f1b ctdb-common: New function ctdb_wait_for_process_to_exit()
This pattern is used quite a few times in the CTDB code.  Many
instances use ctdb_kill() but for signal 0 this just calls kill(2)
anyway.

a5be2c245d ctdb-daemon: Store node addresses as ctdb_sock_addr rather than strings
Every time a nodemap is contructed the node IP addresses all need to
be parsed.  This isn't very productive use of CPU.

Instead, parse each string once when the nodes file is loaded.  This
results in much simpler code.

This code also removes the use of ctdb_address.  Duplicating the port
is pointless without an abstraction layer around ctdb_address.  If
CTDB gets an incompatible transport in the future then add an
abstraction layer.

Note that the infiniband code is not updated.  Compilation of the
infiniband code is already broken.  Fixing it will be a separate,
properly tested effort.
