[Freeipa-devel] [PATCH][SSSD] Monitor configuration changes

[Stephen Gallagher]

First set of changes to the monitor to support live configuration reloads.

Patch 0001: Change the build system so that the monitor's service pipe
is fixed at compile-time.
Patch 0002: Enable the monitor to handle SIGHUP to start, stop and
update running children without always restarting them. Note,
configuration changes where the binary path or provider type has changed
will still necessitate a child process restart.

The monitor will signal the children through the SBUS to shut down
gracefully, but if they do not yet implement it or are unable to do so
within the specified timeout, the monitor will kill them with a POSIX
signal. Whenever the monitor's configuration changes, it will send a
message to all registered children to reread their configuration as
well. At the moment it doesn't care whether they succeed at this or not
(TODO)
