Make archiver process an auxiliary process.
This commit changes WAL archiver process so that it's treated as
an auxiliary process and can use shared memory. This is an infrastructure
patch required for upcoming shared-memory based stats collector patch
series. These patch series basically need any processes including archiver
that can report the statistics to access to shared memory. Since this patch
itself is useful to simplify the code and when users monitor the status of
archiver, it's committed separately in advance.
I think this needs to handle ProcSignalBarrierPending. Otherwise,
code that tries to use proc signal barriers (like CF #2962 and #2602)
might hang forever when an archiver is running.
Thanks for the comment! I will investigate this.
