Revert SignalSomeChildren function back to Postgres 9.2 functionality
Revert SignalSomeChildren function back to Postgres 9.2 functionality

Currently, the walsender process is not properly stopped during
gpstop. The SignalSomeChildren function was changed in the Postgres
8.3 merge in commit 20ac0be199f07f75025311538cf15cd96ffe2108. It was
previously at a Postgres 9.2 state to support sending signals to
walsender as a part of our master and standby master replication.
