Heikki Linnakangas 21ef4d4d89 Revert "libpqwalreceiver: Convert to libpq-be-fe-helpers.h"
This reverts commit 728f86fec6.

The signal handling was a few bricks shy of a load in that commit,
which made the walreceiver non-responsive to SIGTERM while it was
waiting for the connection to be established. That prevented a standby
from being promoted.

Since it was non-essential refactoring, let's revert it to make v16
work the same as earlier releases. I reverted it in 'master' too, to
keep the branches in sync. The refactoring was a good idea as such,
but it needs a bit more work. Once we have developed a complete patch
with this issue fixed, let's re-apply that to 'master'.
