This patch enables building pgbench to use ppoll() instead of select()
to allow for more than (FD_SETSIZE - 10) connections. As implemented,
when using ppoll(), the only connection limitation is system resources.
The patch has been implemented to introduce a minimal of #ifdef/#ifndef
clutter in the code.
Two patches attached.
One based on REL9_6_STABLE.
One based on 'master' which can also apply to REL_10_STABLE.
