test, rather than a number of test cycles.  Changes -o/cycles option to
-s/seconds.

O_DIRECT behavior.

This isn't fully tested as yet, in particular I'm not sure that the
"foo--unpackaged--1.0.sql" scripts are OK.  But it's time to get some
buildfarm cycles on it.

sepgsql is not converted to an extension, mainly because it seems to
require a very nonstandard installation process.

always 8k writes, per suggestion from Tom.  Also adjust open_sync output
layout.

it is 8k as expected.

Reduce #includes to minimum actually needed; in particular include
postgres_fe.h not postgres.h, so as to stop build failures on some
platforms.

Use get_progname() instead of hardwired program name; improve error
checking for command line syntax; bring error messages into line with
style guidelines; include strerror result in die() cases.

Per buildfarm.

Un-break Windows build (I hope) by making the HAVE_FSYNC_WRITETHROUGH
code match the backend.  Fix incorrect program help message.  static-ize
all functions.

Actually rename the program, rather than just claiming we did.  Hook it
into the build system.  Get rid of useless dependency on libpq.  Clean up
#include list and messy whitespace.
