Hi,

this is the latest and obviously best version of xlogreader & xlogdump with
changes both from Heikki and me.

Changes:
* windows build support for pg_xlogdump
* xlogdump moved to contrib
* xlogdump option parsing enhancements
* generic cleanups
* a few more comments
* removal of some ugliness in XLogFindNextRecord

I think its mostly ready, for xlogdump minimally these two issues remain:

const char *
timestamptz_to_str(TimestampTz dt)
{
return "unimplemented-timestamp";
}

const char *
relpathbackend(RelFileNode rnode, BackendId backend, ForkNumber forknum)
{
return "unimplemented-relpathbackend";
}

aren't exactly the nicest wrapper functions. I think its ok to simply copy
relpathbackend from the backend, but timestamptz_to_str? Thats a heck of a lot
of code.

Patches 1 and 2 and 5 are just preparatory and probably can be applied
beforehand.

3 and 4 are the real meat of this and especially 3 needs some careful review.

Input welcome!

Andres
