Cleanup for vacuum help, manual page, and error message

Fix inclusion of 'tas.s' for various ports

 been set in the session.
General cleanup of timezone support code.

Define functions and operators for closest point to lseg on box,
 to line on lseg, to lseg on lseg.
Define function and operator for length of lseg.
Change length operator from '??' to '@-@'
 (currently defined for path and lseg).

Define close_ls(), close_lseg(), lseg_length().
Write real code for close_sb(), close_pb(), inter_sb(), inter_lb().
Repair lseg_perp() which determines if two lsegs are perpendicular.
Repair lseg_dt() distance between two lsegs.
Note: close_sl() is clearly broken  but will repair later
 (calculating point on lseg rather than point on line).

Slight cleanups for glibc2.0

[This is a repost - it supercedes the previous one. It fixes the patch so
it doesn't bread aix port, plus there's a file missing out of the
original post because difforig doesn't pick up new files. It's now
attached. peter]

This patch brings the JDBC driver up to the current protocol spec.
Basically, the backend now tells the driver what authentication scheme to
use.

The patch also fixes a performance problem with large objects. In the
buffer manager, each fastpath call was sending multiple Notifications to
the backend (sometimes more data in the form of notifications were being
sent than blob data!).

related to grammar and parser issues, with one postmaster fix.

if an operating specific expected file exists, use that for the comparison.
This allows for "legit" differences between results, like the "Result too

Also, have the failed diffs get output to regression.diffs so that its easy to
view those tests that failed

I haven't had final confirmation from Peter yet, but the attached patch
needs to be applied for the Beta otherwise password and crypt
authentication just won't work.

It puts back the loop in libpq and also fixes a couple of problems with
maintaining compatability with pre-6.3 drivers.
