ALTER TABLE OWNER must change the ownership of the table's rowtype too.
This was not especially critical before, but it is now that we track
ownership dependencies --- the dependency for the rowtype *must* shift
to the new owner. Spotted by Bernd Helmle.
Also fix a problem introduced by recent change to allow non-superusers
to do ALTER OWNER in some cases: if the table had a toast table, ALTER
OWNER failed *even for superusers*, because the test being applied would
conclude that the new would-be owner had no create rights on pg_toast.
A side-effect of the fix is to disallow changing the ownership of indexes
or toast tables separately from their parent table, which seems a good
idea on the whole.

into .def and .exp files automatically on Windows, AIX, and the like.
An additional benefit is that changes in libpgport files correctly
propagate to force rebuild of the backend executable. This is my
reworking of Rocco Altier's idea, and if it breaks anything it's
definitely my fault.

Fix a whole bunch of #includes that were either wrong or redundant.
The first rule of portability for us is 'thou shalt have no other gods
before c.h', and a whole lot of these files were either not including
c.h at all, or including random system headers beforehand, either of
which sins can mess up largefile support nicely. Once you have
included c.h, there is no need to re-include what it includes, either.

Remove some long-dead support for libpgtcl with Tk.

Fix a few macro definitions to ensure that unary minus is enclosed in
parentheses. This avoids possible operator precedence problems, and
is consistent with most of the macro definitions in the tree.

Avoid crashing pg_dump if we can't connect to the database server, and
no database has been explicitly specified. Per gripe from Omar Kilani.

Basic documentation for ROLEs. The user-manag chapter still needs to
be rewritten, but at least the reference pages are reasonably sane.
