The adminpack extension was only used to support pgAdmin III, which
in turn was declared EOL many years ago. Removing the extension also
allows us to remove functions from core as well which were only used
to support old version of adminpack.

The user receiving the message might not understand where the
server's "current directory" is. "Data directory" seems clearer.
(This would not be good for frontend code, but both of these
messages are only issued in the backend.)

Teach canonicalize_path() how to strip all unnecessary uses of "."
and "..", replacing the previous ad-hoc code that got rid of only
some such cases. In particular, we can always remove all such
uses from absolute paths.
The proximate reason to do this is that Windows rejects paths
involving ".." in some cases (in particular, you can't put one in a
symlink), so we ought to be sure we don't use ".." unnecessarily.
Moreover, it seems like good cleanup on general principles.
There is other path-munging code that could be simplified now, but
we'll leave that for followup work.
It is tempting to call this a bug fix and back-patch it. On the other
hand, the misbehavior can only be reached if a highly privileged user
does something dubious, so it's not unreasonable to say "so don't do
that". And this patch could result in unexpected behavioral changes,
in case anybody was expecting uses of ".." to stay put. So at least
for now, just put it in HEAD.

read_binary_file(), used by SQL functions pg_read_file() and friends,
uses stat to determine file length to read, when not passed an explicit
length as an argument. This is problematic, for example, if the file
being read is a virtual file with a stat-reported length of zero.
Arrange to read until EOF, or StringInfo data string lenth limit, is
reached instead.
Original complaint and patch by me, with significant review, corrections,
advice, and code optimizations by Tom Lane. Backpatched to v11. Prior to
that only paths relative to the data and log dirs were allowed for files,
so no "zero length" files were reachable anyway.

This function allows us to fsync the specified file or directory.
It's useful, for example, when we want to sync the file that
pg_file_write() writes out or that COPY TO exports the data into,
for durability.

This provides a newer version of adminpack which works with the newly
added default roles to support GRANT'ing to non-superusers access to
read and write files, along with related functions (unlinking files,
getting file length, renaming/removing files, scanning the log file
directory) which are supported through adminpack.
Note that new versions of the functions are required because an
environment might have an updated version of the library but still have
the old adminpack 1.0 catalog definitions (where EXECUTE is GRANT'd to
PUBLIC for the functions).
This patch also removes the long-deprecated alternative names for
functions that adminpack used to include and which are now included in
the backend, in adminpack v1.1. Applications using the deprecated names
should be updated to use the backend functions instead. Existing
installations which continue to use adminpack v1.0 should continue to
function until/unless adminpack is upgraded.
