55f4802785 Prevent write operations on large objects in read-only transactions 
Attempting such an operation would already fail, but in various and
confusing ways.  For example, while in recovery, some elog() messages
would be reported, but these should never be user-facing.  This commit
restricts any write operations done on large objects in a read-only
context, so as the errors generated are more user-friendly.  This is per
the discussion done with Tom Lane and Robert Haas.

Some regression tests are added to check the case of all the SQL
functions working on large objects (including an update of the test's
alternate output).

664da2a389 Fix comment in regression tests for large objects 
The values assigned to INV_WRITE and INV_READ were reversed in the
tests, which would be confusing when writing tests specific to read or
write operations on LOs.

328dfbdabd Extend psql's \lo_list/\dl to be able to print large objects' ACLs. 
The ACL is printed when you add + to the command, similarly to
various other psql backslash commands.

Along the way, move the code for this into describe.c,
where it is a better fit (and can share some code).

dc9c3b0ff2 Remove dynamic translation of regression test scripts, step 2. 
"git mv" all the input/*.source and output/*.source files into
the corresponding sql/ and expected/ directories.  Then remove
the pg_regress and Makefile infrastructure associated with
dynamic translation.
