There is not much value in asserting that a pointer parameter is non-null
if that parameter is always dereferenced.

terminal UI: Fix circumstances when errors should be logged to stdout.
The logic here was supposed to be that, if errors weren't already being
logged explicitly and if no output driver was already directed to stdout,
then send errors to standard output. But one of the conditions was
reversed. This fixes the problem.

procedure: Fix LIST procedure (and others) in GUI.
John Darrington reported that the following syntax makes PSPPIRE
crash:
data list list /alpha * beta * gamma *.
begin data.

end data.
list.
The problem is that the GUI output driver keeps a reference to the
output_items that are submitted to it. An output_item that in turn
has a reference to the casereader for the procedure casereader (that
is, the casereader returned by proc_open()), which currently is LIST
and few if any other procedures, then causes an assertion failure in
proc_commit(). This is because until now a precondition of
proc_commit() has been that the procedure casereader be closed, which
is what the assertion enforces.
This commit fixes the problem by getting rid of the precondition on
proc_commit(). Now the procedure casereader's lifetime may be
extended arbitrarily. This should help take PSPP output in the
direction that I want it to go, where more and more output is
generated directly or semi-directly from casereaders, as the LIST
procedure now does.

casereader: Factor buffering shim out into separate source file.
This moves the "shim" code out of casereader.c into a separate
casereader-shim.[ch] in preparation for using it from procedure.c.
This commit also adds an optimization: if the shim reads all of the
subreader, then it closes the subreader immediately, instead of waiting
for the shim itself to be destroyed. This can allow resources to be freed
earlier.
This commit also adds a new function casereader_shim_slurp(). This
function will be used for the first time in the following commit.

configure: Always apply zlib crc32() rename fix.
PSPP can link against zlib indirectly even if it doesn't link directly, so
it is simplest to always rename gnulib's crc32() to gl_crc32().
