[PATCH] Remove check against SVN_HAVE_ZLIB in stream.c

["Hyrum K. Wright" <hy...@byu.edu>]

As of r18363, we now include zlib unconditionally.  The check against
SVN_HAVE_ZLIB in libsvn_subr/stream.c is now redundant, because we are
guaranteed to have zlib available.  This patch removes this check, and
also changes the behavior of svn_stream_compressed to always return the
compressed stream, instead of defaulting to the uncompressed version.

This patch does not remove the SVN_HAVE_ZLIB define, but it would appear
that this is also redundant.
