85a2b58987
Fixes <https://bugs.gnu.org/28784>.
This mostly reverts 81a0f1cdf1, which
introduced a regression: revealed ports are *never* GC'd (contrary to
what Guile's manual suggests).
In addition to the revert, 'close-procedure' now explicitly swallows
EBADF errors when 'close-port' is called.
* guix/zlib.scm (close-procedure): New procedure.
(make-gzip-input-port)[gzfile]: Use 'fileno' instead of 'port->fdes'.
Use 'close-procedure' instead of 'gzclose'.
(make-gzip-output-port): Likewise.
* tests/zlib.scm ("compression/decompression pipe"): Use 'port-closed?'
to determine whether PARENT has been closed.
