http-client, substitute: Gracefully handle GnuTLS EAGAIN/EINTR.
Partly fixes <https://bugs.gnu.org/47867>.
Reported by Florian Pelz <pelzflorian@pelzflorian.de>.
In GnuTLS up to 3.7.1 included, GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED
are not handled by 'write_to_session_record_port' and could be thrown at
the caller. This patch works around that by dropping connections
altogether and restarting when this happens.
* guix/http-client.scm (false-if-networking-error): Swallow ERROR/AGAIN
and ERROR/INTERRUPTED.
* guix/scripts/substitute.scm (call-with-cached-connection): Likewise.
