Log Message:
use fetch_*() for I/O with SMALLPROG / !WITH_SSL builds

Adapt the SMALLPROG / -UWITH_SSL build to also use the fetch_*()
methods from ssl.c, instead of using stdio, as stdio isn't robust
when using interruptable signals.

Disable ssl-specific support in the fetch_*() methods if WITH_SSL
isn't defined, so SMALLPROG still doesn't have ssl support (as expected).

The resulting SMALLPROG binary is slightly larger than before
(e.g., 157KiB vs 153KiB on amd64).

Set version to 20210603 for this fix and the SO_KEEPALIVE fix for PR 56129.
