core: allow changing TCP keepalive packet idle time using `tcp-keepalive` command-line option or config-file option.
...
This may be useful in certain scenarios. However, server load from keepalive
is increased 6-fold if code is hard-changed from 30 to 5. So, provide it as
an option instead, and use the previous value as a default (30).
Explanation from
015c064396
Kevin's middlecoin fix, CURL TCP keepalive constants lowered:
CURLOPT_TCP_KEEPIDLE from 45 to 5 and CURLOPT_TCP_KEEPINTVL from 30 to
5. Before it'd trigger a keepalive packet after 45 seconds of connection
idle time and then again every 30 seconds. Now it triggers a keepalive
packet after 5 seconds of connection idle time and then again every 5
seconds.
It makes the client more resilient against coin switching pools or just
pools with connection issues in general. It will however add a tiny bit
pressure to the pool server; but a TCP keepalive probe is only about
60-80 bytes, so I don't think it is an issue.

adl: Fix query of default fan speed
...
This fixes a crash of the AMD driver when quitting as we were trying
to apply what basically is an uninitialized value.
Adds additional code to cope with a failure to retrieve just in case
we hit another problem like that in the future.
