abort and assert. It would be cleaner to use NULL or "" here, but gcc

Make use of GEOM Gate direct reads feature. This allows HAST to serve
...
reads with native speed of the underlying provider.
There are three situations when direct reads are not used:
1. Data is being synchronized and synchronization source is the secondary
node, which means secondary node has more recent data and we should read
from it.
2. Local read failed and we have to try to read from the secondary node.
3. Local component is unavailable and all I/O requests are served from the
secondary node.

regardless of whether -F (foreground) option is set or not.
Also, if -P option is specified, ignore pidfile setting from configuration
not only on start but on reload too. This fixes the issue when for hastd
run with -P option reload caused the pidfile change.
