c66ee1b31e 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.

7f995f6907 If hastd is invoked with "-P pidfile" option always create pidfile
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.

f737157838 If a local write request is from the synchronization thread, when it
is synchronizing data that is out of date on the local component, we
should not send G_GATE_CMD_DONE acknowledge to the kernel.

This fixes the issue, observed in async mode, when on synchronization
from the remote component the worker terminated with "G_GATE_CMD_DONE
failed" error.

518dd4c0d9 After every activemap change flush disk's write cache, so that write
reordering won't make the actual write to be committed before marking
the coresponding extent as dirty.

It can be disabled in configuration file.

If BIO_FLUSH is not supported by the underlying file system we log a warning
and never send BIO_FLUSH again to that GEOM provider.
