libblock: Add RTEMS_BDBUF_USE_PTHREAD
Use the PTHREAD mutexes and condition variables if available. This
helps on SMP configurations to avoid the home grown condition variables
via disabled preemption.
If the bdbufs work better with this pthread implementation, should we
just get rid of the old code in favor of the new code using
pthread_mutex and condvar? This would mean requiring users who want
bdbufs to also configure for POSIX, which I'm not sure whether that is
a problem or not...
I also agree. It seems normal to me to have POSIX enabled to use a POSIX
compliant file system.
I think we need to understand the benefit and trade off the
--enable-posix option gives us these days. The fewer options like this
we have the better our testing results are. There is a limited number of
options we can support before the ability to test becomes impossible. We
have too many to test now.
