Currently, VB2_DEBUG() will print the function name as a prefix to the
debug output. Add VB2_DEBUG_RAW() to print without that, so that it's
possible to print little bits of debug output. Use this in ec_sync to
hex dump the hashes.
And then clean up all of the debug calls which explicitly did things like:
VB2_DEBUG("%s: foo", __func__);
to just:
VB2_DEBUG("foo");
so they don't double-print the function name
