This series moves the timeout parameter, that is passed to most
f_m_r methods, into the reader_permit. This eliminates
the need to pass the timeout around, as it's taken
from the permit when needed.
The permit timeout is updated in certain cases
when the permit/reader is paused and retrieved
later on for reuse.
Following are perf_simple_query results showing ~1%
reduction in insns/op and corresponding increase in tps.
