a0fd1c3abe WT-2316: WT_CURSOR.prev out-of-order returns, fix a split race. 
Increase the cursor movement in format to 100 calls, hopefully that
will increase our exposure to cursor races during splits.

5d0f39b1c9 Clean up error handling around records not being found; if we have an 
open cursor that found the record once, it should find it again, it's
an error if we've lost that record.

1c0ee83087 WT-1967: creating a lookaside table to hold updates which are no longer 
useful, but which still might be required by current readers.

When reconciling pages with updates which still might be read by existing
snapshot readers, write the updates into a lookaside table.  When those
pages are read back into the cache, any still-relevant updates are read
back from the lookaside table and attached to the page.

Add a new on-disk page-header flag, WT_PAGE_LAS_UPDATE, set when a page
has records in the look-aside table.

Remove the __wt_evict_page() code, replace with calls to __wt_evict(),
and add testing in reconciliation to only write committed updates.  As
part of that change, remove the WT_ISO_EVICTION transaction isolation
configuration, it's no longer used (WT_ISO_READ_UNCOMMITTED is used
instead).

Delete the WT_PAGE_MODIFY.rec_max_txn field (no longer needed after
reconciliation is changed to return EBUSY if a page wasn't marked
clean, replacing the test of WT_PAGE_MODIFY.rec_max_txn __evict_review).

Delete the test for all updates being globally visible when a page is
discarded from the cache, that's no longer true. Delete the
WT_SESSION_DISCARD_FORCE flag, used to turn off that check when forcibly
discarding a page.

bb986cf409 Avoid read/write races in the PRNG: switch to using an 8B value instead 
of a two, 4B value array, declare the value volatile to avoid having the
compiler alter the read/write path.

Add a check if a PRNG component ever goes to zero and reset it.

ca7a3de5eb Rework test/format to use the WiredTiger RNG, not rand. 
Give every thread its own RNG state so there's no competition for the
cache lines.

Initialize the random-number generator early so we catch all possible
configuration uses.

Remove duplicates of WiredTiger's macros.

a2fc5559a2 Simplify the operations loop -- basically, we want to do N loops of 
operations so we test opening and closing the objects, but if there
are no operations to do, we just need to verify the bulk-load and
we're done.

Don't drop core & test recovery until the last of the N loops, we
were doing it on the first.

15a98a1cd0 Instead of introducing an additional configuration string (timeout), 
use timer to specify the maximum run, that is, you can set a count
of operations as well as the timer, and if both set, whichever expires
first limits the run.

optionally indirects through a NULL and core dumps, then we verify
the object.
