Import wiredtiger: 6173a98979715ed727c432c1a31da64ea8a37048 from branch mongodb-3.6

ref: ff10db8811..6173a98979
for: 3.5.11

WT-3039       Enhance logging so new log files no longer need to wait for the previous log file to be synced
WT-3138       Enhance eviction statistics
WT-3140       Enhance json mode statistics to better support per-dhandle statistics
WT-3310       Add support to WT_SESSION::alter to change table log setting
WT-3329       With a uniform workload and a number of small collections, eviction does a poor job of selecting candidates for eviction.
WT-3381       Improve concurrency in the transaction subsystem
WT-3394       Build WiredTiger with gcc7
WT-3396       test/csuite/wt3363_checkpoint_op_races, test_utility cleanups
WT-3397       Coverity lint
WT-3398       in-memory configurations don't support schema_worker operations
WT-3401       Lint and minor cleanup
WT-3402       Move cached overflow records to the update list.
WT-3403       Automated tests timeout running csuite
WT-3409       WiredTiger generations can silently self-deadlock.
WT-3413       Add more aggressive compile warning flags to Jenkins Windows job
WT-3415       setting timestamp in txn_state requires the global write lock
WT-3421       Compilation error unreachable code in test/csuite/wt3363_checkpoint_op_races
WT-3424       additional gcc 7.1 compile warnings.
WT-3425       workgen: add ability to reopen cursors
WT-3426       Add new wtperf configuration to automated performance testing
WT-3438       Don't tune eviction thread count when the count is fixed

Also explicitly disable v2 log records via a configuration setting in MongoDB -
this will later be plumbed into the feature compatability version mechanism.
