Merge from 10.0-base to 10.0 the feature MDEV-4506: Parallel replication.

Browse Source 
The merge is still missing a few hunks related to temporary tables and
InnoDB log file size. The associated code did not seem to exist in
10.0, so the merge of that needs more work. Until this is fixed, there
are a number of test failures as a result.

@ -41,6 +41,17 @@ The following options may be given as the first argument:
Type of BINLOG_CHECKSUM_ALG. Include checksum for log
events in the binary log. Possible values are NONE and
CRC32; default is NONE.
--binlog-commit-wait-count=#
If non-zero, binlog write will wait at most
binlog_commit_wait_usec microseconds for at least this
many commits to queue up for group commit to the binlog.
This can reduce I/O on the binlog and provide increased
opportunity for parallel apply on the slave, but too high
a value will decrease commit throughput.
--binlog-commit-wait-usec=#
Maximum time, in microseconds, to wait for more commits
to queue up for binlog group commit. Only takes effect if
the value of binlog_commit_wait_count is non-zero.
--binlog-direct-non-transactional-updates
Causes updates to non-transactional engines using
statement format to be written directly to binary log.

--slave-net-timeout=#
Number of seconds to wait for more data from any
master/slave connection before aborting the read
--slave-parallel-max-queued=#
Limit on how much memory SQL threads should use per
parallel replication thread when reading ahead in the
relay log looking for opportunities for parallel
replication. Only used when --slave-parallel-threads > 0.
--slave-parallel-threads=#
If non-zero, number of threads to spawn to apply in
parallel events on the slave that were group-committed on
the master or were logged with GTID in different
replication domains.
--slave-skip-errors=name
Tells the slave thread to continue replication when a
query event returns an error from the provided list
