Also, implement MDEV-11027 a little differently from 5.5:

recv_sys_t::report(ib_time_t): Determine whether progress should
be reported.

recv_apply_hashed_log_recs(): Rename the parameter to last_batch.

This is essentially a backport of the 10.0
commit 203f4d41
that fixes a bug and silences a GCC 6.3.0 warning
about a left shift of a signed integer.

Missing parenthesis in a macro definition caused wrong operation
in the Query_cache::send_result_to_client() statement
   thd->query_plan_flags= (thd->query_plan_flags & ~QPLAN_QC_NO) | QPLAN_QC;

This would expand to
   thd->query_plan_flags= (thd->query_plan_flags & ~1) << 6 | 1 << 5;

which would shift the flags by 6 and clear an unrelated flag, instead
of clearing the flag (1 << 6).

Provide more useful progress reporting of crash recovery.

recv_sys_t::progress_time: The time of the last report.

recv_scan_print_counter: Remove.

log_group_read_log_seg(): After after each I/O request,
report progress if needed.

recv_apply_hashed_log_recs(): At the start of each batch,
if there are pages to be recovered, issue a message.

The C++ standard does not allow references to be NULL.
Assign the return value of THD::alloc() to a pointer,
not to a reference.

        Server audit plugin version updated.

This reverts commit fa59ac50.

dir_per_db_rename_to_nenexisting_schema: mysqltest fails with no output
percona_kill_idle_trx_tokudb: MariaDB doesn't support kill_idle_trx var
for all SE.

Probably the result is due to a bug fixed on their server. Restoring old
behaviour for now.

TokuDB testsuite makes use of includes not found in our default 10.0.
Cherry pick them from Percona Server's include directory.

Disabling the cond guards during the creation of Tricond Item for
constant and NULL left expression items

my_readline can fail due to missing file. Make my_readline report this
condition separately so that we can catch it and report an appropriate
error message to the user.

The function posix_fallocate() as well as the Linux system call
fallocate() can return EINTR when the operation was interrupted
by a signal. In that case, keep retrying the operation, except
if InnoDB shutdown has been initiated.

For the same reason as removing binlog rotation on Debian.

Rotating binary/relay logs can cause interuption to the processing
on the server. Binary and relay logs have their own mechanism already
for not getting out of control (expire_logs_days).

By no longer rotating binary and relay logs log rotation is limited to
the following logs:
* error log
* general log
* slow query log

Writing these to the binary log would cause any logrotation on the
slave to occur twice, once due to this and another due to the log-
rotate script on the slave. Now --local is passed to mysqladmin to
prevent this duplication.

Add the following options to mysqladmin

+  flush-binary-log        Flush binary log
+  flush-engine-log        Flush engine log(s)
+  flush-error-log         Flush error log
+  flush-general-log       Flush general log
+  flush-relay-log         Flush relay log
+  flush-user-resources    Flush user resources

Due to the way Advance Toolchain before 10.0-3 and 8.0-8 is
packaged, shared libraries installed after the library cache
advance-toolchain-atX.Y-runtime package aren't updated in
/opt/atX.Y/etc/ld.so.cache. This results in mysqld,
configured with RUNPATH set to /opt/atX.Y/lib64, resulting
in the Advance Toolchain loader being used and if libraries
such as jemalloc, libssl or any other library that mysqld uses
is installed after Advance Toolchain, these libraries aren't in
the cache and therefore won't be found in the RPM postinstall
when mysqld is executed by mysql_install_db.

This is an addition to original fix. Buildbot revealed another sporadic failure
in perfschema.threads_mysql test. Tests relies on data stored in
performance_schema.threads, while performing waits on
information_schema.processlist. These tables are not updated synchronously.

Fixed by performing waits on performance_schema.threads instead.

Applied lost in a merge revision 7f38a070:

MDEV-10043 - main.events_restart fails sporadically in buildbot (crashes upon
             shutdown)

There was race condition between shutdown thread and event worker threads.

Shutdown thread waits for thread_count to become 0 in close_connections(). It
may happen so that event worker thread was started but didn't increment
thread_count by this time. In this case shutdown thread may miss wait for this
working thread and continue deinitialization. Worker thread in turn may continue
execution and crash on deinitialized data.

Fixed by incrementing thread_count before thread is actually created like it is
done for connection threads.

Also let event scheduler not to inc/dec running threads counter for symmetry
with other "service" threads.

MDEV-9635: Server crashes in part_of_refkey  or assertion `!created && key_to_save < (int)s->keys' failed in TABLE::use_index(int) or with join_cache_level>2

Do not try to create index where ref is for hash join.

On FreeBSD liblz4 is installed in /usr/local/lib.
Groonga uses pkg_check_modules to check for liblz4 (that is, pkg-config),
and then it used to set for libgroonga.a

  link_directories({$LIBLZ4_LIBRARY_DIRS})
  target_link_libraries(... ${LIBLZ4_LIBRARIES})

Now groonga is a static library, linked into ha_mroonga.so. CMake won't
link dynamic liblz4.so into libgroonga.a, instead it'll pass it as a
dependency and will link it into ha_mroonga.so. Fine so far. But it will
not pass link_directories from the static library as a dependency,
so ha_mroonga.so won't find liblz4.so

As suggested on cmake mailing list (e.g.
here: http://public.kitware.com/pipermail/cmake/2011-November/047468.html)
we switch to use the full path to liblz4.so, instead of the -l/-L pair.
