buf_flush_write_block_low(): Acquire the tablespace reference once,
and pass it to lower-level functions. This is only a start; further
calls may be removed later.

fil_crypt_thread(): Do invoke fil_crypt_complete_rotate_space()
when the tablespace is about to be dropped. Also, remove a redundant
check whether rotate_thread_t::space is NULL. It can only become
NULL when fil_crypt_find_space_to_rotate() returns false, and in
that case we would already have terminated the loop.

fil_crypt_find_page_to_rotate(): Remove a redundant check for
space->crypt_data == NULL. Once encryption metadata has been
created for a tablespace, it cannot be removed without dropping
the entire tablespace.

This reduces the number of compilation warnings on Windows.

On 64-bit Windows, sizeof(ulint)!=sizeof(ulong).

On 64-bit Windows, sizeof(ulint)!=sizeof(ulong).

This reverts part of commit 50eb40a2
which backported the code from MariaDB 10.2. The XtraDB version of
the code included a ut_error statement (aborting the process) when
a tablespace is not found. Luckily this change was not part of a
release; MariaDB 10.1.22 had been released some days earlier.

This is a reduced version of an originally much larger patch.
We will keep the definition of the ulint, lint data types unchanged,
and we will not be replacing fprintf() calls with ib_logf().

On Windows, use the standard format strings instead of nonstandard
extensions.

This patch fixes some errors in format strings.
Most notably, an IMPORT TABLESPACE error message in InnoDB was
displaying the number of columns instead of the mismatching flags.

Allow 64-bit atomic operations on 32-bit systems,
only relying on HAVE_ATOMIC_BUILTINS_64, disregarding
the width of the register file.

Define UNIV_WORD_SIZE correctly on all systems, including Windows.
In MariaDB 10.0 and 10.1, it was incorrectly defined as 4 on
64-bit Windows.

Define HAVE_ATOMIC_BUILTINS_64 on Windows
(64-bit atomics are available on both 32-bit and 64-bit Windows
platforms; the operations were unnecessarily disabled even on
64-bit Windows).

MONITOR_OS_PENDING_READS, MONITOR_OS_PENDING_WRITES: Enable by default.

os_file_n_pending_preads, os_file_n_pending_pwrites,
os_n_pending_reads, os_n_pending_writes: Remove.
Use the monitor counters instead.

os_file_count_mutex: Remove. On a system that does not support
64-bit atomics, monitor_mutex will be used instead.

Disable the output that was added in MDEV-6812 if log_warnings=2 or less.
Also, remove some redundant messages.

TODO: Implement MDEV-12512 to supercede MDEV-6812 and properly report
the progress of ALTER TABLE…ALGORITHM=INPLACE.

MDEV-11201: gtid_ignore_duplicates incorrectly ignores statements when GTID replication is not enabled

When master_use_gtid=no, the IO thread loads the slave GTID state from
the master during connect. This races with the SQL thread when
gtid_ignore_duplicates=1. If an event is in the relay log from before
the new connect and has not been applied yet, moving the slave
position causes the SQL thread to think that event should be skipped
due to gtid_ignore_duplicates=1.

This patch simply disables gtid_ignore_duplicates when not using GTID,
which seems to be what one would expect.

This is to be friendly to our OSX users where
the libtool path is very different.

Patch credit Jan

It is assumed that both insert..select statements take so
long that drop database from node2 gets to abort them both
but on fast machines it was too small. Increased the size
of insert.

Fixes wsrep_replay_transaction so that it preserves affected rows,
last insert id, and message from diagnostics area.

Introduced a new wsrep_trx_print_locking() which may be called
under lock_sys->mutex if the trx has locks.
