- the probably ultimate fix for dependencies on VS
- remove some GET_TARGET_PROPERTY(LOCATION ...), they are deprecated in
cmake 3.9
- simplify signing targets on Windows.
- remove INSTALL_DEBUG_TARGET, we do not mix binaries from different builds
in the same package

The messages are getting lost because they are written with fprintf()
but without fflush(), so abort() would lose buffered text.
Applied fix from 10.2, which makes in_logf() use
sql_print_information(), which in turn does proper flush after each message

innodb_encrypt_log startup
This fixes several InnoDB bugs related to innodb_encrypt_log and
two Mariabackup --backup bugs.
log_crypt(): Properly derive the initialization vector from the
start LSN of each block. Add a debug assertion.
log_crypt_init(): Note that the function should only be used when
creating redo log files and that the information is persisted in
the checkpoint pages.
xtrabackup_copy_log(): Validate data_len.
xtrabackup_backup_func(): Always use the chosen checkpoint buffer.
log_group_write_buf(), log_write_up_to(): Only log_crypt() the redo
log payload, not the padding bytes.
innobase_start_or_create_for_mysql(): Do not invoke log_crypt_init()
or initiate a redo log checkpoint.
recv_find_max_checkpoint(): Return the contents of LOG_CHECKPOINT_NO
to xtrabackup_backup_func() in log_sys->next_checkpoint_no.

Implement lock-ddl-per-table option that locks tables before it
is copied to backup, and helds the lock until backup finished
The "DDL-lock" itself is implemented as "SELECT * from <table> LIMIT 0",
inside a transaction, and "COMMIT" of this transaction is the DDL-unlock.

Fixes also MDEV-13488: InnoDB writes CRYPT_INFO even though
encryption is not enabled.
Fixes also MDEV-13093: Leak of Datafile::m_crypt_info on
shutdown after failed startup.
Problem was that we created encryption metadata (crypt_data) for
system tablespace even when no encryption was enabled and too early.
System tablespace can be encrypted only using key rotation.
Test innodb-key-rotation-disable, innodb_encryption, innodb_lotoftables
require adjustment because INFORMATION_SCHEMA INNODB_TABLESPACES_ENCRYPTION
contain row only if tablespace really has encryption metadata.
xb_load_single_table_tablespace(): Do not call
fil_space_destroy_crypt_data() any more, because Datafile::m_crypt_data
has been removed.
fil_crypt_realloc_iops(): Avoid divide by zero.
fil_crypt_set_thread_cnt(): Set fil_crypt_threads_event if
encryption threads exist. This is required to find tablespaces
requiring key rotation if no other changes happen.
fil_crypt_find_space_to_rotate(): Decrease the amount of time waiting
when nothing happens to better enable key rotation on startup.
fil_ibd_open(), fil_ibd_load(): Load possible crypt_data from first
page.
class Datafile, class SysTablespace : remove m_crypt_info field.
Datafile::get_first_page(): Return a pointer to first page buffer.
fsp_header_init(): Write encryption metadata to page 0 only if
tablespace is encrypted or encryption is disabled by table option.
i_s_dict_fill_tablespaces_encryption(): Skip tablespaces that do not
contain encryption metadata. This is required to avoid too early
wait condition trigger in encrypted -> unencrypted state transfer.

The test mariabackup.incremental_backup revealed a memory leak
in have_queries_to_wait_for(). The problem is that
xb_mysql_query() is being invoked with bool use_result=true
but the result is not being freed by mysql_store_result().
There are similar leaks in other functions.
have_queries_to_wait_for(): Invoke mysql_free_result() to
clean up after the mysql_store_result() that was invoked
by xb_mysql_query().
select_incremental_lsn_from_history(): Plug the leak on failure.
kill_long_queries(): Plug the memory leak.

The fix broke mariabackup --prepare --incremental.
The restore of an incremental backup starts up (parts of) InnoDB twice.
First, all data files are discovered for applying .delta files. Then,
after the .delta files have been applied, InnoDB will be restarted
more completely, so that the redo log records will be applied via the
buffer pool.
During the first startup, the buffer pool is not initialized, and thus
trx_rseg_get_n_undo_tablespaces() must not be invoked. The apply of
the .delta files will currently assume that the --innodb-undo-tablespaces
option correctly specifies the number of undo tablespace files, just
like --backup does.
The second InnoDB startup of --prepare for applying the redo log will
properly invoke trx_rseg_get_n_undo_tablespaces().
enum srv_operation_mode: Add SRV_OPERATION_RESTORE_DELTA for
distinguishing the apply of .delta files from SRV_OPERATION_RESTORE.
srv_undo_tablespaces_init(): In mariabackup --prepare --incremental,
in the initial SRV_OPERATION_RESTORE_DELTA phase, do not invoke
trx_rseg_get_n_undo_tablespaces() because the buffer pool or the
redo logs are not available. Instead, blindly rely on the parameter
--innodb-undo-tablespaces.

InnoDB I/O and buffer pool interfaces and the redo log format
have been changed between MariaDB 10.1 and 10.2, and the backup
code has to be adjusted accordingly.
The code has been simplified, and many memory leaks have been fixed.
Instead of the file name xtrabackup_logfile, the file name ib_logfile0
is being used for the copy of the redo log. Unnecessary InnoDB startup and
shutdown and some unnecessary threads have been removed.
Some help was provided by Vladislav Vaintroub.
Parameters have been cleaned up and aligned with those of MariaDB 10.2.
The --dbug option has been added, so that in debug builds,
--dbug=d,ib_log can be specified to enable diagnostic messages
for processing redo log entries.
By default, innodb_doublewrite=OFF, so that --prepare works faster.
If more crash-safety for --prepare is needed, double buffering
can be enabled.
The parameter innodb_log_checksums=OFF can be used to ignore redo log
checksums in --backup.
Some messages have been cleaned up.
Unless --export is specified, Mariabackup will not deal with undo log.
The InnoDB mini-transaction redo log is not only about user-level
transactions; it is actually about mini-transactions. To avoid confusion,
call it the redo log, not transaction log.
We disable any undo log processing in --prepare.
Because MariaDB 10.2 supports indexed virtual columns, the
undo log processing would need to be able to evaluate virtual column
expressions. To reduce the amount of code dependencies, we will not
process any undo log in prepare.
This means that the --export option must be disabled for now.
This also means that the following options are redundant
and have been removed:
xtrabackup --apply-log-only
innobackupex --redo-only
In addition to disabling any undo log processing, we will disable any
further changes to data pages during --prepare, including the change
buffer merge. This means that restoring incremental backups should
reliably work even when change buffering is being used on the server.
Because of this, preparing a backup will not generate any further
redo log, and the redo log file can be safely deleted. (If the
--export option is enabled in the future, it must generate redo log
when processing undo logs and buffered changes.)
In --prepare, we cannot easily know if a partial backup was used,
especially when restoring a series of incremental backups. So, we
simply warn about any missing files, and ignore the redo log for them.
FIXME: Enable the --export option.
FIXME: Improve the handling of the MLOG_INDEX_LOAD record, and write
a test that initiates a backup while an ALGORITHM=INPLACE operation
is creating indexes or rebuilding a table. An error should be detected
when preparing the backup.
FIXME: In --incremental --prepare, xtrabackup_apply_delta() should
ensure that if FSP_SIZE is modified, the file size will be adjusted
accordingly.

This will also change the minimum and maximum value of

The option was basically duplicating InnoDB functionality.

These functions cannot possibly work in MariaDB 10.2, and it is
uncertain if they really work in 10.1 either.

innodb_data_file_path=ibdata1:3M;
Problem was that FIL_PAGE_FLUSH_LSN_OR_KEY_VERSION field that for
encrypted pages even in system datafiles should contain key_version
except very first page (0:0) is after encryption overwritten with
flush lsn.
Ported WL#7990 Repurpose FIL_PAGE_FLUSH_LSN to 10.1
The field FIL_PAGE_FLUSH_LSN_OR_KEY_VERSION is consulted during
InnoDB startup.
At startup, InnoDB reads the FIL_PAGE_FLUSH_LSN_OR_KEY_VERSION
from the first page of each file in the InnoDB system tablespace.
If there are multiple files, the minimum and maximum LSN can differ.
These numbers are passed to InnoDB startup.
Having the number in other files than the first file of the InnoDB
system tablespace is not providing much additional value. It is
conflicting with other use of the field, such as on InnoDB R-tree
index pages and encryption key_version.
This worklog will stop writing FIL_PAGE_FLUSH_LSN_OR_KEY_VERSION to
other files than the first file of the InnoDB system tablespace
(page number 0:0) when system tablespace is encrypted. If tablespace
is not encrypted we continue writing FIL_PAGE_FLUSH_LSN_OR_KEY_VERSION
to all first pages of system tablespace to avoid unnecessary
warnings on downgrade.

fil_write_flushed_lsn_to_data_files().
Only write to the first page of the system tablespace (page 0:0)
if tablespace is encrypted, or write all first pages of system
tablespace and invoke fil_flush_file_spaces(FIL_TYPE_TABLESPACE)
afterwards.
fil_read_first_page(): read flush_lsn and crypt_data only from
first datafile.
fil_open_single_table_tablespace(): Remove output of LSN, because it
was only valid for the system tablespace and the undo tablespaces, not
user tablespaces.
