Revert Bug #25175249  ASSERTION: (TEMPL->IS_VIRTUAL && !FIELD) || (FIELD && FIELD->PREFIX_LEN ? FIELD

We don't want this in innodb/xtradb

* CMakeLists.txt erroneous duplicated lines.
* Unneded differences in tabjson.cpp
* Unneded space differences in jdbconn.{cpp|h}

This is a squashed merge.

Another fix (work around MDEV-12699): Ensure that the 1234-byte
truncated page is all zero, so that after data file extension
pads the page with zeroes to full page size, the page will read
as a valid one (consisting of zero bytes only).

The purpose of the test is to ensure that redo log apply will
extend data files before applying page-level redo log records.
The test intermittently failed, because the doublewrite buffer
would sometimes contain data for the pages that the test
truncated. When the test truncates data files, it must also remove
the doublewrite buffer entries, because under normal operation, the
doublewrite buffer would only be written to if the data file already
has been extended.

Compilation got confused  about 2 wsrep.h headers in include path

Introduce innodb_encrypt_log.combinations and prove that
the encryption and decryption take place during both
online ADD INDEX (WL#5266) and online table-rebuilding ALTER (WL#6625).

Apply the same changes to both InnoDB and XtraDB.

message was written.

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

MDEV-13807 mariabackup --apply-log-only does generate redo log by performing rollback and possibly other tasks

Skip rollback and other redo-log-generating tasks if
srv_apply_log_only is set.

Instead of assigning the debug variable recv_no_log_write = FALSE,
assign it to srv_apply_log_only, so that any unwanted writes are caught.

The problem was introduced by the patch for MDEV-7661,
which (in addition to the fix itself) included an attempt to make
CONVERT/CAST work in the same way with fields
(i.e. return NULL in strict mode if a non-convertable character found).
It appeared to be a bad idea and some users were affected by this
behavior change. Changing CONVERT/CAST not depend on sql_mode
(restoring pre-10.1.4 behavior).

MDEV-13685 Can not replay binary log due to Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8mb4_general_ci,COERCIBLE) for operation 'concat'

Fixed by removing writing key version to start of every block that
was encrypted. Instead we will use single key version from log_sys
crypt info.

After this MDEV also blocks writen to row log are encrypted and blocks
read from row log aren decrypted if encryption is configured for the
table.

innodb_status_variables[], struct srv_stats_t
	Added status variables for merge block and row log block
	encryption and decryption amounts.

Removed ROW_MERGE_RESERVE_SIZE define.

row_merge_fts_doc_tokenize
	Remove ROW_MERGE_RESERVE_SIZE

row_log_t
	Add index, crypt_tail, crypt_head to be used in case of
	encryption.

row_log_online_op, row_log_table_close_func
	Before writing a block encrypt it if encryption is enabled

row_log_table_apply_ops, row_log_apply_ops
	After reading a block decrypt it if encryption is enabled

row_log_allocate
	Allocate temporary buffers crypt_head and crypt_tail
	if needed.

row_log_free
	Free temporary buffers crypt_head and crypt_tail if they
	exist.

row_merge_encrypt_buf, row_merge_decrypt_buf
	Removed.

row_merge_buf_create, row_merge_buf_write
	Remove ROW_MERGE_RESERVE_SIZE

row_merge_build_indexes
	Allocate temporary buffer used in decryption and encryption
	if needed.

log_tmp_blocks_crypt, log_tmp_block_encrypt, log_temp_block_decrypt
	New functions used in block encryption and decryption

log_tmp_is_encrypted
	New function to check is encryption enabled.

Added test case innodb-rowlog to force creating a row log and
verify that operations are done using introduced status
variables.

- 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

recv_reset_logs(): Initialize the redo log buffer, so that no data
from the old redo log can be written to the new redo log.

This bug has very little impact before MariaDB 10.2. The
innodb_log_encrypt option that was introduced in MariaDB 10.1
increases the impact. If the redo log used to be encrypted, and
it is being resized and encryption disabled, then previously
encrypted data could end up being written to the new redo log
in clear text. This resulted in encryption.innodb_encrypt_log
test failures in MariaDB 10.2.
