buf_dblwr_process(): Remove the useless warning that a copy of a page
in the doublewrite buffer is corrupted. We already report an error if a
corrupted page cannot be recovered from the doublewrite buffer.

Note: In MariaDB 10.1, the original bug reported in MDEV-13893 could
still be easily repeatable. In MariaDB 10.2.24, MDEV-12699 should
have reduced the probability considerably.

fts_get_table_name(): Add the parameter bool dict_locked=false.

fts_get_table_name(): Output to a caller-allocated buffer.

fts_get_table_name_prefix(): Use the lower-overhead allocation
ut_malloc() instead of mem_alloc().

This is based on mysql/mysql-server@d1584b9f38ff0bcf609d181db35f74108e022168
in MySQL 5.7.4.

fts_table_t::parent: Remove the redundant field. Refer to
table->name.m_name instead.

fts_update_sync_doc_id(), fts_update_next_doc_id(): Remove
the redundant parameter table_name.

fts_get_table_name_prefix(): Access the dict_table_t::name.
FIXME: Ensure that this access is always covered by
dict_sys->mutex.

fts_state_t, fts_slot_t::state: Remove. Replaced by fts_slot_t::running
and fts_slot_t::table_id as follows.

FTS_STATE_SUSPENDED: Removed (unused).

FTS_STATE_EMPTY: Removed. table_id=0 will denote empty slots.

FTS_STATE_RUNNING: Equivalent to running=true.

FTS_STATE_LOADED, FTS_STATE_DONE: Equivalent to running=false.

fts_slot_t::table: Remove. Tables will be identified by table_id.
After opening a table, we will check fil_table_accessible() before
accessing the data.

fts_optimize_new_table(), fts_optimize_del_table(),
fts_optimize_how_many(), fts_is_sync_needed():
Remove the parameter tables, and use the static variable fts_slots
(which was introduced in MariaDB 10.2) instead.

No functional change.

Call my_timer_init() only once and then reuse it from InnoDB and
perfschema storage engines.

This patch speeds up empty test for me like this:
./mtr -mem innodb.kevg,xtradb  1.21s user 0.84s system 34% cpu 5.999 total
./mtr -mem innodb.kevg,xtradb  1.12s user 0.60s system 31% cpu 5.385 total

The crash happens when writing into log file.
The reason is likely that the call to WriteFile() was missing a valid
parameter for lpNumberOfBytesWritten. This seems only to happen on ancient
version of Windows.

Since the fix to MDEV-16430 in 141bc58a, null pointer was passed
instead of valid pointer.

The fix is to provide a valid lpNumberOfBytesWritten parameter.

A sequel to 9180e866 and 149b7547.

ALTER TABLE ... ADD FOREIGN KEY may crash if parent table is updated
concurrently.

Block FK parent table updates even earlier, before intermediate child
table is created.

Use proper charset info for my_casedn_str() and don't update original
identifiers so that lower_cast_table_names == 2 is honoured.

Fix:
====
1) Combined innodb_ft_result_cache_limit_32.test and
innodb_ft_result_cache_limit_64.test test case in sys_vars suite.

2) Use word_size.inc for combinations of innodb_ft_result_cache_limit test case.

regression after 3db6de33

in RPMs continue creating the $datadir outside of mysql_install_db.
RPMs put the socket in there, so it cannot be chmod 0700.

Test case was not stable. Fixed also galera_parallel_autoinc_manytrx
as it has the same problem.

This reverts commit 8dc670a5.

The symbol sys_timer_info was not being exported correctly,
which caused linking failures on some platforms.

To read histograms for a table, we should check if the allocation of statistics was done or not,
if not done we should not try to read histograms for such a table.

to the patch for MDEV-17605

MDEV-14572: Assertion `! is_set()' failed in Diagnostics_area::set_eof_status upon EXPLAIN UPDATE in PS

Restore EXPAIN flag in SELECT_LEX before execution multi-update by flag in LEX
(the same but in other way made before INSERT/DELETE/SELECT)

Without it, mysql_update() didn't know that there will be EXPLAIN result set and was sending OK at the end of the update, which conflicted with the EOF sent later by EXPLAIN.

The patch for MDEV-18738 fixed this problem. Adding tests only.

copy_if_not_alloced() did not handle situations when
"from" is a constant string pointing to a substring of "to",
so this code part freed "to" but then tried to copy its old (already freed)
content to a new buffer:

  if (to->realloc(from_length))
    return from;
  if ((to->str_length=MY_MIN(from->str_length,from_length)))
    memcpy(to->Ptr,from->Ptr,to->str_length);

Adding a new code piece that catches such constant substrings
and propery reallocs "to" to preserve its important part referenced
by "from".

This problem was earlier fixed, possibly by f8a800be
and is not repeatable in 10.1-10.4 any more. Adding tests only.

if log_warnings > 1.

This makes ER_DBACCESS_DENIED_ERROR handling the same as we do for other
"access denied"

Change error message.

Added a call to X509_check_ip_asc() in case server_hostname represents
an IP address.
