row_sel_get_clust_rec_for_mysql(): Look up the page from the
buffer pool, similar to how MySQL 5.7 does it.

debug_key_management
encrypt_and_grep
innodb_encryption

If real table count is different from what is expected by the test, it
just hangs on waiting to fulfill hardcoded number. And then exits with
**failed** after 10 minutes of wait: quite unfriendly and hard to
figure out what's going on.

Fix and enable some of the tests; some remain disabled.

The tests innodb_gis.rtree_old and innodb_gis.row_format
duplicated some versions of the test main.gis-rtree.
Instead of duplicating, source that test, in a new test
innodb_gis.innodb_gis_rtree.

Introduce innodb_row_format.combinations. Due to this,
ROW_FORMAT=COMPRESSED will not be covered in some tests
where it is covered in MySQL 5.7.

The function rtr_update_mbr_field_in_place() is generating
MLOG_REC_UPDATE_IN_PLACE or MLOG_COMP_REC_UPDATE_IN_PLACE records
on non-leaf pages, even though MLOG_WRITE_STRING would perfectly
suffice for updating a fixed-length data field.

btr_cur_parse_update_in_place(): If flags==7, the record may be
from rtr_update_mbr_field_in_place(), and we must check if the
page is a leaf page. Otherwise, assume that it is.

btr_cur_update_in_place(): Assert that the page is a leaf page.

Other things, mainly to get
create_mysqld_error_find_printf_error tool to work:

- Added protection to not include mysqld_error.h twice
- Include "unireg.h" instead of "mysqld_error.h" in server
- Added protection if ER_XX messages are already defined
- Removed wrong calls to my_error(ER_OUTOFMEMORY) as
  my_malloc() and my_alloc will do this automatically
- Added missing %s to ER_DUP_QUERY_NAME
- Removed old and wrong calls to my_strerror() when using
  MY_ERROR_ON_RENAME (wrong merge)
- Fixed deadlock error message from Galera. Before the extra
  information given to ER_LOCK_DEADLOCK was missing because
  ER_LOCK_DEADLOCK doesn't provide any extra information.

I kept #ifdef mysqld_error_find_printf_error_used in sql_acl.h
to make it easy to do this kind of check again in the future

trx_undo_page_report_rename(): Return a pointer to the start of the
undo log record, not to the start of the (not yet written) next free
record. The wrong return value would sometimes cause ROLLBACK to crash
in an assertion failure (trying to parse garbage from the free area at
the end of the insert_undo log page) if the TRX_UNDO_RENAME_TABLE record
was the very last thing that was written to the insert_undo log. This
would occasionally happen when an ALTER TABLE operation is rolled
back due to invalid FOREIGN KEY constraints in the innodb.innodb test.
In these tests, the error ER_ERROR_ON_RENAME (1025) would be returned
at the end of the ALGORITHM=COPY operation of ALTER TABLE.

trx_undo_page_report_modify(): For SPATIAL INDEX, keep logging
updated off-page columns twice, so that
the minimum bounding rectangle (MBR) will be logged.
Avoiding the redundant logging would require larger changes
to the undo log format.

row_build_index_entry_low(): Handle SPATIAL_UNKNOWN more robustly,
by refusing to purge the record from the spatial index.
We can get this code when processing old undo log from 10.2.10 or
10.2.11 (the releases affected by MDEV-14799, which was a regression
from MDEV-14051).

The InnoDB background tasks can modify tables while LOCK TABLES...WRITE
is in effect. The purge of InnoDB history always worked like this in
MariaDB, but in MySQL 5.7 it sometimes yields to LOCK TABLES.

Also, make gcol.innodb_virtual_index run the purge for an UPDATE
before DROP TABLE is executed.

- The fix in mf_iocache2.c was just to fix a compiler warning

This is to be able to better track where things goes wrong

Make rpl_ctype_latin1 more portable by printing names in hex
Also only run if lower_case_table_names is 0, as this affects the result

up fix for MDEV-12458

trx_undo_rec_get_partial_row(): When the PRIMARY KEY includes a
column prefix of an externally stored column, the already parsed
part of the undo log record may contain a reference to
an off-page column. This is the case in the bug58912 test in
innodb.innodb.

This is a regression caused by MDEV-14051 'Undo log record is too big.'

Purge in the secondary index is wrongly skipped in
row_purge_upd_exist_or_extern() because node->row only does not contain all
indexed columns.

trx_undo_rec_get_partial_row(): Add the parameter for node->update
so that the updated columns will be copied from the initial part
of the undo log record.

- openssl_1 errors where system dependent
- Used not portable UINT32_MAX instead of UINT_MAX32
