This reverts commit d39629f0.

Because running mtr for many hours with no output whatsoever
is not really what we should do.

And in 5.5 `make test` just works anyway, nothing to fix here.

MDEV-16534 PPC64: Unexpected error with a negative value into auto-increment columns in HEAP, MyISAM, ARIA

Revert 7bbe324f
Fix the bug differently (in log_event.cc)
Fix the test case to actually fail without the bug fix

In this case we are accessing incorrect memory when we have mergeable semi-joins.
In the case when we have mergeable semi joins parent select will have a table count
of all the tables in that select plus all the tables involved in the IN-subquery.
But this table count does not include the "sjm table" (only includes the inner and outer tables)
denotes as <subquery#> in explain.

* xtrabackup no longer support --compact
* wsrep_sst_mysqldump wasn't always using --default-file
* wsrep_sst.cc overquoted --default-file for wsrep_sst_mysqldump

also remove redundant lines config and test lines, compiler warnings,
and mark big tests as big.

message:

MDEV-15611 Due to the failure of foreign key detection, Galera...
slave node killed himself.

Problem:- If we try to delete table with foreign key and table whom it is
referring with wsrep_slave_threads>1 then galera tries to execute both
Delete_rows_log-event in parallel, which should not happen.

Solution:- This is happening because we do not have foreign key info in
write set. Upto version 10.2.7 it used to work fine. Actually it happening
because of issue in commit 2f342c45. wsrep_must_process_fk should be used
with negation.

note that ${A#foo} is $A if there's no prefix foo. That's why
galera nodes tried to connect to 127.0.0.1:127.0.0.1 if there was
no port in the address

fil_page_decompress(): Replaces fil_decompress_page().
Allow the caller detect errors. Remove
duplicated code. Use the "safe" instead of "fast" variants of

The length of the input buffer always was srv_page_size (innodb_page_size).
Remove printouts, and remove the fil_space_t* parameter.

buf_tmp_buffer_t::reserved: Make private; the accessors acquire()
and release() will use atomic memory access.

buf_pool_reserve_tmp_slot(): Make static. Remove the second parameter.
Do not acquire any mutex. Remove the allocation of the buffers.

buf_tmp_reserve_crypt_buf(), buf_tmp_reserve_compression_buf():
Refactored away from buf_pool_reserve_tmp_slot().

buf_page_decrypt_after_read(): Make static, and simplify the logic.
Use the encryption buffer also for decompressing.

buf_page_io_complete(), buf_dblwr_process(): Check more failures.

fil_space_encrypt(): Simplify the debug checks.

fil_space_t::printed_compression_failure: Remove.

fil_get_compression_alg_name(): Remove.

fil_iterate(): Allocate a buffer for compression and decompression
only once, instead of allocating and freeing it for every page
that uses compression, during IMPORT TABLESPACE.

fil_node_get_space_id(), fil_page_is_index_page(),
fil_page_is_lzo_compressed(): Remove (unused code).

make it return the same Info values as for the standalone server.

This fixes plugins.processlist for --embedded

make thd_get_error_context_description() to show not just
thd->proc_info, but exactly the same thread state that SHOW PROCESSLIST
shows.

buf_page_check_corrupt(): Display the file name.

MariaDB never supported the MySQL 5.7 compression format.

FIL_PAGE_TYPE_COMPRESSED: Remove. This was originally added
as FIL_PAGE_COMPRESSED.

Correctly port 09b25f85 from 10.0.

Expose check_is_super via include file to allow wsrep_on_check to use
it.

Pull rename_table test-fix from 10.0

An embedded run will output the full path name instead of a relative
one. Update results to cover both cases.

           specific temporary errors

The optimistic parallel slave's worker thread could face a run-time error due to
the algorithm's specifics which allows for conflicts like the reported
"Can't find record in 'table'".
A typical stack is like

Here {{handler::print_error}} computes whether to error log the
current error when --log-warnings > 1. The decision flag is consulted
bu {{my_message_sql()}} which can be eventually called.
In the bug case the decision is to log.
However in the optimistic mode slave applier case any conflict is
attempted to resolve with rollback and retry to success. Hence the
logging is at least extraneous.

The case is fixed with adding a new flag {{ME_LOG_AS_WARN}} which
{{handler::print_error}} may propagate further on through {{my_error}}
when the error comes from an optimistically running slave worker thread.

The new flag effectively requests the warning level for the errlog record,
while the thread's DA records the actual error (which is regarded as temporary one
by the parallel slave error handler).

Check the name of the primary key to be 'PRIMARY'. Than
differs it from any implicit primary keys created by an engine.

When attempting to rename a table to a non-existing database,
InnoDB would misleadingly report "OS error 71" when in fact the
error code is InnoDB's own (OS_FILE_NOT_FOUND), and not report
both pathnames. Errors on rename could occur due to reasons
connected to either pathname.

os_file_handle_rename_error(): New function, to report errors in
renaming files.

Backporting (partially) the fix for MDEV-14603.

Added unregistering writers in case of log error.
Added more debugging control about adding/removing writers to the buffers.
