mysql_discard_or_import_tablespace(): On successful
ALTER TABLE...DISCARD TABLESPACE, evict the table handle from the
table definition cache, so that ha_innobase::close() will be invoked,
like InnoDB expects to be the case. This will avoid an assertion failure
ut_a(table->get_ref_count() == 0) during IMPORT TABLESPACE.
ha_innobase::open(): Do not issue any ER_TABLESPACE_DISCARDED warning.
Member functions for DML will do that.
ha_innobase::truncate(), ha_innobase::check_if_supported_inplace_alter():
Issue ER_TABLESPACE_DISCARDED warnings, to compensate for the removal of
the warning in ha_innobase::open().
row_quiesce_write_indexes(): Only write information about committed
indexes. The ALTER TABLE t NOWAIT ADD INDEX(c) in the nondeterministic
test case will most of the time fail due to a metadata lock (MDL) timeout
and leave behind an uncommitted index.

Some builders in our CI, most notably FreeBSD and IBM AIX, do not support
sparse files. Also, Microsoft Windows requires special means for creating
sparse files. Since these platforms do not run ./mtr --big-test, we will
for now simply move the test to a separate file that requires that option.
- Information_schema.innodb_tablespaces_encryption should print
undo tablespace name as innodb_undo001, innodb_undo002 and soon.
- Encryption test should include undo tablespaces count when
the tests are waiting for the condition to check whether all
tables are encrypted or decrypted.
recv_log_recover_10_4(): Widen the operand of bitwise and to 64 bits,
so that the upgrade check will work when the redo log record is located
more than 4 gigabytes from the start of the first file.
The log overwrite warnings are not being reliably emitted in all
debug-instrumented environments. It may be related to the
scheduling of some InnoDB internal activity, such as the purging
of committed transaction history.
The InnoDB write-ahead log ib_logfile0 is of fixed size,
specified by innodb_log_file_size. If the tail of the log
manages to overwrite the head (latest checkpoint) of the log,
crash recovery will be broken.
Let us clarify the messages about this, including adding
a message on the completion of a log checkpoint that notes
that the dangerous situation is over.
To reproduce the dangerous scenario, we will introduce the
debug injection label ib_log_checkpoint_avoid_hard, which will
avoid log checkpoints even harder than the previous
ib_log_checkpoint_avoid.
log_t::overwrite_warned: The first known dangerous log sequence number.
Set in log_close() and cleared in log_write_checkpoint_info(),
which will output a "Crash recovery was broken" message.
Per fsp0types.h, SDI is on tablespace flags position 14 where MariaDB
stores its pagesize. Flag at position 13, also in MariaDB pagesize
flags, is a MySQL encryption flag.
These are checked only if fsp_flags_is_valid fails, so valid MariaDB
pages sizes don't become errors.
The error message "Cannot reset LSNs in table" was rather specific and
not always true to replaced with more generic error.
ALTER TABLE tbl IMPORT TABLESPACE now reports Unsupported on MySQL
tablespace (rather than index corrupted) along with a server error
message.
MySQL innodb Errors are with with UNSUPPORTED rather than CORRUPTED
to avoid user anxiety.

To prevent ASAN heap-use-after-poison in the MDEV-16549 part of
./mtr --repeat=6 main.derived
the initialization of Name_resolution_context was cleaned up.
