This happens when doing NEXT VALUE for a temporary table

sequence functions

This happened when trying to do delete a sequence hidden by a temporary
table.
Fixed by ignoring non-sequence temporary tables when trying to drop
sequences.

Fixes two issues:
- Update assert in open_and_process_tables to handle sequences
- Removed not needed and conflicting mdl_context.release_transactional_locks
in sql_sequence.cc. The MDL lock is released at end of
mysql_execute_command().

This happened when trying to PARTITION a SEQUENCE table
Problem was that wrong function was used to get engine name
Signed-off-by: Monty <monty@mariadb.org>
Fixing mysql_execute_command() and store_schema_proc() not to use
stored object type codes TYPE_ENUM_PROCEDURE and TYPE_ENUM_FUNCTION.
Using pointers to Sp_handler instead, to make the code symmetric across
existing (function,procedure) and future (e.g package) SP object types.
The problem was that the code in replication didn't distinguish between a
setval() failing because the stored sequence number was bigger than the
current (should have been ignored) and a failure from the storage engine.
- Renaming sp_rcontext::sp to sp_rcontext:m_sp for consistency
with other sp_rcontext_members, and for consistency with the
same purpose member Item_sp_variable::m_sp.
- Passing a "const sp_head*" pointer to sp_rcontext::sp_rcontext()
and to sp_rcontext::create().
Initializing sp_rcontext::m_sp right in the constructor
instead of having a separate initialization after "new sp_rcontext"
or sp_rcontext::create().
- Adding the "const" qualifier to sp_rcontext::m_sp and Item_sp_variable::m_sp
remove remnants of 10.0 bugfix, incorrectly merged into 10.2
Using col_names[i] was obviously, wrong, must've been col_names[ifield->col_no].
incorrect column name resulted in innodb having index unique_id2(id1),
while the server thought it's unique_id2(id4).
But col_names[ifield->col_no] is wrong too, because `table` has non-renamed
columns, so the correct column name is always dict_table_get_col_name(table, ifield->col_no)
allow to build with the default port number 3306.
Now -DMYSQL_TCP_PORT=# sets the default port name and
-DMYSQL_TCP_PORT_DEFAULT=# sets the magic port=0 behavior,
if it's MYSQL_TCP_PORT_DEFAULT=0 it's enabled, otherwise - disabled.
i_s_sys_tables_fill_table_stats(): Acquire dict_operation_lock
S-latch before acquiring dict_sys->mutex, to prevent the table
from being removed from the data dictionary cache and from
being freed while i_s_dict_fill_sys_tablestats() is accessing
the table handle.
Issue
=====
The original issue was that the size of a fil_per_table tablespace was calculated
incorrectly during truncate in the presence of an fts index. This incorrect calculation
was fixed as part of BUG#25053705 along with a testcase to reproduce the bug. The
assert that was added as part of it to reproduce the bug was wrong and resulted in
this bug.
Fix
===
Although the assert was removed earlier in a seperate commit as it was blocking the
ntest, this patch replaces the other parts of the code that were added to reproduce
the bug and replaces it with code that tries to reproduce the bug in a different way.
The new code basically tries to tweak conditions so as to simulate the random read
where a page that doesn't exist is tried to be read.

The ownership of the field query->intersection usually transfers
to query->doc_ids. In some error scenario, it could be possible
that fts_query_free() would be invoked with query->intersection!=NULL.
Let us handle that case, instead of intentionally crashing the server.
MySQL 5.7 added code to push down the LIMIT to fulltext search

Bug #22709692 FTS QUERY EXCEEDS RESULT CACHE LIMIT
The code was disabled when MySQL 5.7.9 was merged to MariaDB 10.2.2.
We shall remove the disabled code and unnecessary variables.
When MySQL 5.6.10 introduced innodb_read_only mode, it skipped the
creation of the InnoDB buffer pool dump/restore subsystem in that mode.
Attempts to set the variable innodb_buf_pool_dump_now would have
no effect in innodb_read_only mode, but the corresponding condition
was forgotten in from the other two update functions.
MySQL 5.7.20 would fix the innodb_buffer_pool_load_now,
but not innodb_buffer_pool_load_abort. Let us fix both in MariaDB.
Port the previous patch:
- Implement MariaDB's Group Commit API. This is a first
attempt which lacks the expected performance.
To newer MariaDB (which includes newer MyRocks)

Bug#26361149 MYSQL SERVER CRASHES AT: COL IN(IFNULL(CONST,
COL), NAME_CONST('NAME', NULL))
Backport of Bug#19143243 fix.
NAME_CONST item can return NULL_ITEM type in case of incorrect arguments.
NULL_ITEM has special processing in Item_func_in function.
In Item_func_in::fix_length_and_dec an array of possible comparators is
created. Since NAME_CONST function has NULL_ITEM type, corresponding
array element is empty. Then NAME_CONST is wrapped to ITEM_CACHE.
ITEM_CACHE can not return proper type(NULL_ITEM) in Item_func_in::val_int(),
so the NULL_ITEM is attempted compared with an empty comparator.
The fix is to disable the caching of Item_name_const item.
Partition wasn't setting HA_OPTION_PACK_RECORD on ALTER TABLE
if the row format was PAGE.
(so one bit in the null bitmap was reserved for a deleted bit -
see make_empty_rec - and all actual null bits were one off)
if it's a DROP TABLE, we cannot detect whether a table is
temporary by looking in thd->temporary_tables - because the
table might simply not exist at all.

MDEV-8960: Can't refer the same column twice in one ALTER TABLE
Problem was that if column was created in alter table when
it was refered again it was not tried to find from list
of current columns.
mysql_prepare_alter_table:
There is two cases
(1) If alter table adds a new column and then later alter
changes the field definition, there was no check from
list of new columns, instead an incorrect error was given.
(2) If alter table adds a new column and then later alter
changes the default, there was no check from list of
new columns, instead an incorrect error was given.
