Do not resend metadata, if metadata does not change between prepare and
execute of prepared statement, or between executes.
Currently, metadata of *every* prepared statement will be checksummed,
and change is detected once checksum changes.
This is not from ideal, performance-wise. The code for
better/faster detection of unchanged metadata, is already in place, but
currently disabled due to PS bugs, such as MDEV-23913.

The COM_MULTI did not take off. No connector is using it.
Remove related code from server, and client.
If anything it is a step simplification of already-bloated
dispatch_command(), and related code.

Description:- Mysql client crashes when trying to connect
to a fake server which is sending incorrect packets.
Analysis:- Mysql client crashes when it tries to read
server version details.
Fix:- A check is added in "red_one_row()".

ANALYSIS:
=========
'CREATE TABLE' query with a large value for 'CONNECTION'
string reports an incorrect error.
The length of connection string is stored in .frm in two
bytes (max value= 65535). When the string length exceeds
the max value, the length is truncated to fit the two
bytes limit. Further processing leads to reading only a
part of the string as the length stored is incorrect. The
remaining part of the string is treated as engine type and
hence results in an error.
FIX:
====
We are now restricting the connection string length to 1024.
An appropriate error is reported if the length crosses this
limit.
NOTE:
=====
The 'PASSWORD' table option is documented as unused and
processed within a dead code. Hence it will not cause
similar issue with large strings.

- Add new "format section" in extra data segment with additional table and
column properties. This was originally introduced in 5.1.20 based MySQL Cluster
- Remove hardcoded STORAGE DISK for table and instead
output the real storage format used. Keep both TABLESPACE
and STORAGE inside same version guard.
- Implement default version of handler::get_tablespace_name() since tablespace
is now available in share and it's unnecessary for each handler to implement.
(the function could actually be removed totally now).
- Add test for combinations of TABLESPACE and STORAGE with CREATE TABLE
and ALTER TABLE
- Add test to show that 5.5 now can read a .frm file created by MySQL Cluster
7.0.22. Although it does not yet show the column level attributes, they are read.

indefinitely.
The server could be tricked to read packets indefinitely if it
received a packet larger than the maximum size of one packet.
This problem is aggravated by the fact that it can be triggered
before authentication.
The solution is to no skip big packets for non-authenticated
sessions. If a big packet is sent before a session is authen-
ticated, a error is returned and the connection is closed.

Support for flushing individual logs, so that the user can
selectively flush a subset of the server logs.
Flush of individual logs is done according to the
following syntax:
FLUSH <log_category> LOGS;
The syntax is extended so that the user is able to flush a
subset of logs:
FLUSH [log_category LOGS,];
where log_category is one of:

WL#4098: Add a status flag for slow queries
Add new result set status flag SERVER_QUERY_WAS_SLOW in mysql_com.h.
There is no server-side implementation to actually set this flag at this
time. This patch simply defines the interface so that applications can
make use of it. See the worklog for background.

some other minor revisions.
This patch implements:
WL#4264 "Backup: Stabilize Service Interface" -- all the
server prerequisites except si_objects.{h,cc} themselves (they can
be just copied over, when needed).
WL#4435: Support OUT-parameters in prepared statements.
(and all issues in the initial patches for these two
tasks, that were discovered in pushbuild and during testing).
Bug#39519: mysql_stmt_close() should flush all data
associated with the statement.
After execution of a prepared statement, send OUT parameters of the invoked
stored procedure, if any, to the client.
When using the binary protocol, send the parameters in an additional result
set over the wire. When using the text protocol, assign out parameters to
the user variables from the CALL(@var1, @var2, ...) specification.
The following refactoring has been made:
- Protocol::send_fields() was renamed to Protocol::send_result_set_metadata();
- A new Protocol::send_result_set_row() was introduced to incapsulate
common functionality for sending row data.
- Signature of Protocol::prepare_for_send() was changed: this operation
does not need a list of items, the number of items is fully sufficient.
The following backward incompatible changes have been made:
- CLIENT_MULTI_RESULTS is now enabled by default in the client;
- CLIENT_PS_MULTI_RESUTLS is now enabled by default in the client.
