Fix Bug#43309 Test main.innodb can't be run twice

Make the innodb mysql-test more flexible by inspecting how much a
variable of interest has changed since the start of the test. Do not
assume the variables have zero values at the start of the test.

Restore the state of INNODB_THREAD_CONCURRENCY to silence this warning:

  TEST                                      RESULT   TIME (ms)

  MTR's internal check of the test case 'main.innodb' failed.
  This means that the test case does not preserve the state that existed
  before the test case was executed.  Most likely the test case did not
  do a proper clean-up.
  This is the diff of the states of the servers before and after the
  test case was executed:

Remember the acquired record locks per table handle (row_prebuilt_t)
rather than per transaction (trx_t), so that unlock_row should successfully
unlock all non-matching rows in multi-table operations.
This deficiency was found while investigating Bug #39320.

    BUG#42445 Warning messages in innobase/handler/ha_innodb.cc
          
    There was a type casting problem in the storage/innobase/handler/ha_innodb.cc,
    (int ha_innobase::write_row(...)). Innobase uses has an internal error variable
    of type 'ulint' while mysql uses an 'int'. 
          
    To fix the problem the function manipulates an error variable of
    type 'ulint' and only casts it into 'int' when needs to return the value.
  modified:
    storage/innobase/handler/ha_innodb.cc

It was not a SIGSEGV but an assertion failure. The assertion was checking
the invariant that *first_value passed in by MySQL doesn't contain a value
that is greater than the max value for that type. The assertion has been
changed to a check and if the value is greater than the max we report a
generic AUTOINC failure.

changes to the autoinc handling.

1. To fix the immediate problem from the bug report, we must ensure that the
   value written to the table is always less than the max value stored in
   dict_table_t.

2. The second related change is that according to MySQL documentation when
   the offset is greater than the increment, we should ignore the offset.

the following huge merge, but we are merging only changes to that file]

    Bug#31177: Server variables can't be set to their current values
    
    Bounds-checks and blocksize corrections were applied to user-input,
    but constants in the server were trusted implicitly. If these values
    did not actually meet the requirements, the user could not set change
    a variable, then set it back to the (wonky) factory default or maximum
    by explicitly specifying it (SET <var>=<value> vs SET <var>=DEFAULT).
    
    Now checks also apply to the server's presets. Wonky values and maxima
    get corrected at startup. Consequently all non-offsetted values the user
    sees are valid, and users can set the variable to that exact value if
    they so desire.

rec_set_nth_field(): When the field already is SQL null,

Normally, MySQL does not pass "do-nothing" updates to the storage engine.
When it does and a column of an InnoDB table that is in ROW_FORMAT=COMPACT
is being updated from NULL to NULL, the InnoDB buffer pool will be corrupted
without this fix.

InnoDB previously treated savepoints as a stack e.g.,
  SAVEPOINT a;
  SAVEPOINT b;
  SAVEPOINT c;
  SAVEPOINT b; <- This would delete b and c.

This fix changes the behavior to:
  SAVEPOINT a;
  SAVEPOINT b;
  SAVEPOINT c;
  SAVEPOINT b; <- Does not delete savepoint c

row-based replication (Bug #39648).

row_prebuilt_t: Add default_rec, for the default values of the columns in
MySQL format.

row_sel_store_mysql_rec(): Use prebuilt->default_rec instead of
padding columns.

It is a bug in unused code. If we don't calculate the hash value when
calculating the mutex number then two pages which map to same hash
value can get two different mutex numbers.

Merge a change from MySQL to fix the failing innodb_bug34300 mysql-test:

  main.innodb_bug34300           [ fail ]
  
  mysqltest: At line 11: query 'SET @@max_allowed_packet=16777216' failed: 1621: SESSION variable 'max_allowed_packet' is read-only. Use SET GLOBAL to assign the value
  
  Aborting: main.innodb_bug34300 failed in default mode.

  message:
    A fix for Bug#22891 "session level max_allowed_packet can be
    set but is ignored".
  
    This patch makes @@session.max_allowed_packed and
    @@session.net_buffer_length read-only as suggested in the bug
    report. The user will have to use SET GLOBAL (and reconnect)
    to alter the session values of these variables.
  
    The error string ER_VARIABLE_IS_READONLY is introduced.
  
    Tests are modified accordingly.

Fix Bug#40760 "set global innodb_thread_concurrency = 0;" is not safe

The config param innodb_thread_concurrency is dynamically set and is
read when a thread enters/exits innodb. If the value is changed between
the enter and exit time the behaviour becomes erratic.
The fix is not to use srv_thread_concurrency when exiting, instead use
the flag trx->declared_to_be_inside_innodb.

comment. In the UTF-8 encoding, ASCII takes 1 byte per character, while
the "latin1" character set (normally ISO-8859-1, but in MySQL it actually

size of a SQL NULL column. (Bug #40369)

When MySQL Bug #20877 was fixed in r834, this function was
accidentally modified to return 0 or 1. Apparently, the only impact of
this bug is that fixed-length columns cannot be updated in-place from
or to SQL NULL, even in ROW_FORMAT=REDUNDANT.  After this fix,
fixed-length columns in ROW_FORMAT=REDUNDANT will have a constant
storage size as they should, no matter if NULL or non-NULL.  The bug
caused fixed-length NULL columns to occupy 1 byte.

Simplify the autoinc initialization code. This removes the
non-determinism related to reading the table's autoinc value for the first
time. This change has also reduced the sizeof dict_table_t by sizeof(ibool)
bytes because we don't need the dict_table_t::autoinc_inited field anymore.

Check column value against the col max value before updating the table's
global autoinc counter value. This is part of simplifying the AUTOINC
sub-system. We extract the type info from MySQL data structures at runtime.

This fixes Bug#37788 InnoDB Plugin: AUTO_INCREMENT wrong for compressed tables
