374783c3d9 MDEV-28152 Features for sequences
- Add `as <int_type>` to sequence creation options
  - int_type can be signed or unsigned integer types, including
    tinyint, smallint, mediumint, int and bigint
  - Limitation: when alter sequence as <new_int_type>, cannot have any
    other alter options in the same statement
  - Limitation: increment remains signed longlong, and the hidden
    constraint (cache_size x abs(increment) < longlong_max) stays for
    unsigned types. This means for bigint unsigned, neither
    abs(increment) nor (cache_size x abs(increment)) can be between
    longlong_max and ulonglong_max
- Truncating maxvalue and minvalue from user input to the nearest max
  or min value of the type, plus or minus 1. When the truncation
  happens, a warning is emitted
- Information schema table for sequences

9854fb6fa7 MDEV-31003: Second execution for ps-protocol
This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.

7aa80ba66b Sequences with negative numbers and auto_increment_increment crashes
This also fixes MDEV-16313 Assertion `next_free_value % real_increment == offset' fails upon CREATE SEQUENCE in galera cluster

Fixed by adding llabs() to assert.
Also adjusted auto_increment_offset to mod auto_increment_increment.
