MDEV-39153 Fix sporadic main.change_master_default mismatch

The test used "restart_abort:" in the expect file, which MTR never
recognized. It fell through to the else branch, deleted restart_opts,
and started the server with defaults (heartbeat_period=60 instead of 0).

Replace restart_abort with direct --exec $MYSQLD calls.

MDEV-42003 Enhance mariadbd-multi to support mariadbd prefixes

- Update my.cnf options to support [mariadbd_multi] (same as
  [mysqld_multi]), and [mariadbd#] (same as [mysqld#]).
- Change all instances of mysqld to mariadbd, mysqladmin to mariadb-admin.
  - mysqld and mysqladmin can still be used as options and in config files
- mariadb-admin gets confused when both --socket and --port is provided.
  Now socket is used if --tcp-ip or --port is not used. Only one of
  --socket or --port is sent to mariadb-admin.
- A warning is given if a group number is used more than once, like
  [mysqld2] and [mariadbd2]. For compatibility with old configuration
  files, the options of all groups with the same number are combined,
  with later options overriding earlier ones.
- --print-commands will print all system commands to stdout
  (good for debugging)

MDEV-39441: Add dbug_print() helpers for join-related types

Introduces new dbug_print() functions for the following types:
  dbug_print(NESTED_JOIN)
  dbug_print(JOIN)
  dbug_print(TABLE_LIST)
  dbug_print(JOIN_TAB)
  dbug_print(List<Item>)

Typically pointers to instances of the given types are passed.
The dbug_print(List<Item>) is intended to show result row before
sending to client (e.g., invoke in debugger while tracing end_send)
but may work in other contexts.

These functions produce nicely formatted output, please use them
in conjunction with the formatted printfs available in GDB or LLDB:
  (gdb) printf "%s", dbug_print(join_tab)
  (lldb) p printf("%s", dbug_print(table))

Example output from dbug_print(JOIN) in LLDB.  The last line with
value 1302 is the number of characters produced by the printf
command.

(lldb) p printf("%s",dbug_print(join))

MDEV-40486 Length check for vector fields in CREATE TABLE ... SELECT

The changes of MDEV-39558 2b6529426a7e7c65d286e093d84138be9dcc34a3
added length check assertion in Field_varstring constructors, and
length check in type inference for SELECT set operations, to emit
errors before reaching the assertions.

That change caused an error to turn into an assertion failure in a
separate path, when the length limit violation is not detected before
tripping the assertion. So in this patch we fix it by adding an
earlier length check in that path.

The reason that we place this check inside
Item_func_vec_fromtext::fix_length_and_dec rather than say
`create_field_for_create_select is for consistency:

If

create table t1 as select
vec_fromtext(concat('[',group_concat(1),']')) as c1 from seq_1_to_64;

fails due to length limit violation, then so should

create table t1 (v vector(64) not null);
insert into t1 select vec_fromtext(concat('[',group_concat(1),']'))
from seq_1_to_64;

Also use max_char_length() instead of max_length. This is a more
accurate length of characters. And add handling of empty string edge
case. Added testcases accordingly.

The change that uses max_char_length() causes side effects where
creating a table using a VEC_FROMTEXT(CHAR(1)) would result in a
0-dimensional vector field. This is accurate but 0-dim vector table
fields should not be allowed. So we make cases like this result in
a one-dimensional field.

Also fixed the underflow in (args[0]->max_length - 1) * 2 when the
arg's max length is 0. Previously this underflow would cause

create table t1 select vec_fromtext(NULL)

to fail with ER_TOO_BIG_FIELDLENGTH. Now it will be a VECTOR(1) field

MDEV-40801 ppc64le ro_after_init isn't pagesize aligned

Align ro_after_init using MAXPAGESIZE instead of COMMONPAGESIZE.

COMMONPAGESIZE may be smaller than the actual page size supported by
the target ABI. This can leave ro_after_init sharing an OS page with
adjacent sections, causing mprotect() to change permissions on data
outside ro_after_init.

Use MAXPAGESIZE so the section boundaries are aligned to the maximum
page size required by the target linker/ABI.

This is particularly important on architectures such as ppc64le and
aarch64, where the runtime page size can differ from COMMONPAGESIZE.

Before:
  .data          0x...1b80000
  ro_after_init  0x...1c70000
  .bss          0x...1c72000

After:
  ro_after_init starts and ends on MAXPAGESIZE boundaries, ensuring
  mprotect() only affects pages belonging to ro_after_init.

MDEV-40639 Open SYS_REFCURSOR crash, if many cursors inside a function

Problem:

If:
- A routine A() opened a SYS_REFCURSOR with a function B() in the SELECT list
- The function B() also opened some SYS_REFCURSORs

Then reallocation of the cursor array THD::m_statement_cursors could happen
during the execution of B(), so all sp_cursor_array_element pointers inside
sp_instr_copen_by_ref::exec_core() of routine A() became invalid.

Fix:

Chaging the data type of sp_cursor_array:
- from Dynamic_array<sp_cursor_array_element>
- to Dynamic_array<sp_cursor_array_element*>

So now only reallocations of the array of cursor pointers happen,
while sp_cursor_array_element instances always stay on their originally
allocated memory positions.

Note:
sp_cursor_array_element instances are allocated using the standart C++ "new"
and deleted using the standard C++ "delete". Using a MEM_ROOT does not
seem to be relevant here.

dcbstps is a Power 10 instruction. The default target arch on most

Added the target power10 to the function pmem_phwsync. The execution
of this function is gated on the ISA 3.1 in pmem_persist_init so
there's no chance of a SIGILL.

clang supports this target as arch=pwr10 and gcc as cpu=power10.

Applying HEX encoding write writting an ENUM/SET TYPELIB to FRM
if the TYPELIB has 0x00 bytes in the value.

This HEX encoding was earlier used only to write UCS2/UTF16/UTF32 TYPELIBs.

A new flag FIELDFLAG_FRM_HEX_ENCODED_TYPELIB was added to indicate
that the TYPELIB is hex encoded. It's used only inside FRM.
Note, it's mangled with FIELDFLAG_TREAT_BIT_AS_CHAR.
This should not be harmful:
- BIT and ENUM/SET columns are handled by two separate code branches
  when opening an FRM
- The flag is unset immediately after decoding TYPELIB, so the rest
  of the code does not se an unexpected flag combination.

The lotofstack test, the only user of not_ubsan.inc, has this
exclusion because the stack size under UBSAN lacks predictability.

MDEV-41655 caching_sha2_password does not limit the password length

let's tighten the limits to be closer to actual OpenSSL limits.

Encrypting with RSA, 2048-bit key and PKCS1 OAEP padding *always*
produces the ciphertext of 256 bytes. And to fit in this, the plaintext
cannot be longer than 214 bytes. Assuming the user can generate her
own keys, 512 bytes would be enough for 4096-bit key. Larger, 8192-bit
keys don't work anyway (don't fit in public_key[] buffer).

And also let's reject too long passwords that can never authenticate.

MDEV-39795: Assertion `n_reserved > 0' failed

Problem:
========

1. Assertion `n_reserved > 0` failed in fseg_create():

fsp_reserve_free_extents() has a special condition for small
tablespaces where it reserves individual pages instead of full
extents. In such cases, n_reserved can be 0 even when the
reservation succeeds, causing the assertion ut_ad(n_reserved > 0)
to fail incorrectly.

The code was checking n_reserved to determine whether a reservation
had already been attempted, but this logic breaks for small
tablespaces where pages, rather than extents, are reserved.

2. Encryption metadata not cleared for compressed-only pages:

buf_page_encrypt() only cleared encryption-related metadata
fields (key-version and crypt-checksum) when the page was
neither encrypted nor compressed. However, these fields should
also be cleared when page_compressed is true but encrypted is
false, to avoid leaving stale encryption metadata in
compressed-only pages.

Solution:
=========

buf_page_encrypt(): Refactored the early-return logic. Encryption
metadata fields are now cleared whenever encrypted is false,
regardless of page_compressed. The function returns early only
when both !encrypted and !page_compressed.

fseg_create(): Reintroduced a boolean variable `reserved` to track
whether fsp_reserve_free_extents() has been attempted (removed as
part of MDEV-38419 | c7313da), replacing assertion `n_reserved > 0`.
Added an early return when DB_DECRYPTION_FAILED is encountered
during inode allocation.

my_error_innodb(): Added handling for DB_DECRYPTION_FAILED to
report decryption errors to the user through ER_GET_ERRMSG.
