MDEV-23497 Make ROW_FORMAT=COMPRESSED read-only by default

Let us introduce the parameter innodb_read_only_compressed
that is ON by default, making any ROW_FORMAT=COMPRESSED tables
read-only.

I developed the ROW_FORMAT=COMPRESSED format based on
Heikki Tuuri's rough design between 2005 and 2008. It might
have been a good idea back then, but no proper benchmarks were
ever run to validate the design or the implementation.

The format has been more or less obsolete for years.
It limits innodb_page_size to 16384 bytes (the default),
and instant ALTER TABLE is not supported.

This is the first step towards deprecating and removing
write support for ROW_FORMAT=COMPRESSED tables.

MDEV-6348: mariadb crash signal 11

Analysis: sync array output function, should make sure that all
used pointers are valid before using them.

Merge revision 4225 from lp:maria/5.5.
