The limit of socket length on unix according to libc is 108, see
sockaddr_un::sun_path, but in the table it is a string of max length
64, which results in truncation of socket and failure to connect by
plugins using servers such as spider.
MySQL-Connector-Net casts SEQ_IN_INDEX to uint and will
raise an exception if the type is a System.Int64.
As we don't support a huge number of multi-columns in
an index reducing to a uint is sufficient to represent
all values and maintain compatibility with MySQL-Connector-Net.
This matches the type (uint) returned by MySQL-8.3 and 8.0.

Field_string::val_int(), Field_string::val_real(), Field_string::val_decimal()
passed the whole buffer of field_length bytes to data type conversion routines.
This made conversion routines to print redundant trailing spaces in case of warnings.
Adding a method Field_string::to_lex_cstring() and using it inside
val_int(), val_real(), val_decimal(), val_str().
After this change conversion routines get the same value with what val_str() returns,
and no redundant trailing spaces are displayed.
The IDENT_sys doesn't include keywords, so the function with the
keyword name can be created, but cannot be called.
Moving keywords to new rules keyword_func_sp_var_and_label and
keyword_func_sp_var_not_label so the functions with these
names are allowed.
standard table KEY_COLUMN_USAGE should only show keys where
a user has some privileges on every column of the key
standard table TABLE_CONSTRAINTS should show tables where
a user has any non-SELECT privilege on the table or on any column
of the table
standard table REFERENTIAL_CONSTRAINTS is defined in terms of
TABLE_CONSTRAINTS, so the same rule applies. If the user
has no rights to see the REFERENCED_TABLE_NAME value, it should be NULL
SHOW INDEX (and STATISTICS table) is non-standard, but it seems
reasonable to use the same logic as for KEY_COLUMN_USAGE.

Task 6:
We can find the .frm type of file. If it is sequence then is_sequence
passed to dd_frm_type() will be true. Since there is already a check
to give error message if we trigger is on temporary table or view, an
additional condition is added to check if .frm is sequence
(is_sequence==true) and error message is changed to show
"Trigger's '%-.192s' is view, temporary table or sequence" instead of
"Trigger's '%-.192s' is view or temporary table".
The 10.5 version of the patch.
Removing DEFAULT from INFORMATION_SCHEMA columns.
DEFAULT in read-only tables is rather meaningless.
Upgrade should go smoothly.
Also fixes:
MDEV-20254 Problems with EMPTY_STRING_IS_NULL and I_S tables
