Description

MySQL supports an extension for optionally specifying the display width of integer data types in parentheses following the base keyword for the type. For example, INT specifies an INT with a display width of four digits. This optional display width may be used by applications to display integer values having a width less than the width specified for the column by left-padding them with spaces. (That is, this width is present in the metadata returned with result sets. Whether it is used or not is up to the application.)

The display width does not constrain the range of values that can be stored in the column. Nor does it prevent values wider than the column display width from being displayed correctly. For example, a column specified as SMALLINT has the usual SMALLINT range of -32768 to 32767, and values outside the range permitted by three digits are displayed in full using more than three digits.

Thus the correct translation for INT would be INT / INTEGER / INT4.

More discrepancies show up with other field types, resulting in the install tool database compare showing changes that are never going to get resolved.

TINYTEXT will be created as VARCHAR and reported as VARCHAR
TEXT and MEDIUMTEXT will be created/reported as LONGTEXT

[TASK] dbal: Move MySQL / DBMS field type translation into DBMS Specifics

The function used by the DBAL provide a very coarse and generic translations
between the ADdb meta types and the MySQL native types. This results in
ambiguities that can't properly be resolved and leads to changes in the
install tool schema migration that can never be resolved.

The default DBMS specifics provided resemble the current output of the
functions and don't result in any changes to the DBMS schema.

[FEATURE] dbal: DBMS specific conversion between Meta/MySQL field types

This patch changes the implementation of the methods that convert
between ADOdb meta field types and MySQL native field types to allow
overriding the conversion per data type.

The PostgresSpecifics provide better matching of BLOB, SERIAL, DOUBLE
and INTEGER types.
