mariadb/storage/connect/filamdbf.h
Olivier Bertrand 82e746ea1b Put almost all function prototypes in header files that are
included by the program using them.

Continuing implementing the "catalog" tables (ex "info").
Already existing were the ODBC data source table and the
WMI column info table.

A common way to handle them will permit to develop many
other such tables. Implemented:

The ODBC column catalog table.
The ODBC tables catalog table.
The ODBC drivers catalog table.

The INFO table option is replaced by the CATFUNC string option
whode first letter specifies the information to retrieve:
C: Columns (of a table)
T: Tables  (of a database)
S: Data sources
D: Drivers
