- Fix MDEV-5393 and MDEV-5434. It is a major update of ODBC catalog tables

  processing that takes care of:
  - Drastically reduce the amount of storge needed to process them.
  - Handle longjmp's.
  - Makes the line limit an opion (MAXRES)
  - Schema can also be specified with the DBNAME option.
  - Issue warnings on fetch errors or when result lines have been limited.
  - Change some column names to reflect ODBC version 3 standard.
  The documentation have been updated accordingly
