Bugfix release of JayBird 1.5.4

What's new in JayBird 1.5.x versions:

- full JDBC 2.0 compatibity (passed JDBC CTS 1.3.1 suite)
  - full callable statement support
  - batch updates
  - support of ResultSet.TYPE_SCROLL_INSENSITIVE
  - X/Open SQL states are reported by SQLException
  - escaped syntax support for stored procedures and functions
  - fixed JDBC specs deviations from 1.0.1 release

- type 2 JDBC driver support: now you can use gds32.dll/libgds.so, fbclient.dll/libfbclient.so and
fbembed.dll/libfbembed.so (requires native library, available as separate package), it allows you to:

  - use local connectivity when application runs on localhost
  - use embedded version of the engine

You can also try using the driver with InterBase 6.x, 7.x.

- multi-thread safety: now you can use one connection from multiple threads

- introduced Firebird-specific interfaces: FirebirdConnection, FirebirdStatement, FirebirdPreparedStatement and FirebirdBlob:
you can utilize Firebird-specific features.

- completely rewritten JDBC connection pool with prepared statement caching, more properties to control DataSource and
ConnectionPoolDataSource objects.

- savepoint support for Firebird 1.5 (JDBC 3.0 only, hence for JDK 1.4.x only)
