Jaybird milestone : removal of JNI C++ wrappers

Removal of old GDS API:

The old GDS API (org.firebirdsql.gds.GDS) has been removed. This removal
includes a number of related classes and methods.

Type 2 (native) and embedded driver

Jaybird no longer needs a jaybirdxx.dll or jaybirdxx.so for the Type 2 and embedded driver. Jaybird now uses JNA to access the client library.

If you want to use the Type 2 driver, or Firebird embedded, then you need to include the jna-x.x.x.jar on the classpath. The fbclient.dll, fbembed.dll, libfbclient.so, or libfbembed.so need to be on the path.
