Adding freebsd support for Device Removal event

5.1.0: Device Removed Event Added

I am kinda excited, this is the first new feature added to RXTX in 11
years! it also happens to fix a 15 year old bug, present in the library
since USB to serial adapters were invented. The original developers
never imagined the event of removing hardware, because back then Serial
ports were built into the processor and could never be removed or added.

This feature will now add a user level event when the hardware is
removed. The user can then perform a shutdown procedure, since a
connection will be needed after the hardware is removed.

This also causes the Monitor thread that used to become a zombie to die
properly.
