Go VLBI Field System library

This library implements pure Go access to the VLBI Field System shared memory and semaphores.

Some high level interfaces are provided for supported all FS versions, but access for a particular version can be done via reflect.

Write access is not tested and while should work, will require care and understanding of the FS idioms.

FS scheduling and class buffers not implemented yet.

This includes a modified version of cgo for generating the interface. This code is covered by its original license.
