* Fixed a bug in rdadmin(1) where clicking the 'OK' button
in the 'Edit Switcher' dialog would cause an error dialog to appear
with a 'primary serial device not active' warning. The following
devices are affected: 'Local GPIO', 'Local Audio Adapter',
'Logitek vGuest', 'Livewire LWRP Audio', and 'Kernel GPIO'.

'SAS USI (3 digit)'.
* Added an 'SAS USI (2 digit)' swticher driver in
'ripcd/sasusi2digit.cpp' and 'ripcd/sasusi2digit.h'.
* Fixed a bug in 'lib/rdmatrix.cpp' that caused the configuration
for 'Software Authority Protocol' to grey out the 'IP Address'
field when creating a new matrix.
* Added 'RDMatrix::SoftwareAuthority' to the 'RDMatrix::Type'
enumeration in 'lib/rdmatrix.cpp' and 'lib/rdmatrix.h'.
* Implemented a switcher driver for systems using Software Authority
Protocol in 'ripcd/swauthority.cpp' and 'ripcd/swauthority.h'.
* Added 'RDMatrix::ModemLines' to the 'RDMatrix::Type' enumeration
in 'lib/rdmatrix.cpp' and 'lib/rdmatrix.h'.
