WSJT-X/Configuration.hpp
Bill Somerville 8d3c86c399 Disallow multiple instances without a unique rig name
Because of confilicts using the  shared memory to communicate with jt9
only one instance of WSJT-X may run with each unique key (rig name).

Added a QLockFile for each unique  key in the temp directory and logic
to deal with stale locks and retries.

//
// Responsibilities
//
// Provides management of the CAT and PTT rig interfaces, providing
// control access via a minimal generic set of Qt slots and status
// updates via Qt signals. Internally the rig control capability is
// farmed out to a separate thread since many of the rig control
// functions are blocking.
//
// All user settings required by the wsjtx GUI are exposed through
// query methods.
//
// The QSettings instance passed to the constructor is used to read
// and write user settings.
//
// Pointers to three QAbstractItemModel objects are provided to give
// access to amateur band information, user working frequencies and,
// user operating band information. These porovide consistent data
// models that can be used in GUI lists or tables or simply queried
// for user defined bands, default operating frequencies and, station
// descriptions.
