DATV: Convert leansdr fail and fatal errors into C++ exceptions
...
The original leansdr code uses fatal() and fail() for unrecoverable errors by
terminating execution. When integrated into SDRangel, these error paths did
not provide a mechanism for the plugin to handle failures locally, allowing
initialization failures to escape the normal plugin lifecycle.
Convert leansdr fatal() and fail() handling into C++ exceptions so DATV can
detect framework initialization failures, report them, and cleanly return
control to SDRangel instead of allowing the error to terminate the application.
This behavior is desirable because a DATV framework configuration failure
should not bring down the entire application.
Catch initialization exceptions in DATVDemodSink::feed(), report the failure,
clean up the partially initialized framework, and return to the caller.
Add noreturn annotations to the leansdr error functions and include the
leansdr source in exception messages to make failures easier to diagnose.
This does not redesign leansdr error handling or provide recovery from
runtime DSP failures. It only adds an exception boundary between the
leansdr library code and the SDRangel plugin lifecycle.
noticed via cppcheck indicating many Array indexes could go out of bounds
due to fail and fatal returning.
