Replace variable length arrays in MinSumAlgorithm::finalp() with a

Variable length arrays are a compiler extension and are not part of
standard C++. The replacement preserves the existing contiguous memory

Remove an inadvertent '>' character from the
QCoreApplication::applicationVersion() call in the startup version
logging for both appbench and appsrv.
This typo was identified by cppcheck during static analysis. Correcting
the expression restores valid C++ syntax, allowing the applications to
compile correctly and report their version information in the startup
log.

Replace signed %ld format specifiers with unsigned %lu conversions when
printing values stored as unsigned long.
The previous format strings passed unsigned values to signed printf
conversions, which could result in undefined behavior due to variadic
argument type mismatches. These issues were identified by cppcheck
invalidPrintfArgType_sint warnings.
Use format specifiers matching the actual argument types to ensure
correct and portable printf usage.

Change the ft8_crc message length parameter from signed int to uint32_t
since it represents a non-negative FT8 message bit count.
GCC reported a potential buffer overflow in the memcpy() call:
warning: ‘__builtin_memcpy’ specified bound between
18446744073709551560 and 18446744073709551564 exceeds maximum object size
[-Wstringop-overflow=]
The warning was caused by the signed message length allowing negative
values to be converted into a very large unsigned size when calculating
the memcpy() byte count.
Using an unsigned fixed-width type better represents the valid range of
the FT8 message length and prevents invalid negative lengths from being
interpreted as extremely large memory operations.

Remove an invalid out-of-bounds array access that attempted to handle
ERROR_INSUFFICIENT_BUFFER. The statement did not resize the fixed-size
buffer and had no effect other than invoking undefined behavior.
The function only uses QueryDosDeviceA() as an existence check for COM
ports, so removing the dead error-handling code does not change its
behavior.

cppcheck reported that the std::copy() call used iterators from different
containers when restoring ADSB demod table column sizes.
The copy operation used settings.m_columnSizes as the source start iterator
but settings.m_columnIndexes as the source end iterator. This was likely a
copy/paste error and resulted in an invalid iterator range.
Use settings.m_columnSizes for both source iterators so column size settings
are restored correctly.

cppcheck reported that GLScopeSettings::operator=() did not assign the
m_freerun member variable.
m_freerun is part of the GLScope configuration state: it is initialized
in resetToDefaults(), and is persisted through serialize()/deserialize().
However, when a GLScopeSettings object was copied using the assignment
operator, the freerun state was not transferred from the source object.
This could result in two GLScopeSettings instances having different
freerun values after assignment, with the destination object retaining
its previous value instead of matching the source object.
Add the missing m_freerun assignment to ensure operator=() performs a
complete copy of the settings state and matches the existing
serialization behavior.

Fix cppcheck warnings where array elements were accessed before validating
their indices. Reorder conditional expressions to ensure bounds checks are
performed before array accesses, taking advantage of C++ short-circuit
evaluation.
In EMNR::NP::interpM(), check the index limit before accessing xvals[idx].
In SNBA::scanFrame(), verify i is within the merit array bounds before
evaluating merit[i].
These changes improve defensive programming practices and prevent potential
undefined behavior if an index exceeds the valid range. No functional changes.

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.
