Warnings while build with GCC 9

[Vascom]

Fedora doing MassRebuild with GCC 9 and encfs has some new warnings.

BUILDSTDERR: /builddir/build/BUILD/encfs-1.9.5/encfs/NullNameIO.cpp: In member function 'virtual encfs::Interface encfs::NullNameIO::interface() const': BUILDSTDERR: /builddir/build/BUILD/encfs-1.9.5/encfs/NullNameIO.cpp:48:50: warning: implicitly-declared 'encfs::Interface::Interface(const encfs::Interface&)' is deprecated [-Wdeprecated-copy] BUILDSTDERR: 48 | Interface NullNameIO::interface() const { return NNIOIface; } BUILDSTDERR: | ^~~~~~~~~ BUILDSTDERR: In file included from /builddir/build/BUILD/encfs-1.9.5/encfs/NullNameIO.h:26, BUILDSTDERR: from /builddir/build/BUILD/encfs-1.9.5/encfs/NullNameIO.cpp:21: BUILDSTDERR: /builddir/build/BUILD/encfs-1.9.5/encfs/Interface.h:60:14: note: because 'encfs::Interface' has user-provided 'encfs::Interface& encfs::Interface::operator=(const encfs::Interface&)' BUILDSTDERR: 60 | Interface &operator=(const Interface &src); BUILDSTDERR: | ^~~~~~~~ BUILDSTDERR: /builddir/build/BUILD/encfs-1.9.5/encfs/NullNameIO.cpp: In static member function 'static encfs::Interface encfs::NullNameIO::CurrentInterface()':

And one old warning

BUILDSTDERR: In file included from /builddir/build/BUILD/encfs-1.9.5/encfs/Context.cpp:27: BUILDSTDERR: /builddir/build/BUILD/encfs-1.9.5/encfs/Mutex.h: In member function 'bool encfs::EncFS_Context::usageAndUnmount(int)': BUILDSTDERR: /builddir/build/BUILD/encfs-1.9.5/encfs/Mutex.h:49:35: warning: 'lock.encfs::Lock::_mutex' may be used uninitialized in this function [-Wmaybe-uninitialized] BUILDSTDERR: 49 | if (_mutex) pthread_mutex_unlock(_mutex); BUILDSTDERR: | ~~~~~~~~~~~~~~~~~~~~^~~~~~~~ BUILDSTDERR: /builddir/build/BUILD/encfs-1.9.5/encfs/Context.cpp:97:8: note: 'lock.encfs::Lock::_mutex' was declared here BUILDSTDERR: 97 | Lock lock(contextMutex); BUILDSTDERR: | ^~~~ make[2]: Entering directory '/builddir/build/BUILD/encfs-1.9.5/x86_64-redhat-linux-gnu'

See all of them here https://kojipkgs.fedoraproject.org//packages/fuse-encfs/1.9.5/4.fc30/data/logs/x86_64/build.log

Please correct it so encfs will not have any build warning :)
