Support early IBB use in Jingle File Transfer
Previously Jingle File Transfer in Swiften only used IBB
transport as fallback mechanism. With this patch Swiften will
use IBB transport candidates directly in the first
session-initate/session-accept message if the other party
only supports IBB.
Fixed a ASAN reported heap-use-after-free in
SOCKS5BytestreamServerManager.cpp while testing.
Test-Information:
./scons test=system passed without error.
Testing all sender/receiver file-transfer option configurations
with FileTransferTest resulting in expected behavior.
Successfully transferring a file between two Swift instances.
