Bug#445657: libzrtpcpp ABI breakage - sendDataRTP removed in 0.9.2

[Werner Dittmann]

Mark,

sorry for causing trouble here - I'm in the process to do a
"offical" release libzrtpcpp in 2-3 weeks after some more regressions
with the original Zfone implementation. The ZRTP specifications
changes quite a lot, thus the ABI is incompatible. The best way
to overcome this is to recompile twinkle with the new libzrtcpp
files (headers and alike).

Regards,
Werner
