Ntrip broadcaster written in c and libev.

For now, it can now transmit data between ntrip servers and ntrip clients, without source table and authorization support.

Need cmake and git and libev.

git clone https://github.com/lazytinker/ntripcaster.git
cd ntripcaster
git submodule update --init

mkdir build
cd build
cmake ..
make

Run it, it will listen on port 1024.
