We don't want them to be inherited on exec(). We use exec() to run Transceiver and it OpenBTS process crashes, transceiver becomes owner of all LISTEN sockets.
This patch adds ability to connect to OpenBTS CLI with TCP socket and UNIX socket. This is configurable in the config file. To connect to the CLI use apps/OpenBTScli executable, which reads configuration from the same config file.
gethostbyname() is not thread-safe. It's recommended to use gethostbyname_r() or gethostbyname2_r() instead.
