/**
* \brief Query the remote stub for its name and version via qGDBServerVersion
*
* qGDBServerVersion is an LLDB protocol extension. The reply is a list of
* `key:value;` pairs, e.g. `name:debugserver;version:902.0.0;`. Stubs that do
* not implement it (such as gdbserver) reply with an empty packet, in which
* case this does nothing beyond emitting a debug log line.
