I would think we would try to enable this using something like:
QEnableErrorStrings
And if the the server responds with "OK" then we know it is enabled. By default
the server should not enable any fancy features without being asked. We would
like lldb-server to stay compatible with other GDB remote clients.
The error string should be hex ASCII encoded so the string can contain any
characters. Any string that can contain any content should be hex ASCII encoded.

Maybe:
```
EXX;AAAAAA
Where XX is a hex byte error number, followed by a semicolon and where AAAAAA
is a hex ascii encoded error message.
