Implementation of inferior PTY / IO needed

Cannot distinguish program output from gdb mi output

cdt-gdb-adapter would try to interpret every line as gdb mi output, which causes a problem because it cannot distinguish program output from that. For example:

In the image above, cdt-gdb-adapter tried to parse the line that's started with = or *, and failed.

Only parse the output after a line is finished

According to:
https://github.com/eclipse-cdt/cdt-gdb-adapter/blob/3b9442075d06759035dbae616dbbd9923b921bc6/src/MIParser.ts#L26
the MIParser only handle the output when a line is finished. In the case of program output, this can be really buggy.

Hmm the MI should really not be on the same channel as the program output.

I believe no one has implemented this functionality yet - probably because most of the usecases for the adapter so far are embedded. On Linux probably want to use -inferior-tty-set and on Windows -gdb-set new-console on.

There is already PTY support needed by the new-ui when openGdbConsole is set.

Patches welcome.

I did a first pass of Linux support for this in #252. If anyone wants to review that to see what they think that would be much appreciated.
