API: add `GDBDebugger >> getParameter:` and `setParameter:to:`
...to get / set GDB internal parameters such as prompt. The only
complication here is that when a parameter is set by MI `-gdb-set`
command, the `=cmd-param-changed' notification is not sent. This
may or may not be a GDB bug.
To make this transparent to `libgdbs` clients, intercept all `-gdb-set`
commands and when sucessful, emit the event manually. This way, client
may rely on value change notification (`GDBCmdParamChangedEvent`) to
detect changes.

A GDBRemoteProcess represent a GDB process external to libgdbs. This means
the user us responsible for launching the actuall GDB and setting up
a connection to its MI channel:
| process debugger |
process := GDBRemoteProcess new.
process debuggerInput: miChannel writeStream.
process debuggerOutput: miChannel readStream.
debugger := GDBDebugger newWithProcess: process.
Onw way to use this might be to run GDB through
`socat` [1], exposing it's MI channel over TCP socket:
socat TCP4-LISTEN:1234 EXEC:'gdb -i mi2'
This is useful for example when host running libgdbs
does not have suitable GDB installed or on environments
where no 'native' implementation of `GDBProcess` (such as
`GDBStXUnixProcess`) exists (such as Bee Smalltalk)
